if you have more than 2000$ in crypto you absolutely must own a hardware wallet. I recommend a hardware wallet designed specifically for crypto like trezor which also integrates with metamask. Even if someone could sit on your chair, open your PC and have your metamask unlocked, they still can't transfer a single sent without the hardware wallet.

Love the "something is better than nothing" spirit—and sharing the source as a `.txt` so anyone can host their own is awesome. Splitting the keyspace across your phone's cores and verifying it on the old solved puzzles is a really solid way to test things out. Funny enough, I had the exact same thought about those random key-checking sites—they blindly pick random keys and forget everything the moment you close the tab. That’s what pushed me to build **PUZZLE.GRID**([https://cpaawj4efh0kdbzl1ht5d1w4.macaly.app/](https://cpaawj4efh0kdbzl1ht5d1w4.macaly.app/)). Instead of pure random guessing, it uses your payout BTC address as a lightweight account to log every completed chunk of the keyspace. That way, you never scan the same range twice—even after a refresh or reboot (each user keeps their own isolated search space, so it’s not a shared pool). It also generates a quick share link for your address, so you could run it on your ZenFone and a PC at the same time, and both devices will automatically work on non-overlapping chunks. It runs via WebGPU when supported (with a CPU fallback for mobile) and includes a small demo range so you can watch it actually hit a target key, just like your solved-puzzle tests. Keep building—tinkering with this stuff is a super fun rabbit hole!

I had a similar epiphany a few years back when bitcoin properly exploded in value. When I was a teen and bitcoin was still new I played around with it and had maybe 50 in a wallet on my childhood PC. I remembered that and frantically drove to my parents house where it was, and took it home. Only to shortly remember that I had wiped it when I left home as we were supposed to give it to a younger cousin for a present that never materialised. Gutted.

Thanks for the critical breakdown. I completely understand why it looks like "movie magic" at first glance, but this architecture is actually based on established cryptographic principles like Visual Secret Sharing (VSS) and hardware-enforced isolation. Here is how these specific flaws are technically mitigated: 1 & 2. The "Hot Wallet" & Initialization Myth: The initialization doesn't happen in a standard hot environment. The app on the phone/PC acts merely as a gateway. The true entropy (randomness) and the permutation matrix are generated inside a CC EAL6+ certified Secure Element chip via a hardware TRNG on the USB itself. The private keys are never exposed in plaintext on the host OS. Processing happens strictly within the phone's TEE (Trusted Execution Environment), such as Apple's Secure Enclave or Android StrongBox, which is completely isolated from malware on the main operating system. 3. The Backup Solution: Backup is a 2-of-2 model. The scrambled "pixel soup" (the mesh) is locally encrypted via device biometrics and backed up to your secure cloud (iCloud/Google Drive). For the hardware side, you use a "Hardware-to-Hardware" (H2H) protocol to securely clone the permutation map to a second "Twin" USB device using factory-embedded Attestation Keys. No 24 words on a piece of paper for a thief to find. 4. "Anyone with my device and computer can steal it": No, because the app requires local device biometrics (FaceID/Fingerprint) as the final green light. Even if an attacker physically snatches both your laptop and the USB key, the app will not initiate the session or stream the map without a valid biometric scan. 5. How a pet photo keeps it secure: The photo itself isn't the security; it represents the underlying high-entropy data matrix. When combined with the hardware TRNG's cryptographic "salt" during setup, the pixel data becomes a mathematically unique secret. An attacker can't just download the same dog photo from your Instagram, because they lack the specific digital salt embedded in your unique mesh. 6. Sniffing the hard drive or USB bus: The data stored on the hard drive is just the scrambled mesh. Without the permutation map inside the Secure Element, it is mathematically impossible to reconstruct. Furthermore, communication between the USB and the TEE uses end-to-end encrypted sessions (e.g., Diffie-Hellman key exchange) over the USB bus. A hacker scraping the hard drive or sniffing the USB-C port in real-time will only see encrypted noise. The "fancy UI" of the pixels flying into focus isn't just for show—it is a visual confirmation for the user that a successful, un-tampered 2-of-2 cryptographic handshake has just occurred in the secure enclave.

