How To Store Bitcoin On USB Stick - What is Bitcoin ...

What I currently use for privacy (after almost 2 years of long investing into it)

First of all, my threat model: I'm just an average person that wants to AVOID the maximum I can to be monitored and tracked by the government and big corps, a lot of people out there REALLY hate me and I've gone through lots of harassment and other stuff, I also plan to take my activism and love for freedom more seriously and to do stuff that could potentially lead me to very high danger or even put my life on the line. That being said, my main focus is on something that is privacy-friendly but also something with decent security (no point having a lot of privacy if a script kiddie can just break into it an boom, everything is gone) anonymity is also desirable but I'm pretty aware that true 100% anonymity is simply not possible and to achieve the maximum you can of it currently you'd have to give up A LOT of stuff in which I don't think I really could. So basically, everything that I said + I don't want to give up some hobbies of mine (as playing games etc)
Here's what I use/have done so far, most of it is based on list and research I've done.
Google Pixel 3a XL running GrapheneOS
Apps: Stock apps (Vanadium, Gallery, Clock, Contacts etc) + F-DROID, NewPipe, OsmAnd+, Joplin, Tutanota, K-9 Mail, Aegis Authenticator, KeePassDX, Syncthing, Signal, Librera PRO, Vinyl, Open Camera and Wireguard.
I also use BlahDNS as my private DNS.
Other smartphone stuff/habits: I use a Supershieldz Anti Spy Tempered Glass Screen Protector on my phone and I also have a Faraday Sleeve from Silent Pocket which my phone is on most of the times (I don't have smartphone addiction and would likely advice you to break free from smartphone addiction if you have it). I NEVER use bluetooth (thank god Pixel 3a have a headphone jack so yeah, no bluetooth earphones here) and always keep my Wi-Fi off if I'm not using it.
I have a desktop that I built (specs: Asus B450M Gaming, AMD Ryzen 3 3300X, Radeon RX 580 8GB, 16GB DDR4 2666Mhz, 3TB HDD, 480GB SSD) that is dualbooted with QubesOS and Arch Linux.
Qubes is my main OS that I use as daily driver and for my tasks, I use Arch for gaming.
I've installed linux-hardened and its headers packages on my Arch + further kernel hardening using systctl and boot parameters, AppArmor as my MAC system and bubblewrap for sandboxing programs. I also spoof my MAC address and have restricted root access, I've also protected my GRUB with password (and use encrypted boot) and have enabled Microcode updates and have NTP and IPV6 disabled.
Also on Arch, I use iptables as a firewall denying all incoming traffic, and since it's my gaming PC, I don't game on the OS, instead, I use a KVM/QEMU Windows VM for gaming (search "How I Built The "Poor-Shamed" Computer" video to see what I'm talking about) I also use full disk encryption.
E-Mails: I use ProtonMail (Plus Account paid with bitcoin) and Tutanota (free account as they don't accept crypto payment yet, come on Tutanota, I've been waiting for it for 2 years already) since I have plus account on ProtonMail it allows me to use ProtonMail Bridge and use it on Claws Mail (desktop) and K-9 Mail (mobile) as for Tutanota I use both desktop and mobile app.
Some other e-mails habits of mine: I use e-mail aliases (ProtonMail plus account provides you with 5) and each alias is used for different tasks (as one for shopping, one for banking, one for accounts etc) and none of my e-mails have my real name on it or something that could be used to identify me. I also highly avoid using stuff that require e-mail/e-mail verification for usage (e-mail is such a pain in the ass tbh) I also make use of Spamgourmet for stuff like temporary e-mail (best service I found for this doing my research, dunno if it's really the best tho, heard that AnonAddy does kinda the same stuff but dunno, recommendations are welcomed)
Browsers/Search Engine: As mentioned, I use Vanadium (Graphene's stock browser) on mobile as it is the recommended browser by Graphene and the one with the best security for Android, for desktop I use a Hardened Firefox (pretty aware of Firefox's security not being that good, but it's the best browser for PC for me as Ungoogled Chromium is still not there in A LOT of things + inherent problems of Chrome as not being able to disable WebRTC unless you use an extension etc) with ghacks-user.js and uBlock Origin (hard mode), uMatrix (globally blocking first party scripts), HTTPS Everywhere (EASE Mode), Decentraleyes (set the recommended rules for both uBlock Origin and uMatrix) and Temporary Containers as addons. I also use Tor Browser (Safest Mode) on a Whonix VM on Qubes sometimes. DuckDuckGo is my to-go search engine and I use DNS over HTTPS on Firefox (BlahDNS as my provider once again)
browsing habits: I avoid JavaScript the maximum I can, if it's really needed, I just allow the scripts temporarely on uBlock Origin/uMatrix and after I'm done I just disable it. I also generally go with instead of (as JavaScript is not required to browse the old client), for checking twitter stuff (although I rarely have something peaking my interest on Twitter) and I use as youtube front-end (I do however use YouTube sometimes if a video I wanna see can't be played on invidious or if I wanna watch a livestream) and instead of other than avoiding JavaScript most of my browsing habits are just common sense at this point I'd say, I also use privatebin (snopyta's instance) instead of pastebin. I also have multiple firefox profiles for different tasks (personal usage, shopping, banking etc)
VPN: I use Mullvad (guess you can mention it here since it's PTIO's recommended) paid with bitcoin and honestly best service available tbh. I use Mullvad's multihop implementation on Wireguard which I manually set myself as I had the time and patience to learn how.
password manager: KeePassXC on desktop and KeePassDX on my smartphone, my password database for my desktop is stored on a USB flash driver I encrypted with VeraCrypt.
some other software on desktop: LibreOffice (as a Microsoft Office substitute), GIMP (Photshop substitute), Vim (I use it for multiple purposes, mainly coding IDE and as a text editor), VLC (media player), Bisq (bitcoin exchange), Wasabi (bitcoin wallet), OBS (screen recording), Syncthing (file sync), qBitTorrent (torrent client) and Element (federated real-time communication software). I sadly couldn't find a good open-source substitute to Sony Vegas (tested many, but none was in the same level of Vegas imo, KDENLive is okay tho) so I just use it on a VM if I need it (Windows VM solely for the purpose of video editing, not the same one I use for gaming)
router: I have an Asus RT-AC68U with OpenWRT as its firmware. I also set a VPN on it.
cryptocurrency hardware wallet: I store all of my cryptocurrency (Bitcoin and Monero) on a Ledger Nano S, about 97% of my money is on crypto so a hardware wallet is a must for me.
I have lots of USB flash drivers that I use for Live ISOs and for encrypted backups. I also have a USB Data Blocker from PortaPow that I generally use if I need to charge my cellphone in public or in a hotel while on a trip (rare occasion tbh).
I have a Logitech C920e as webcam and a Blue Yeti microphone in which I never let them plugged, I only plug them if it's necessary and after I'm done I just unplug them.
I also have a Nintendo Switch Lite as a gaming console that I most of the times just use offline, I just connect to the internet if needed for a software update and then just turn the Wi-Fi off from it.
Other Habits/Things I've done:
payments: I simply AVOID using credit card, I try to always pay on cash (I live in a third-world country so thank god most of people here still depend on cash only) physically and online I try my best to either by using cryptocurrency or using gift cards/cash by mail if crypto isn't available. I usually buy crypto on Bisq as I just don't trust any KYC exchange (and neither should you) and since there aren't many people here in my area to do face to face bitcoin trade (and I'm skeptical of face to face tbh), I use the Wasabi Wallet (desktop) to coinjoin bitcoin before buying anything as this allows a bit more of privacy, I also coinjoin on Wasabi before sending my bitcoins to my hardware wallet. I also don't have a high consumerism drive so I'm not constantly wanting to buy everything that I see (which helps a lot on this criteria)
social media/accounts: as noted, aside from Signal and Element (which I don't even use that often) I just don't REALLY use any social media (tried Mastodon for a while but I was honestly felt it kinda desert there and most of its userbase from what I've seen were some people I'd just... rather don't hang with tbh) and, althoug not something necessary is something that I really advise people to as social media is literally a poison to your mind.
I also don't own any streaming service like Netflix/Amazon Prime/Spotify etc, I basically pirate series/movies/songs and that's it.
I've also deleted ALL my old accounts from social media (like Twitter etc) and old e-mails. ALL of my important and main accounts have 2FA enabled and are protected by a strong password (I use KeePass to generate a 35 character lenght password with numbers, capital letters, special symbols etc, each account uses a unique password) I also NEVER use my real name on any account and NEVER post any pictures of myself (I rarely take pictures of stuff if anything)
iot/smart devices: aside from my smartphone, I don't have any IOT/smart device as I honestly see no need for them (and most of them are WAY too expensive on third-world countries)
files: I constatly backup all of my files (each two weeks) on encrypted flash drivers, I also use BleachBit for temporary data cleaning and data/file shredding. I also use Syncthing as a substitute to stuff like Google Drive.
Future plans:
learn to self-host and self-host an e-mail/NextCloud (and maybe even a VPN)
find something like BurneHushed but FOSS (if you know any please let me know)
So, how is it? anything that I should do that I'm probably not doing?