I made one using Gemini AI before, it was working nicely, but several features were still buggy. Gemini (or another AI) will usually program your bot it so it uses the best trading practices so if there is a crash like right now it’ll act accordingly, same for sales. You just need to learn a bit how to make your own server with nodeJs, host it on your PC or on a VPS. If you don’t know anything about programming, it’s better to use the Take Profit / Stop loss system of your app. On my side, I stacked all the cryptos I had (I wanted to test) and couldn’t remove them before 7 / 14 / 21 / 30 days, and while it was stacked everything crashed. I lost the 50 euros I managed to gain in one month T\_T Now I just wait for the value to go back up again.

>  You can't store it yourself without knowing a lot about tech No? I mean, define "a lot." You have to know how to download and install a program on your computer or phone, but that's about it. Most cryptocurrency wallets are dead simple to use; You don't even need to touch the command line for most of them. Sure, maybe storing large amounts of cryptocurrency *safely* (i.e. on a separate airgapped system) is a bit more difficult, but even having a wallet on your main PC is still an improvement over keeping it in an exchange. People are just lazy and don't understand the point of cryptocurrency, so they leave it in exchanges which create a single point of failure.

Nobody wants to suffer losses especially if on table are savings for future retirement periods. I think that it's not possible to become own bank and keep private keys safe at own. First of all if quantum computing and AI are currently at development phase and if the become more powerful then average crypto holders are defenseless because it requires significant amounts of investments into cyber defense. Yet we all know how expensive are computing components like RAM chips, CPU's and even SSD disks. And these components price is till growing. PC component market is sold out to satisfy AI companies demands. And at the end average person just can't permit to build computing shield. The only thing what it's possible to do is keep private keys offline but if AI ever will be able to derive private keys from public keys then offline keeping does not help at all. In conclusion I think that for average person the best outcome would be if the big tech companies see that they have lost control over AI and then will be forced to shut them all down. Otherwise they will lose more and then it will be end of the capitalism like we currently know it is.

I started mining bitcoin in 2012 on my home PC, fell in love with it, ended up doing illegal stuff to get more of it and went to prison. But I've been around crypto since 2012. I've come to believe that crypto is no different than everything else in this world, a scam. I've seen thousands of posts just like this and I lost 145 btc in a scam in 2016. Long story short I ended up with nothing due to my own stupidity. These stories are heartbreaksing. I spoke to another victim of the fake HFT scam i got scammed in and this woman was 70 yo, she put every dime she had into it, even got a loan on her home and maxed her CC's out. She was talking about suicide, a 70yo woman who worked her whole life, raised kids and saved for a retirement and poof, gone. I think they should give scammers the death penalty.

Theoretically it's possible that also any new USB drives and SSD drives can be injected with some kind of backdoors if AI gets in to the manufacturing site plants where chips are installed onto PCB's. There are rumors that Binance case was possible due to the large scale (29 million computers affected ) SSH backdoor injection by AI extensions that made possible to exploit one employee's laptop/PC. So nothing is now granted unless the device (no matter of it's type or usage function) is completely disconnected from the internet. You may buy brand new Smartphone, or even peripheral devices like a new mouse for your desktop PC and you don't even know that it was already compromised at assembling phase in the manufacturing site. AI music video "Claudia is going take your private keys" for me is a prediction or warning of something more dangerous coming on because it's not possible trust anything anywhere. It's not about private keys only, it's about security and safety of any kind of systems and public services-in other words seems like stakes are going high where it would be also question of life and death (If AI compromises first responders ability to react before it's too late).

If several wallets with different seed phrases got drained at the same time, the problem is almost certainly your device, not the wallets. Infostealer malware or a malicious browser extension can grab keys from multiple wallets in one go. Move whatever’s left to brand-new wallets, but only set them up on a clean device, because seeds generated on an infected machine will just get drained again. Scan or fully wipe the PC, remove any extensions you don’t use, and change your email and exchange passwords.

That clears things up. You likely have a virus of some kind on your phone. This means that it's likely a remote administration tool (RAT) and they can likely Livestream what you can see on your screen, log what you type, control your device remotely, and likely they automatically saved all of your passwords as soon as you were infected. They likely have snooped through all of your files and photos, looking for any seed phrases or private content that they can potentially use against you. You're going to have to factory reset your device ASAP after backing up anything important (the phone may now also infect your PC, so I recommend emailing files or storing them on a cloud storage). What phone do you use? If it's old enough, like the Note 20 Ultra, you will no longer be getting security updates, making you extremely susceptible to something like this.

**1. Never send life savings from a hot machine.** The moment you had >$1k in Bitcoin, the rule is: hot wallet is for spending money, like a pocket. Cold wallet / hardware wallet is the vault. You kept 10 years of savings in the pocket. Malware only needs to win once. If you had sent FROM a hardware wallet, the receiving address would be shown on the hardware screen itself. The malware on your PC can't change what the Trezor / Ledger / Coldcard displays. **2. Verify AFTER every change.** You verified before. The attack happens after you click RBF. The rule: **What you see on the computer is not what you sign. What you see on the signing device is what you sign.** Before you click "Broadcast", you must re-check the full address on: * the cold device, or * at minimum, re-copy from your watch wallet and compare the middle characters, not just first/last 4. You said it ended the same - hijackers generate vanity addresses with same prefix/suffix. **3. Small test + different flow test.** You tested hot -> cold small amount, and cold -> hot. You didn't test the *exact* flow you used for the big amount: hot -> cold -> RBF bump. Malware often allows small amounts to pass to build trust, and only swaps large amounts. Correct test: Send 0.85 as: * 0.001 with RBF bump * then 0.849 Or send in 2-3 chunks, not 90% in one tx on vacation day. **4. Clean environment for the big move.** First day of vacation, on your daily-use laptop, rushing to enjoy vacation = worst time for a migration. The safe way: * Boot Tails offline, create cold wallet * Wipe / reinstall OS on hot machine, run Malwarebytes / do not install anything else * Or use a separate clean laptop that has never been used for browsing Clipboard hijackers come from pirated software, cracked games, fake driver updates, Chrome extensions. Most people have no idea they are infected. **5. Use address whitelisting / payjoin.** If you had whitelisted that `bc1qnjtc...` address in your watch wallet, or used a hardware wallet that locks to known addresses, the wallet would have warned "unknown address".

It's not that complicated, he just made it seem very life or death. You can hold your crypto in your own wallet on your PC/special devices OR you can have Binance hold it for you. If Binance is holding it for you, they might get hacked like you saw today. If you're holding it for you, your PC /device night get hacked. So people buy special devices that all the do is hold crypto, then they hide them. However if you're bragging about holding a LOT of crypto someone might come to your house and beat you up for it. Similar to how they might if you brag about holding a lot of cash under your mattress.  So, best advice is don't brag and keep it in a special device. (They're called hardware wallets if you wanna google it.) Hope that clears it up!

It does take some time to understand though and for sure is a barrier for many. Unsure what to say as while it is way more convenient to trust a central authority or third party company’s wallet, they are going to increasingly become targets for hacks along with anything Centralized of value.

I mean the point of a hardware wallet is specifically to allow you to use it on a potentially (or definitely) compromised computer and it doesn't matter right? Its absolutely miles more secure than a PC alone because it doesn't expose your private keys at all no matter whats going on with the PC itself. So that leaves the only way to be targeted is if someone physically obtains your hardware wallet and somehow extracts the private key, which yes has proven to be possible, but usually at incredible effort and expense, especially if a passphrase is used. But really for an average user who has a wallet stuck away in a safe spot this is a super unrealistic attack vector and kinda in a different category of security in my opinion anyway. I'm not personally weighing up crypto wallet choices based on how likely I am to be burgled or how secure they are during a robbery etc. There just isn't a comparable way to safely use a hot wallet than with a hardware wallet. Paper wallets are fine but impractical. Hot wallets like you're suggesting are many orders of magnitude more risk, and I think a hardware wallet exposing private keys from a software attack is just very out of the question too. I've not heard of any way this would be even slightly possible.

Presumably at least one of those devices is their phone or PC. Also, there are options like temporary keys on a Jade where you load the seed only to sign and then it forgets them, so if they are most or compromised they contain nothing. Also, with multisig, even if every device is compromised, someone has to connect all your epubs and figure out which ones to use and how they are signing. The coordination is more complicated than just "the devices are compromised".