What I currently use for privacy

So this is what software I currently use for privacy, would like some opinions if possible:
Starting with my cellphone, my device is a Google Pixel 3A XL with GrapheneOS flashed, I have the following apps installed:
F-Droid and AuroraOSS (as my app stores), NewPipe (youtube client), Vanadium (web browser), Tutanota and K-9 Mail (for e-mails), OsmAnd+ (for maps), Joplin (notes), Open Camera (camera), OpenBoard and Mozc for Android (Keyboard and Japanese Keyboard), Aegis Authenticator, KeePassDX (password manager), LibreTorrent (torrent client), Librera PRO (pdf/epub/mobi reader, I don't own a Kindle nor want to own one so I use my cellphone to read), Tachiyomi (manga reader), Signal (for messaging), Vinyl Music Player, VLC, Simple Gallery Pro and Simple Calendar Pro (I prefer them over stock Graphene options) and I also use Electrum and Samourai (Bitcoin Wallet) and Monerujo (Monero Wallet)
I also have OpenVPN (for VPN) and use a private DNS for ad and tracking blocking (provided by my VPN provider)
I have 3-4 PCs, will go over every single one of them:
my main PC is a desktop PC (that I built myself) that I mainly use for working and other tasks.
It runs Artix Linux (basically Arch Linux without systemd), I use UFW as my firewall (denying all incoming and also denying all outgoing only allowing what is useful) and I also use AppArmor Profiles, I disabled IPV6 and SWAP, configured my VPN connection as well on network settings and I currently run OpenVPN on my computer (my VPN provider allows for multi-hop cascade through OpenVPN in which I can create a custom VPN cascade up to four servers, each consecutive hop re-encrypts my traffic and assigns me a new IP address) and I've also set disk encryption on installation (have set in all of my computers)
As for software: I use Mozilla Firefox as my web browser (I set it to always be in private mode, unchecked suggestions for browsing history, bookmarks, and open tabs, I've also disabled the Firefox data collection in settings and block dangerous and deceptive content, I use DuckDuckGo as my search engine, I use Firefox Home as my default as my homepage. The rest of my tweaks were done in about:config (using site tweaks + geo.enabled = false, network.cookie.lifetimePolicy = 2 and as true which are not listed on the site) and the only addons I use are uBlock Origin on Hard Mode and Decentraleyes), KeePassXC (password manager), VIM (use it as a Text Editor and as an IDE for coding), LibreOffice (for working stuff), GIMP (image editor), VLC, qBitTorrent and Tutanota's Desktop Client and Thunderbird (for e-mails)
I also use KVM/QEMU for virtual machines (usually in case I wanna test some distro or use Tails/Whonix)
For my gaming PC (also a desktop I've built myself) I run Manjaro KDE on it, the only apps I have in the system are Firefox (same settings as above), OBS and KVM/QEMU (which I use a Win10 virtual machine for games, there are tutorials on YouTube on how to do so if you're interested). I have the same firewall settings as above, using AppArmor as well and I've also disabled IPV6 and SWAP, I run OpenVPN on it as well as my VPN DNS settings on network settings. I also use different mouse and keyboard on both my PCs and never mix them together.
My other 2 PCs are both laptops, one is a Acer Aspire Nitro I've bought for work (in case I need to work while in a trip or if I wanna work outside etc), it has the same settings and programs as my main PC but I run Gentoo on it. The other laptop is an old ThinkPad that runs Slackware on it, but I rarely use it and this laptop is most of the times not with me for safety reasons.
For some other devices and stuff: I have an Asus RT-AC86U router with OpenWRT flashed on it that I also run OpenVPN config files (this one coming from another provider, I use two VPN providers, on in my PCs and the other in my router), I have a Ledger Nano S as a hardware wallet for both Bitcoin and Monero (most of my cryptocurrency is there, I use hardware wallet for hodling purposes and as my emergency funding) and I have LOTS of USB flash drivers (all of them for Linux Live ISOs purposes), I also have a Nintendo Switch Lite (only gaming console I have, although have not been playing that much on it recently) that I only connect to the internet in case I need to download some updates or play online and after I'm done I immediately disconnect it from the internet.
Some other privacy habits I have are:
I don't own any smart device like Smart TVs (I've been more than 10 years now without watching TV, doesn't even bother me), Smart Fridges or Dishwashers that connect to your internet, ROOMBAS, Smart Home etc, I keep all my money on crypto (and I have a small amount in gold as well, but I rarely invest on it, all my gold is stored in a manual safe here in my apartment) and I only have like, 10 bucks or so in my back account (as soon as I receive any money I just left the necessary in my account to pay bills and put all the rest on crypto, I try to pay everything on crypto or cash), I RARELY use cloud storage, but if I need to, I go with NextCloud and encrypt all my files with VeraCrypt before uploading it, all my VPN services were paid with Bitcoin (I try to pay everything with crypto as previously said) and I never write directly into any website, I usually write my text on a text editor, copy it and paste it on the website (needless to say that I don't use mainstream social media as well)
So, what do you guys think? anything that you would add your recommend me? (before anyone mentions about self-hosting a DNS server using Pi-hole on a Raspberry Pi, I'm actually thinking on doing it in a near future)
EDIT: forgot to mention that I don't watch YouTube on PC on youtube site, I mostly watch youtube's videos on and only use the youtube site for watching live streams honestly. And I also barely go outside with my smartphone (only if I really need to) and I usually keep it away from my computers etc.
EDIT 2: also another thing: I covered all my laptop's webcams with black electrical tape, I have a Logitech C922 Pro webcam for my desktop PCs but rarely use it, and when I need to use it, I unplug it as soon as I'm done with it.

Got hacked, and hacker played a joke on me?

Alright, i am paranoid now.
-I use Ubuntu 18.04, i rarely install software on it, i don't have pirated software either.
-I try to stick with trusted sources for package distribution (Don't think i even added an untrusted one)
-I do not download attachments from sketchy emails, and almost none in general
-I don't remember seeing porn on the PC, very rarely ever did it;
- I am the sole user of this desktop;
I am running clam AV through the whole system rn. Will update if something comes up.
Now, this appeared out of nowhere (gift icon appeared on desktop [for google]), i use chrome browser exclusively and if it was the case of me downloading it, it would appear on "downloads", i think.I don't use any other browser.And i didn't download it... but i would admit the possibility of having it downloaded unwillingly, but again, no record of downloading anything on chrome.
This seemed like a visitation card, or a joke - [After some introspection might be something more serious].My sensitive information is all relative to bank accounts, i have 2 factor authentication on almost everything, but if this a real threat should i have to go through the labor of changing every password?
What should i do?Thanks guys


A suspicious file appeared on my desktop, i didn't put there, only i use the computer;


There is one major detail that i forgot to add as i didn't pay much importance to it. I was given an external HDD to look at , out of curiosity, that came from a friend. His entire company network was affected by a ransomware. As it seems, his backup disks were too. And he handed me one just to look at. I never intended to connect this HDD to my computer with my main OS running
I've tried to peek into it by launching a live Kali session , thought it safer than a VM session.The disk wasn't mounting so i gave up pretty quickly. Now, i did end up restarting the computer, the HDD stayed connected almost until the Ubuntu login prompt appeared, i removed it immediately and didn't think much of it (As i thought this was probably a malware targeting Windows machines).
I might have a time bomb at hands, as i don't know if this Ransomware could be triggered remotely or if it really infected the machine, would it take immediate effect.
I am taking no chances, luckily i keep backups offline every week of important files, so i'll wipe the machine and be more careful next time.
You got to know how to play stupid games, to win stupid prizes . Thanks guys.

update 2:

User u/Frankstwo recommended to run last and coincidentally the last reboot date is consistent with the date of the file creation:
$ lastsousa :0 :0 Sun May 3 16:07 still logged inreboot system boot 5.3.0-51-generic Sun May 3 16:07 still running
The file creation appears as Sun May 3 16:08.
I haven't rebooted the computer ever since.

I am curious if some kind of DMA Attack was performed, because i haven't logged in BEFORE i removed the device from USB port. or could it be any other attack vector....