I wouldn't use BitPay if I were you. BitPay is an anti-bitcoin company. BitPay supported the S2X attack on Bitcoin back in 2017. BitPay refuses to support SegWit.

Yeah 100%. I invested a couple of thousand GBP in late 2013. I have sold some on the way, bought a miner, mined a few, sold a few and still have a couple. It's a six figure sum still but I am getting fed up with all the risks of theft, scamming etc. I run a full node wallet and recently my hard disk started to error. I bought a new PC and just the differences in versions of wallets and data versions was a drama. It's taken me a week to get my stack in a movable/tradable state and there were times that I thought I may lose access. Don't get me wrong, I've done ok over the past decade but sometimes its a pain in the arse. Fortunately, I'm as old as dirt so it's only a small part of my net worth otherwise I would have been out by now. Will it go to the moon? Maybe but actually nobody knows!

If people had put their coldcard or ledger in a 2-of-2 with an ordinary online malware-ridden windows PC, they would still have their money today. Multisig this way is great for protecting against supply chain attacks, RNG attacks, bugs, zerodays. It's the same physical security as having a single sig but vastly better cybersecurity. A big benefit that nobody talks about is with 2-of-2 (or any N-of-N) you dont need to store the descriptor. The 2 seeds alone are enough. Yes there are ways to backup the descriptor but they all suck. With 2-of-2 you only need to backup the two seeds and nothing else. How many people even realize that to recover a 2-of-3 you need two seeds and **the third pubkey**. If you cant get the third pubkey you've lost it all. You can have a 2of2 with one key on a hardware wallet or airgapped laptop running Electrum or Sparrow, and the other key on an online wallet on your main desktop or phone.

Your key shouldn't be on your PC... that's the whole point of a hardware wallet. The AI shouldn't have any ability to get the key. But, yeah, the Ledger attack was unique, in that hardware was added to steal the key right from the screen that displays it to you, and then transmit it. AI can't do that, but specially designed hardware embedded in a tampered device can. So, where you buy from matters, as you greatly increase/decrease the risk of a compromised device.

I have said this for over 10 years now. Rather then bitcoin meaning with heat as the byproduct it makes much more sense to heat with bitcoin as the the byproduct. If I had enough capital I would design a very effecient warm water boiler for constumers and then sell it a little bit under the price of my main competitor, even if that meant not making a profit on it. Why? Because my boilers would heat by mining bitcoin, after all a PC that draws a 100W also outputs a 100W of heat. Exactly the same as a 100W heather. And my boilers would have a 4G chip in them to connect to the miningpools. That way I am mining Bitcoin for free on the electricity of the people that bought my boilers .... but without stealing from them! Every time somebody buys a new boiler, I get more hardware. Ofcourse the only flaw in this plan is the price of the Bitcoin mining chips. But the day will come where the hardware no longer depreciates so much and new Bitcoin miner is good for 10 years. Then such a boiler/mining plan becomes feasible, if 2 years of Bitcoin mining is good for paying of all the hardware that last 10 years. Regardless, with how much electric heating we do in the world ... you know all the buildings in winter , and the outdoor swimming pools, etc etc. With all the heating there is really no need to waste 1% of the world's electricitry on Bitcoin mining. We can just heat and mine Bitcoin as the byproduct instead of the other way around.

No. Those two are really all you need. Who cares what the UI looks like? No hardware wallet is better than these. These two are more versatile, reliable, and secure than any hardware wallet. As far as I know, no hardware wallet offers the same capabilities—such as Lightning Network management, multisig, UTXO management, fee control, etc.—as these two. You want "hardware"? Then turn it into hardware. Find an old PC you have—kept completely offline—and use Sparrow; then you can have Electrum on your regular PC just for withdrawals. No, you don't need to buy a hardware wallet.

Hardware wallets are IMHO really great addition to security, the problem is, people jump on the first one, some rando on the internet mentions, and these people end up using a shitty device like Ledger or Tangem.