Update 3: i got hacked!

Holy crap! I rebooted the machine and I got a ransomware! In 15 years of using computers and internet this is the first time i got really hacked (that i know of...)
I keep minimal information on site luckily, i'm very intriged by what's in that HDD but i will toss it out... i'm kind of flabbergasted and dumbstruck . What a dumbass i was...
Never thought it possible on a linux environment though...
To finalize, why these guys always go with Bitcoins? I wonder if monero or ZCash isn't more suited for the purpose...

Fullnode RaspberryPi external HD

Friendly friends, I'm a noob but like to run a full Bitcoinnode on raspberry pi. I barely know linux, so I just used tutorials step by step. Because of one of these I loaded the blockchain on a usb harddrive (formatted for Linux ) with my Windows pc. I also did everything neccesary to install bitcoin full node on my raspberry. How do I make the bitcoin node use the data on the external harddrive? I created a directory like /data and mounted the hd. Whats left?

Running Two GPUs- This is a tricky one.

I'm trying to get a (remarkably unorthodox) multi-GPU setup working with my system. In short, I'm trying to pair an Nvidia GTX 1050ti and a Quadra FX580 on the same Windows 10 system. My motherboard is a Gigabyte GA-A320M-S2H.
The 1050ti is installed in the PCiE x16 slot, and the Quadro FX580 is installed in one of the PCiE 1x slots via a 1x -> 16x riser card(typically used by bitcoin miners). Windows 10 recognizes both devices in the device manager. Yes, I understand the bottlenecks, warnings, and otherwise ridiculous nature of this setup, but I just needs it for additional monitor outputs. Buying a completely new 10-series GPU or new motherboard is out of the budget(already had the Quadro FX580 on hand), and USB-based video cards are too unreliable and underperforming for what we're after. This is what we've tried so far and the results we've gotten:
Here's where things get interesting.
Booting into Linux, both GPUs work with no issues, right off the bat.
Booting into Windows 10 safe mode and running DDU (followed by a reboot back into safe mode) enables both GPUs, and they both work. Which suggests that Windows 10 is definitely capable of operating in this configuration. However, attempting to install either driver for either card (or even just letting Windows do so on its own) breaks the FX580 and enables only the 1050 ti, giving a "Code 43" for the FX580 in device manager.
I'm completely perplexed. Drivers for the FX580 aren't important, as it's just for additional screen real estate, though being able to run the latest drivers for the 1050ti would be nice for best game performance. Is there a way to "lock" the working Microsoft Basics Display Driver to the FX580, keeping it in a working state and allowing the 1050ti to be updated? My friend did this successfully with his personal system with a 1080ti and an old ATI card and it was plug-and-play; both cards worked great and there were no driver issues, so I'm completely stumped as to why this configuration is giving me so much trouble(He is stumped on this problem as well)
Any insight or help would be greatly appreciated!

Number crunching/Deep learning machine needed

I have tried to build my own, but it appears like I've gotten rusty in this. It has also reached prices beyond my expectations. But I want to keep it for about 7-10 years.
What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.
I don't plan to use this for gaming or bitcoin mining. I will process a lot of text from external sources, compute numbers, and train some deep learning models.
What is your maximum budget before rebates/shipping/taxes?
4000 USD / 36000 NOK.
When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.
What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc)
Things I would want:
CPU: AMD Ryzen 9 3950X (or something fast that has 16+ cores; I will run highly parallel jobs) GPU: GeForce RTX 2080 Ti (large memory is preferred) Memory: 32GB (or more) Motherboard: Preferably an X570 with PCIe 4.0 NVMe support. WiFi would be nice, because there is no network cabling around that area. USB-C heads would be nice, but not required. Case: USB-C is required. I prefer white, silvegrey, but black would be fine as well. No disc drive needed. Storage: NVMe (1 TB should be enough for me, I suppose). I already have an SSD inside my old machine. PSU: 850W or higher would be good. I have plans to install another card in that. Fans: I have no idea how many I need, nor where to mount them. Something less noisy would be nice. If water cooling is less-noisy and comparable in terms of pricing, I can go for water cooling.
Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?
If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.
SSD (Samsung evo 850), keyboard, mouse, monitor. Brands of those don't matter.
Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?
Most likely, no. However, it appears like both the CPU and the GPU can be overclocked to a certain extent.
Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)
CUDA and OpenCL support would be required. I already have an SSD. But an NVMe drive is needed.
Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?
I don't like LED lighting. I prefer white, silver or grey cases. Size doesn't matter as long as I can place 2 full size PCIe cards in that. I don't like window, but don't mind if a cheap model has that.
Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?
No. It will run Linux.
Extra info or particulars:
Nothing apart from those.
I would be very happy, if you could help me build something along these lines.

How secure is my plan: I want to generate a long-term cold storage wallet using Ian Colemans tool and regular dice

Hi there!
I have been into Bitcoin for a few years now, but I took a break from the topic and didn't keep up to date with the latest technology. When I was still active, paper wallets were still the hot new stuff!
I do own a Trezor Model T, but I want to be EXTRA paranoid and not trust the hardware wallet to generate a wallet for me. The chances of this are slim, but what if the hardware was modified to generate a wallet that another party has access to?
Now, I want to generate a highly secure long-term cold storage wallet for a relatively large amount of Bitcoin and only rely on myself. I already read quite a bit about the topic, but because of my inexperience I have a hard time understanding just how secure the method really is.
Then I found this video:
He generates the mnemonic by rolling dice and putting in the results as entropy into Ian Coleman's tool. From that, I created a plan that currently looks like this:
  1. How do I use the test vectors to validate Ian Colemans tool and where can I find them?
  2. Are regular dice rolls "secure enough" for this in terms of entropy and the guess of somebody guessing it?
  3. Does it make sense to use some more sources of randomness, like keyboard mashing and data from that I have copied offline?
  4. Can I simply import the generated mnemonic into a hardware wallet like Trezor?
  5. Is the mnemonic (24 words) really enough to restore the wallet or do I need something else?
  6. Are change addresses handled with this or will some spare change be sent to other addresses I (maybe) dont control?
  7. Is there any way somebody could get access to my wallet if I only access it from the Trezor Wallet website and without exporting the private keys anywhere?
Thank you guys for your help, I really appreciate it! :)

Groestlcoin 6th Anniversary Release


Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.





ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.



Main Release (Main Net)
Testnet Release


ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.


Live Version (Not Recommended)



ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).





ALL NEW! – Groestlcoin EasyVanity 2020

Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet.
If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).




Remastered! – Groestlcoin WPF Desktop Wallet (v2.19.0.18)

Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode.
This wallet was previously deprecated but has been brought back to life with modern standards.


Remastered Improvements



ALL NEW! – BIP39 Key Tool

Groestlcoin BIP39 Key Tool is a GUI interface for generating Groestlcoin public and private keys. It is a standalone tool which can be used offline.



Linux :
 pip3 install -r requirements.txt python3 bip39\ 


ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

BTC Node. Need help with Ubuntu and BTC core program. To the Linux experts here in reddit.

The good thing of loosing a post, is that you have to retype everything and this means that you are able to shorten the post.
So. TLDR, I have 2 hdd, 80gb and 320, the second one has only, all the Blockchain info, from another already running node. I am not able to tell BTC Core program that the files are already there so he does not need to download 300gb. After hours of Google and linux forums, I am stuck in this issue. Every time I type "bitcoin-qt" on my terminal, it shows as a first download. Any help will be appreciate.

Full story.
English is not my first language, and this is being typed for second time (please have mercy on my grammar or misspelling mistakes), because I posted the question on linux subreddit nobody give a f..... so I decided to bring it here, posted a short post with the link and the automatic bot deleted because the of the link. I erased both the linux and the bitcoin post, and made a third one new, here, with plain text, copy pasting the info from the linux post. Never appeared on the "new" section of this sub. So hours of typing lost, and here we are.
Old Notebook. 80gb drive, and noob to Linux. Although I have some pc and logic knowledge, installed MINT due to a recommendation from a Bitcoin community, but since I have a friend with an already running node, with Ubuntu switched to this one, just to have the same system.
Once Ubuntu installed, on the 80gb and pc running, I copy and pasted the whole bitcoin folder from my friends pc to my 320 gb. Up to here all was good. But here is the problem

My friend, who does not understand nothing about linux, is owner of a company and has an IT guy who made everything for him, but would not be willing to help me a lot, (just to be good with his boss but right now it is not reachable for me), but when we where on my pc he told me that Linux is very sensitive to ports, in other words, a small usb change, will do a program to loose the path for the files. SO, instead of using the 320gb disk on USB i installed on this notebook second Hdd bay (its an old high end laptop with 2 sata connectors), he was able to set the program and everything went well for a couple of hours, Bitcoin Core program started synchronizing, downloading very little info.

I needed to turn of the pc to move it, so closed the program (waited until bitcoin core program told me was safe to) and turn it off, then turn it on again, and the problem was there, bitcoin core program started trying to download the whole blockchain in the spare 2gb of the 320 gb disk.
So what it seemed to happen is that even when the disk is installed on a sata bay from the motherboard, as I did not installed ubunutu with this disk connected it's route (adress?) is dinamyc and that is why BTC Core Program lost the files and does not recognize it.
After hours of google, linux forums and "askubuntu" i was able to, mount the 320gb disk, first editing the fstab ( i followed the guide in "") by the way. Trying to use VIM editor was a pain, it is REALLY difficult to type something there, and save it without pressing a wrong key. I had to cancel and start over at least a dozen times (plus reading several guides), but still was not able to mount the disk (Actually after following the steps, the hdd (320) disappeared from the GUI). went back, erased, and the did the NANO steps, and I THINK that now the hard drive it is fixed (before, any change,when restarting the second hdd took some time to appear, now it seems that is mounted and to a fixed adress). Well, after mounting the hdd, I tryed to call the bitcoin-qt and the initial download page appear and again tries to download from the initial block. I searched over hours "file association in ubuntu", "program files path" etc etc and the only thing I found is how to set up the desired software to open a file.

For you to understand my mess, when I did the "user:user" thing, I did not understand completely what I was doing, (yes I had to be in sudo) BUT i think I managed to did the correct thing as both hdd are shown in the Ubuntu GUI.

Some additional data is
Both hard drives are formated in Ext4
I have (I think that) a fstab.bak before any changes

I knwo that linux users sometimes ask for details on the system, just tell me the commands and i can run them to stick any info needed.

Thanks for the help in advance.