Online banking is a giant target that gets hit all the time. But they spend big money to keep your accounts safe, with firewalls, 2FA, fraud alerts, lockouts, and even deposit insurance that the banks pay for. Hardware wallets are relatively cheap consumer grade products. For a couple hundred bucks and if properly used, they do a whole lot. Many are open source, inviting copycats. Coldcard's efforts to protect their work (which they allegedly heavily borrowed from someone else too) has lead to them making mistakes, and their downfall. And it didn't stop Passport wallet people from basing their product on Coldcards. And all that is a good thing, making these special purpose devices more accessible to people with multiple competing offerings. I don't see myself buying a $25,000 crazy blackbox with MPC and time locks, and multisig, and NFC + eye scan, and fingerprint reader. But a $250 device that generates keys and lets me sign without exposing them.. pretty nice deal. Hardware wallet itself is not impenetrable, and likely cannot withstand physical attacks. If lost or stolen, it's best to consider it compromised, recover elsewhere, and move everything to newly created wallet with all new seed. I do not buy them believing they will securely store and defend keys forever. Safe storage is on me. And adding some entropy is also on me, with dice or passphrases, whatever. But I do trust them to sign a transaction without revealing the keys to my PC. That's what I want it to do, and I have to assume it does. As for the world moving at a fast pace, I do upgrade my wallets over time. I did have a Coldcard MK3 and it was fine, until it wasn't. But by the time the bad entropy theft happened, MK3 was 3 years without firmware updates, and guess what mine did. It was collecting dust, empty, because I've moved on from a product that reached its end of life. And that probably saved my ass, who knows. I will keep buying newer and better hardware wallets, to support the companies that make them so they can continue to improve and release new products, and to protect my coins in newer, better, more usable ways as the tech and UI and safety features get better. People upgrade $1000 phone every 2-3 years. It's not a huge leap that people can also buy a new $250 device that keeps their btc safe on about the same schedule. Learn how to use it properly, and stay at the industry's pace, and that's it. In my anecdotal one person experience, never lost any BTC, and very comfortable using my hardware wallets, kinda regularly, maybe once a week or more.

ooof this is terrible advice. Yes, in theory you can make a really good hardware wallet IF you REALLY know what you're doing because you need to build the right software, update it for continuous security risks, know how to do encryption to protect your key, and more importantly know how to interact online safely which is the tricky part. But you will still have one flaw you'll need to work on. There is a reason hardware wallet have their own integrated screen separate from your PC and online app, so you can verify if the software is compromised and if there is any spoofing.

No, a iPhone is a different architecture than amd64 PC. Your phone doesn't have to be connected to the internet. It doesn't even have to be on, and you can use Faraday's cage. 3rd paragraph is just imaginary problems, when you assume you use that spare phone as phone, and not as just wallet. Ofc you set up your phone accordingly to that use case. If you want to transmit tx, you have to connect to net anyway at some point, even if you're airgapping to PC. Infinitely more secure than hardware you can't verify. Hardware wallet is against basic "don't trust, verify" principle, but y'all got finessed into thinking that it's somehow good setup by shillers and podcaters (Ledger, Cold card, etc). Spoiler, it's not unless you use at least 3/5 multisig. And even then, like I said, y'all lack technical know-how to verify if hardware does only what it is supposed to do.

A PC that was made before 2007 that you physically disable the network card on with old linux and Elektrum software where you check the GPG signatures against as many possible sources you can find. Then when you are alone with zero electronic devices around and your internet shut down you have this PC generate your seeds. You write them down on paper. And then you never update. This PC will act like a hardware wallet. using qr codes or a thumb drive you bring a unsigned transaction over from your laptop or desktop that is connected to the internet. You sign them on your offline PC and then bring the signed tx back where it can be broadcasted. Same as a hardware wallet but because the hardware is from before 2007 you can 100% know it was not tampered with to try and steal Bitcoin. And on the software side you use software at least 2 or 3 years old and you verify the signatures againt 20 or so different sources to make sure it's legit. Now you can be 100% sure the software wasn't tampered with eithere. And then you NEVER update. Imagine Trezor or ledger the company gets hacked and the hacker publish a new firmware and then you update. Boom, coins are gone!