What if Bitkey but for Monero

I just learned about bitkey, and boy am I impressed. Like my actual point is that I think a critical fatal flaw in the crypto economy and bitcoin network is the reliance on centralized hardware manfufactures whose proprietary closed garden systems and also of course centralized exchanges. I think it's just a matter of time before Trezor and LedgerNano become targets, or some rouge intelligence agent releases to the darknet some tool to crack them or compromise them.
BitKey is a bootable system image based on Debian containing everything you need to perform highly secure air-gapped Bitcoin transactions. You don't need to install it to a hard drive because it runs live from RAM. You just write the ISO image to a USB drive or burn it to CDROM.
I'm a die hard open source linux open system advocate, and I think that bitkey is the right step in the right direction. And my point being, anyone who's a developer could make some version of their own to be audited by the public community. Eventually we would have a handful of publically trusted builds by different developers, and this could be done for the major cryptos, or any crypto, but especially monero since it barely has hardware support.
But the design of bitkey being an iso image on a cd rom or a usb, set to maximum privacy with two computers and a third device that scans QR codes. (on a side note there are security issues with QR codes, so that is one area for improvement).
I'm trying to imagine a world where people can't get safe devices, can't get hardware wallets, and need an open source alternative to compromised desktops. Obviously something as advanced as a linux OS build spread across three devices for airgapping has a learning curve, but UI can increase over time.
We have to remember there are a lot of tyrants in this world who want the monero and btc network to fail, want the fungibility and privacy and cash like nature fail, want to backdoor everything, they want to know if you're hungry, if you need to take a shit, before you even know, Minority report shit, but sadly unironically, and increasingly so.
Windows is the devil obviously, Apple even more so. We need a world moving towards Linux, RVISC chips, raspberry pis. Even the best intentions of cypherpunk and monero are very very vulnerable without the hardware to back it up. So there really needs to be a move towards this.

New wallet set up, is this good?

"Also posted in /Bitcoin but haven't got any responses"
At the moment I am using the blockstream green wallet, which I really like, interface wise etc. but I want more security. I will keep this wallet as a spending wallet with small amounts and have most of the Satoshi's transferred to a "hodl for life wallet". I want to set up an electrum wallet in Ubuntu while offline and delete it afterwards, only keeping the seed phrase. On my android smartphone I will set up a Watch-only electrum to keep track of it.
So here's the plan:
Receiving funds should be easy, just send an amount to a public adress and I can verify it on the app.(will test a small amount)
Sending funds (which will happen rarely), but I will test with a small amount:
Is this gonna work? Any tips, suggestions?
There are probably more secure/advanced ways to do something like this. But although I've used linux/Ubuntu years ago, I'm still a beginner. And regards bitcoin/blockchain just started out getting in depth about a month ago and the more I get to know about it, the more I realise what a legend Satoshi is.
Edit: Another side question, if anyone finds out your seed phrase and gets access to your wallet, but won't transfer any funds, will you find out somebody had access?
Cause I just tried it with green wallet, I installed the app on another phone, used my seed phrase and entered my account. I could still access with my own phone and wouldn't have known somebody has been in my wallet?

The different kinds of cryptocurrency wallets:

The different kinds of cryptocurrency wallets:
Before we plunge profound into the various sorts of cryptocurrency wallets, it is critical to comprehend what cryptocurrency wallets are. It is a blend of a private key and an a public address much like a login ID and a password. The mix of the private key and the public address gives you access to your cryptocurrency and furthermore gives you the alternatives to transact utilizing them.
Hardware Wallets:
The name is very plain as day! Hardware wallets are hardware devices that are worked with a particular reason for dealing with private keys and public addresses. To a great extent, the hardware wallet is a USB-like gadget with an OLED screen and side buttons that assist you with exploring through the interface. Connecting it to a PC and associating with it over local work area applications for different currencies lift the usefulness of the hardware wallet. The hardware wallet doesn't utilize a battery and can be associated with either a PC or a cell phone.
Paper wallets:
Paper wallets may appear to be basic with the classification yet it requires some specialized abilities and elevated level of inquiry from the user. In a typical paper wallet, you print the private keys and the public addresses on a bit of paper and your Bitcoins or some other cryptocurrency on it.
Perhaps the best bit of leeway of utilizing a paper wallet is that it keeps your private key outside the system and that part improves the security.
Desktop wallets:
Desktop wallets are the old fashioned sign of cryptocurrencies. They are installable software bundles that can sit on well known operating systems like Windows, Mac, and Linux.
Outside the topic of security, any cryptocurrency that is not kidding about itself will dispatch their desktop wallets on the primary day itself. Nonetheless, since it is another software which interfaces with the internet, it is critical to follow the essential security estimates like antivirus and against malware software.
Mobile wallets:
Mobile wallets, on account of the mobile telephone entrance and the continuous availability, are the most well known sort of wallets at this moment. They are intended to be anything but difficult to utilize and are compatible with both iOS and Android. Regardless of whether not for an iOS application, you will undoubtedly discover in any event a conventional Android adaptation.
Web wallets:
Web wallets are tantamount to the digital banking interfaces of mainstream Banking. They are constantly associated with the internet and can be gotten to utilizing the web address through programs like Chrome or Firefox. The private keys are held online in the program itself and are inclined to DDOS attacks. Web wallets can either be hosted or non-hosted relying upon the sort of wallet that you use. The non-hosted kind of wallets are prescribed as you are in full control of your funds.
Blockchain App Factory excels in employing disruptive technologies after intensive research and discovering new possibilities every day. Get your own multi cryptocurrency wallet to experience seamless and secure exchange of your virtual currencies from us.

Best Ethereum Wallets

Best Ethereum Wallets
When you start using cryptocurrency the number one problem is to find a secure wallet. In this article, we will introduce the most popular Ethereum wallets.

Hardware Wallets

We start with hardware wallets. These wallets provide offline storage for cryptocurrency. This kind of Ethereum wallet is considered to be the most secure.

  • Trezor
Originally Trezor was developed for Bitcoin. Now it supports more different cryptocurrencies including Ethereum. This ETH wallet will work in tandem with your MyEtherWallet.Trezor is famous for the features that make it very secure. It provides 2-factor authentication, advanced cryptography and the opportunity to check transaction details before you confirm.
On the other hand, there are a couple of disadvantages. Such as the cost: the Trezor wallet is pretty expensive. If you are not a regular user you probably should consider cheaper wallets. Also, it takes time to access your holdings with this wallet.Thus using Trezor as Ethereum wallet may be a little inconvenient if you are a common user.