Find a desktop computer that was build before 2008. remove all network capabilities, if it has a lan card on it, physically sabotage it. Find a good and trusted source for the hashes of older versions of linux mint or any extremely popular linux distributions. Use a thumb drive to install linux on it. Download Elektrum, check the hash and find the PGP keys of the developers and quadruplle check them against as many sources as you can possibly can. Once you are absolutely sure you older signde versions of a popular linux distro and Eletrum have both installed on this offline desktop PC. Then it's there that you have that machine randomly come up with your seeds. Make sure you are alone in the room with no phones or no electronics nearby other then the desktop PC and create your seed and write them down on paper. Copy the xpubkey to your thumb drive and install Elektrum also on your online PC. Import the xpubkey there, now you have a watch wallet. You can see but not spend. Now when you need to make a transaction you can make it on the online computer but it's not signed. Save the unsigned tx on your thumb drive and sign it on the offline pc. Then bring it back to broadcast. Make sure the offline PC has a bios password, has a good strong linux password and uses an encrypted partition! (extremeley important). Or if you already have like an trezor model T for many years and you NEVER HAVE UPDATED THE FIRMWARE AND NEVER WILL, you are also safe.

I think one good added level of security is to create your wallet first and then import it into your ledger/trezor. The reason is that most compromised devices are designed to generate predictable wallet addresses that attackers could then drain later. Importing an existing wallet protect you from this sort of attack. Of course a much more sophisticated compromised hardware wallets could - in theory - send the attacker your wallet keys directly so this is not fool proof but it helps. Also there is of course the risk that the software you use to generate wallet key or the PC running the software are compromised. so you decide what is best for you

Soooo much shit has already happened with ledger that if you still use them or bought them after I can only conclused that getting your crypto stolen is a kink. Fuck it I don't even fully trust trezor either, I have a model-T I bought years ago but the bulk of my Bitcoin is on a old desktop PC that was made before 2007 without any network capabilities running linux mint and electrum. on my normal PC I use electrum to make unsigned transactions then put those on a tumb drive and sign em on the offline pc then broadcast on my online PC. Since I have had that PC from before satoshi invented Bitcoin it can't be compromised and I verified all the PGP keys of the bitcoin software I installed. Been using it since 2013 and not gotten hacked yet, the most Bitcoin that was ever on there was maybe 300 or so. So I must be doing something right ... But yeah if you have an old enough trezor you DIRECTLY bought from trezor and you also set up a new seed and you NEVER update it then you are probablly safe ... still it's not impossible somebody intercepted it before it was delivered at your house ....

At the start of every course I would set up a Gemini gem designed to function as an expert in that course's subject. If you're not familiar with these, a Gemini Gem can be considered as either a custom mini-agent or a persistently prompted LLM wrapper, depending on whether you go by Google's marketing definition or the technical definition. It's easy to set up and there are tons of YouTube videos on the subject. It's simpler to do it on your PC rather than on your phone.  I would use Gemini's Pro model, which, if I'm not mistaken, is available to students at a discount these days. It's way more effective at complex tasks (like tutoring a student) than their Flash model. I would give the gem a title and a short description, and in the gem's instructions block I would tell it: \- What role it was performing  \- What skills it was an expert in \- What tools it was an expert at \- What our objective was \- My personal preferences on how I wanted it to perform its task  As an example of personal preferences, I would always include the instruction to keep a professional tone and avoid any unnecessary "back patting" and encouragement. I'd upload to the gem whatever documents I thought would make for a good knowledge base. If I could get a digital copy of the course's textbook, I'd upload that. Including the course name and number, along with the school I was in, often made the gem even more helpful. Sometimes I would get Gemini to help me write the gem instructions.  The result was an effective tutor and study partner that was available 24 hours a day. I passed every final on the first try.

your wallet might be drained by a virus. You might have installed a RAT hidden in some other software, and it has access to all your stored logins and automated logins (when they don't have 2FA), if you have a GPU it can be used for silent mining, and your IP can be abused as a proxy for hacking, bot traffic or carding. If you ever used cracked software or untrusted apps, and are not sure if your device is clean, it is a good idea to format that PC entirely. In that case, the lesson here is to never use apps with possible backdoors on the same device as your bitcoin wallet. A hardware device just creates an air gap so every transaction needs to be verified manually.

For the offline PC, I would use a very minimal OS with no network stack at all, rather than a normal Linux installation with networking disabled. It should run from USB, stay in RAM, and be stateless. Ideally, there should be no Wi-Fi/Ethernet support in the OS in the first place. On the online PC, I would use Sparrow as the watch-only coordinator. It is quite generic and works with many different signing setups. You can then move PSBTs between the two machines using USB or QR codes. There are some open-source projects taking this approach. Worth looking into.

Sparrow's the usual pick for a dedicated airgapped box now: Bitcoin-only, clean PSBT signing, real coin-control. Electrum still works and is lighter, just an older feel. On the seed, "never enter it anywhere" is really about online devices and websites. A permanently-offline machine is safer, but a general-purpose PC still writes to RAM and disk, so a dedicated hardware signer where the seed never touches a computer is the cleaner setup.

Yes, which is why most people do this in an environment that has a smaller attack surface like a HW wallet and if you don't than that is why I asked you that long list of questions at the start >Im not storing the seed or the phrase in the pc With your original plan you would be. The seed would be encrypted in your wallet and the extended passphrase would be typed into the PC when you decided to send a transaction or make a PSBT >I understand once you generated a seed you cant just add a passphrase later. Incorrect . You can add an extended passphrase at any time to create a new wallet >And wouldnt making up your own words for a custom seed be more secure? That is the worst idea. Humans are horrible forms of entropy. The words need to be random. All extended passphrases should ideally be created as explained with dice or other means to create sufficient entropy >I thought the seed was just a way to access a certain part of the blockchain that made you put money in or out Most wallets use hierarchical deterministic (HD) key derivation after bip32. This means you have **Backup Seed words (BIP 39 or other)** consisting of 12-24 words that can than recover **Master extended private key (xpriv,ypriv,zpriv)** Which can generate many private keys **Master extended public key(xpub/ypub/zpub)** Which can generate many public keys As of which from the public keys many Bitcoin addresses can be derived from.

You really should look into SeedSigner for a truly air gapped signing device. A PC does not make a good wallet. A PC makes a great node server. Use it for that. PC for your node, Sparrow for your software wallet, and SeedSigner for signing transactions. SeedSigner would be the only device that ever gets the seed. And it is stateless, so when you unplug it, all memory is wiped including the seed.

> small chance that the same seed can be given to someone else as well? This is called a "collision" and while technically true is so unlikely that our solar system will likely end long before this happens due to how much entropy Bitcoin has so its nothing you should even consider to be worried about. >Also since you can make passphrases or even add custom seed words in electrum how do they work? It creates a completely new wallet that is hidden. More discussed in the pinned FAQ https://old.reddit.com/r/BitcoinBeginners/comments/g42ijd/faq_for_beginners/fouo3kh/ Keep in mind that extended passphrases need to be exact. Whitespace and capitalization matter unlike BIP39 seed words. Thus you should test it https://old.reddit.com/r/BitcoinBeginners/comments/1wjlevd/do_you_actually_test_your_recovery_phrase_or_just/pakeutr/ and be very clear how you right it down (and keep separate than your seed words). Additionally extended passphrases should be 6-8 **random** words as well **this doesn't directly address my concerns with your setup because if the seed words and passphrase are both setup in the same PC than that is a security concern** This is much different than setting you your extended passphrase in a hw wallet itself or elsewhere >From what I understand the seed allows you to control a certain part of the blockchain, no , creates a new wallet with different addresses >custom words are what you make them, no phrases , no sentences . You should ideally use dice to select these 6-8 random words https://www.eff.org/dice >Is the blockchain infinite as well? mathematically not , but so much entropy it may as well be

>it still doesnt have any wifi passwords in it and disconnected the wifi dongle isnt that enough? If you never introduced the wifi passcode to the offline PC (like you downloaded sparrow elsewhere and moved it over with a memory stick) than it depends upon the strength of the wifi password Technically speaking a worm or malware can "crawl" over to your offline PC as you are doing PSBTs if you are not careful and share the wifi password or not even enable networking but just use keylogger software to record the passphrase you type in to share later. There are more attack vectors than just wifi networking and insuring no wifi networking doesn't stop all attacks. Hardware wallets limit the attack surface in many ways and not merely just lacking a wifi card