  • Ledger Nano S
Ledger Nano S is also a hardware wallet. It connects with any computers via USB. The most important feature of this wallet is security. As well as Trezor it provides 2-factor authentication. Aside from this, this Ethereum wallet has a PIN code to secure the device itself and also you can back up your account on the recovery sheet. Ledger Nano S gives users an opportunity to check details of transactions before the confirmation.
The main disadvantage of the Ledger Nano S wallet is the price. It is cheaper than Trezor, but it is still pricey.

  • KeepKey
KeepKey is a hierarchical deterministic (HD) wallet. It is also in the group of hardware wallets. KeepKey supports a lot of cryptocurrencies.The fact that this is an HD wallet allows users to generate private keys in an unlimited quantity. Undoubtedly this adds to the security level. Moreover, with the help of this device, you review and confirm every transaction. You can also set up a PIN code and a recovery sentence to make sure your holdings are secured enough.
It is easy to start using the KeepKey wallet. You need to download a couple of applications. One is to create a wallet. And with the help of the second one, you will be able to connect to KeepKey through Chrome.
Talking about the disadvantages we should mention the price. It is one of the most expensive wallets on the market to use it as ETH wallet.

Web Wallets

The great thing about web wallets is that you can easily access them. All you need is an internet connection.

  • MyEtherWallet
Unlike the most part of hardware wallets, MyEtherWallet is free. Nonetheless, it provides a high level of security by allowing users to store their keys on their own computers. There is no necessity to give any private information when creating a wallet.This Ethereum wallet interrogates with some hardware wallets such as Ledger Nano S and Trezor. Also, this platform gives an opportunity to write smart contracts.
In addition, MyEtherWallet provides automatic back up. So users should not remember about this by themselves.Moreover, it’s possible to get a paper Ethereum wallet by going to the “Wallet Info” section.

  • Coinbase
First of all, Coinbase is an exchange platform. Usually, it is not recommended to store cryptocurrency on the stock platforms. But Coinbase is often considered to be an exception. This platform has a wallet that is suitable for use as ETH wallet. It is easy to use and has an intuitive interface.
One of the major drawbacks of this wallet is that users don’t control their private keys.

  • MetaMask
MetaMask is not just a popular Ethereum wallet. It is a browser extension. It can be installed on a number of browsers such as Chrome, Firefox, and Opera. This form allows accessing your holdings easily.The good thing is that you don’t need to provide personal information for the registration. Also, there is an opportunity to store the private key on your computer.

Desktop Wallets

There are wallets that are made in the form of a software program. They can be installed on your device. Such wallets are called Desktop Wallets.The security level of these wallets is not as good as of hardware ones.

  • Exodus
Exodus is a multicurrency wallet. So it can become your ETH wallet.It is famous for its user-friendly interface. It is a good wallet for those who only start their journey into the cryptocurrency world. Exodus supports ERC20 tokens.Users store their private keys on their computers. This increases the security level. Exodus has a backup feature.
The drawbacks of Exodus are that there is no possibility to add any custom tokens and a small list of ERC20 tokens.

  • Atomic Wallet
Atomic Wallet has a very convenient interface which is suitable even for the beginners. It supports Ethereum and all the ERC20 tokens.The wallet supports atomic swaps. So you can not only have one wallet for Ethereum and all the ERC20 tokens but also exchange them with another user.
Unfortunately, it doesn’t have a hardware wallet yet. So the level of security may not be very high.

  • Mist
Mist is the official Ethereum wallet. So it is a full node wallet. Full node wallet downloads the whole Ethereum blockchain on users’ computers. In other words, it downloads all the data about the ETH network. This type of wallet makes any user a full-fledged member of the blockchain.
Mist has developed the way to allow users to interact with their ETH storage easily. It is free. Users don’t provide private information during the process of registration. The only way to access your wallet is to use a password. Your private keys are stored on your computer.The Mist wallet supports smart contracts.

Mobile Wallets

Sometimes it is more convenient to use a mobile wallet, which can be installed on your mobile devices. This type of wallets provides quicker access to your storage wherever you are. Mobile wallets are easier to use than desktop ones, but it is riskier.

  • Jaxx Liberty
Jaxx is free. It supports a lot of cryptocurrencies including ETH. It can work on different platforms such as Linux, Windows, and OSX. There is also an extension for Chrome browser. The interface of Jaxx wallet is simple and good to use.
However, the security of this wallet raises some questions.

  • Coinomi
Coinomi is an Android app. It is easy to use and supports a wide range of cryptocurrencies. With this wallet, you don’t have to think about backup. Coinomi has a feature that helps you to keep all the information. It is secure enough. Your private keys are nowhere but on your device. Coinomi protects the user’s identity when they sign up.
Unfortunately, so far there is only an app for Android.

Paper Wallets

Paper wallets allow printing private keys on paper. And this printed document is used as a wallet. These wallets are not that easy to access. Although the level of security is relatively high.

  • ethaddress
In case you are looking for a way to store your ETH in the most secure Ethereum wallet, but you are not ready to pay for a hardware one, try ethaddress. This wallet is free. It provides a high level of security.

The core of this key-generating wallet is 99% identical to the well-considered of all, it’s necessary to download this website from Github, unpack and open the index.html file directly from your computer. The code version control allows to significantly simplify the mutual verification of the executable code. For more security, disconnect from the Internet at the time of creating your wallet.

How to keep your wallet in security?

Whatever wallet you choose you want it to be as secure as possible. Here are some ideas on how to achieve this:
  • Choose a wallet that suits your requirementsAll wallets are aimed at different goals and ways to use. Some of these wallets offer high security, some provide you with easy access for fast trading. Therefore, you should choose exactly what suits your needs best.

The best Tezos Wallets

The best Tezos Wallets
Tezos is a decentralized blockchain that simplifies formal verification, a method that mathematically proves the accuracy of the code controlling transactions. The Tezos blockchain has its own cryptocurrency called Tezos (XTZ), a cryptocurrency with two main functions – a self-administration system and the ability to form launch contracts using its own programming language – Michelson.
If you decide to convert your fiat savings into Tezos or exchange other cryptocurrencies for XTZ, you may have to make a choice among reliable wallets for this. In this article we will look into the best Tezos Wallets so that can help you understand them better.

Hardware Wallets

Hardware wallets are not liable to spam, viruses, phishing attacks, or malicious of the system. Moreover, they provide a high degree of protection to the private keys. Below is the list of hardware wallets that can be used for XTZ.
  • Ledger Nano S
Nano S is a hard wallet from the product line of Ledger, a French manufacturer company. As all other Ledger products, Nano S traditionally looks like a USB flash drive.

How to keep your wallet safe

A cryptocurrency wallet can be regarded as a regular wallet with money, but it has advanced features, which increases the level of risk. Simple rules will help prevent the loss of your own savings:
  1. Do not store large amounts for long periods on wallets that do not provide full control. It is better to store large amounts for a long time only in wallets that provide full control over the private key and, accordingly, over digital assets. This will help protect your coins against fraud and cyber attacks.
  2. Encrypt information and back up private keys. In case of reinstalling the PC or the occurrence of force majeure situations, this will help to restore access to the wallet quickly.
  3. Store secret keys on an offline device. It is preferable to use a platform that is not accessible for hacking via the Internet.
  4. Use reliable antivirus software and update it regularly. This will prevent the leakage of personal data that hackers can use to crack passwords.
  5. Register several types of wallets. It will allow you to distribute your funds and use the most suitable wallet depending on the situation.
If you use your Tezos wallet wisely and do not neglect the precautions, the risk of funds loss will be minimized.

A tutorial for Tails linux, to stay safe on Internet.

I'm not so sure this will be a help or not, quite sure that official guide is more reliable than this. anyway that's what I have here. If this article contains any kinds of misleading or error, please let me know in the comments.
A tutorial for tails linux, to stay safe on the Internet.
In today's circumstances, it's good to put more effort on maintain a low profile on Internet, or atleast learn how to do that.
If you already have a computer at home, you need to consider to use Tails linux if safety is what your concern about.
Access to then follow download instructions.
The idea of tails is, it will anonymize your entire connection on Internet by using Tor network. So no one will discover your identity without lots of effort.
Not only that, once you do shutdown your device, it no longer holds any information. That means, other one can't find any evidence from your device.
Also if you still want to storage some text on tails, The easiest way is hide that in online email account.
At first, open text editor that preinstalled in tails.
Then, follow the instruction to encrypt your text by passwords and paste it on email account through tor browser. Do not use that account to communicate to others, just keep it in secret.
If you are about to send messages through email, this instruction could be handy. You needs to learn about PGP first, tho.use XMPP is the either easier or safer plan.
You can encrypt other type of files by using Archive manager(give a right click on the file), but the computer gets freeze by that occasionally.
I strongly recommend to use Veracrypt hidden volume instead of build a Persistent storage feature, or LUCKS encrypted drive for linux that available on tails for both send/storage purposes.
In that way, you'll get two of passwords for one encrypted storage. If you are forced to reveal your password by others, you have a option to reveal a fake one.
On top of that, if you use another USB for that purpose, you don't have to slow down Tails itself. Persistent storage is tends to be fragile, I occasionally toast an entire data during excessive use. https://www.veracrypt.fen/Hidden%20Volume.html
You need to use other OSs for create new volumes. Linux is safer than windows I guess, but it takes an effort.
IIRC, you should check "I use hidden volume" radio button during type the password. Otherwise your hidden password doesn't simply work. Don't get confused by that.
Not only that, Tails has the Mac address spoofing function by default. Mac address is the unique identifier for your device.
That function also increases anonymity on Internet. it's important when you go outside because even if you killed GPS function on your devices, it still leave a Mac address on wifi router or 3G/LTE cellular module nearby. So someone still can trace your location.
Also just in case if your government decides to not allow you to connect tor network, you should read this article first.
But if every each of instruction seems failed to helps you, bring your device(with Mac address spoofing function) outside and connect to the Free wifi.
It's relatively safe since either of wifi or device doesn't leave the information that directly leads to you, but be aware on surveillance camera nearby. don't stay there too long, or use one spot too frequently.
I know laptops is too cumbersome to carry around, you have a option to choose something like a windows tablet, a stick pc along with touch screen or a Tv box. not sure on which kind of stuff do the best job unfortunately.
For communication, you need to build the safest/robust assembly point on Internet. The very best option available is XMPP Pidgin chat client.
It's pre-installed in the tails. As you expected, you can start a group chat.
There is couple things you can't do on Tor network or tails Linux.
First, you should read these articles.
Since tails is lots more robust than Tor browser bundle on windows, you can ignore the most of issues in Tor browser. Still you have to aware the risk on this.
Not only that, couple of things is getting harder to achieve through Tor.
At first, some website like Twitter, Reddit or YouTube tends to reject to create an account. If that was just a couple of exit nodes, maybe restart the browser might do the trick.
But if entire exit nodes are rejected by provider, Web based proxy gives you a chance. If that doesn't work, I'd say you should find someone who will to post your messages on viral media.
Secondly, even if you using tails, thats not means you can pay for something anonymously.
If you need to use paid Web base proxy or whatever you want, it's also safer to use anonymous cryptocurrency such as Zcash or monero. not sure how safe are they, pre-installed wallet(Electrum) only supports bitcoin. so you need to use web based wallets.
Or if someone donated a bitcoins to your anonymous wallet, it's safe to use that one through Tor.

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B


This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:
The updates
If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.





This video shows how long it takes to start Reddcoin Core.   TL;DR:


Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.