Even an expert former Bitcoin core dev who used this backup method failed and had most his Bitcoin stolen so simply creating an "air gapped" computer is not enough. I suggest you use a linux live USB to create a new separate seed with multiple addresses for future deposits . Copy the seed down at least twice on paper or metal to store in separate locations. Use this as a cold wallet that you never send money from and keep distinct from the wallet you occasionally transact from. Consider one as your long term savings and the other wallet as your short term "checking account" that you might occasionally use . For your wallet you might send transactions from this might be a hot wallet in ios or android or your offline PC that you can either choose to temporarily use PSBTs or enable networking and not the linux live usb you temporarily used without persistence to create your main savings wallet

For others to read - Its much more ideal to physically remove the wifi card , but at least disable the networking in the OS . Keep in mind that the right malware can potentially re-enable the networking. A hardware wallet physically doesn't have a wifi card typically which is one of many reasons it has a smaller attack surface. >and take it out when I need it and dont I need a pc to do transactions, how else can I do it? That is a contradiction. Taking it out literally means making a transaction which requires direct or indirect network access, thus making your PC no longer "cold" by definition. You can reduce the risk by 1) using a hardware wallet instead 2) Using offline qr code signing (typically used with a hw wallet) 3) Using PSBTs/ Partially Signed Bitcoin Transactions (with or without a HW wallet) Sparrow technically supports PSBTs but this is more complicated and advanced so you need to practice using it and understand that this limits and doesn't necessarily prevent malware or worms compromising your PC so you need to be careful. Hardware wallets simplify all of this. Choosing not to use one creates a lot of concerns and tradeoffs which are fine but you need to understand your choices Is this an issue where you cant afford a hardware wallet or just dont trust any of them ?

>but Im guessing typing it on an airgapped pc is ok? You will have no choice but to enter the seed because you have made the decision to not use a hardware wallet that would normally keep the seed encrypted. With a hardware wallet you would pair it to sparrow or electrum and **not enter the seed**. You have made another decision which has its own set of tradeoffs. 1)Is your offline PC running a security focused OS such as Qubes at least ? 2) Since your offline PC has a much wider attack surface than a hardware wallet have you at least attempted to disable networking in multiple ways like removing the wifi card ? 3) Is the OS a new install or a version of linux live without persistence ? 4) Are you only planning on receiving transactions or also sending transactions out ? If so than why do you need the PC at all after you create the seed and multiple addresses? 5) If you will be sending outbound transactions how will you accomplish this with a offline "cold" airgapped pc? 6) How was the seed originally created ?

When bitcoin was new you could go on a website, click a button and you're get like 50 btc. Thousands of BTC on my mom's PC probably hawked for drugs over a decade ago RIP. Good job on your milestone though!

Bro I mined 300 of those in between WoW raids in school on a piece of shit computer and then threw the PC in the trash because wtf was I going to do with Bitcoin 15 years ago.

Sorry but building a bunch of websites is not the same as AI. AI is about as transformative as the internet or PC itself, or maybe even electricity. The .com bubble happened not because the internet was an issue but because people were trying to build every possible use case of everything as a website. Today, there are like 3-5 real hyperscalers and they are building concentrated services that will power literally everything in the future. Saying there is an AI bubble is the same as the people who were saying we were in a PC bubble in the 70s, not the same as the .com bubble, and you see how the PC bubble turned out.

Yeah, the site's a bit confusing. That big green download button on the homepage is actually Bisq 1. Open the "Downloads" menu at the top and scroll down to the "Bisq2 Downloads" section, that's the one you want. Bisq Easy isn't a separate program, it's the trading mode inside Bisq 2. So install Bisq 2, open it, and Bisq Easy is right there. If you're on Android you can skip the PC entirely. "Bisq Easy Mobile" is on Google Play and it's the same thing. Just don't grab "Bisq Connect", that one needs a Bisq node running somewhere else.

I can see that you previously used [Metamask](https://www.reddit.com/r/defi/comments/1kl5r9h/curvefi_hacked/), and a [service (curve finance)](https://www.reddit.com/r/defi/comments/1kl5r9h/curvefi_hacked/) which has suffered multiple hacks & exploits. Were your Electrum keys generated by, and unique to, Electrum? were they ever shared with any external software? Did you ever install software from curve? and was it on the same PC as Electrum?
