Whoa, honored to have a BitBox engineer here! I have huge respect for the BitBox02 architecture :P To be 100% transparent regarding the screen and the app trust, you are right about the device in the video. The current prototype doesn't have the screen yet because this project actually started as a P2P LoRa/Cloud Chat application. We were using the SE050 solely for ECDH shared secret generation to handle E2EE messaging, and the payment feature evolved from that architecture. However, for the production version, a dedicated OLED screen and a physical confirmation button are mandatory specs precisely to solve the malicious app vector you described. The flow will be; Phone sends blob > Device displays amount/address on its own oled > User physically confirms Regarding the child seed suggestion, that is a fascinating idea but we ruled it out for a specific reason related to the offline threat model. If the user has a backup or child seed accessible on a PC, it reintroduces the offline double-spend attack. The attack vector would be; attacker pays Receiver offline using the device > attacker rushes home, loads the child seed into a software wallet > attacker sweeps the funds to a new address via a high-fee online transaction > when the Receiver finally finds an internet connection to broadcast the offline TX, it gets rejected. For the Receiver to accept an offline payment with zero confirmations, they need the assurance that the device in front of them is the ONLY signer in existence. The "no backup" policy is what enforces this atomicity. The keys must be physically bound to the silicon's monotonic counters to prevent parallel spending. As for the receiver verifying the hardware, we use cryptographic attestation. During the handshake, the device proves it is a genuine Epheris unit running signed firmware via a challenge-response mechanism using the SE050's certificate chain. Thanks for the sharp questions! It validates that we are tackling the hard problems

A cold wallet is one that is never exposed to an internet connect device. The easiest / most common way to achieve this is with a hardware wallet. A software wallet on your PC / phone, like Blue, is normally considered a "hot" wallet, meaning if your device were compromised by malware etc, an attacker could ship your key off over the internet and take your funds.

Ledger continues to try to find ways to make more money off of its customers, rather than actually improving its wallet software.  - The fact that you *still* can't pair any Ledger device with your PC over Bluetooth is ridiculous. - The Stax is over-engineered and expensive, without a good software experience to justify the price tag. Maybe actually make use of the full screen instead of just directly porting the Ledger Nano UI? - Ending support for the Nano S to try to get people to buy newer wallets from them. - Getting the MetaMask devs to lie to Nano S users, saying that they *need* to buy a new wallet to transfer NFTs.

For ETH your best bet is a 'Safe' multisig. This is what basically every DAO, every dApp treasury, every OG, and even the Ethereum Foundation themselves uses (obviously don't trust me though, do some research to check yourself). A multisig means that you set up a wallet that has multiple other wallets as 'signers' (as many as you want), and transactions can only be sent if a number of the signers, sign the transaction (you set how many you want to require). So as an example, you could set up a '2 of 4' multisig, meaning that there are 4 wallets that can sign transactions for your safe, and you need 2 to confirm before a transaction will go through. The 4 could be: * A Railway wallet on your PC; * A Rabby wallet on your phone; * A Metamask wallet on your spouse's phone; * A key that only exists on paper at your parent's house. Normally at home you just use your PC and phone, if you are out you can use your phone and get your spouse to confirm on theirs, if your phone breaks you can use your PC and your spouse can confirm, if you and your spouse both lose your phones while kiteboarding the you can retrieve the spare key from your parents... And if someone hacks your PC they can't get your crypto, or if they steal your phone, or rob your parents etc... Obviously as you can have any number of devices as signers and any number of required signers to confirm then you can make the setup as complex and secure as you like. Anyway, here's the link: https://safe.global/

Ha I did that a while ago to see what my 3080 is actually doing. It was something like 127 years to search .01%. I have mine running on random mode while it is cold outside. Hell I have my work PC running the 3050 24/7 at 600m/keys sec. [https://btcpuzzle.info/](https://btcpuzzle.info/) breaks it down into chunks and methodically keeps track of searched keys but still lets the lucky user keep the private key to themselves if found. Just helps us not search spaces already covered. Its for sure a lottery. Entry fee is a graphics card and electricity.

Can you buy groceries with hashrate? A coin from satoshi era is mined with the hashrate of his PC, does it make the coin any less valuable? Price decide the hashrate, not the other way around. People really don't eead the white paper nowadays.

Massakahorscht

Maybe check the spector diy. It is a hatdwarewallet which you build by youself. Buying all the parts seperate on normal Websites etc and creating the seed by poor luck by you and some gaming cubes and coins etc. Check it out, it is really cool and you create it for example with other software wallets like spartow etc. Also there are some offline laptop or PC variants in General. But i would say try the spector diy( maybe there is already a neuer Version, i dont know right now )

Blade_Runner_69

Moving from proof of work to proof of stake has been a complete disaster for Ethereum, and all the talking points of "saving the environment" was total nonsense because AI data centres have been way worse. Also AI has destroyed the PC buying and building market for the everyday PC enthusiast.

Zippo156

I have a question: Is there a way that other miners know the positions you tried and adjust their strategies accordingly? Or why do you receive small rewards even if you don't have enough mining power (e.g., on a small PC) to reach the target?

Inventor-BlueChip710

Check GrahamBell, it caps PoW mining attempts to 1 hash/sec/node at the protocol level making 1 Phone = 1 PC = 1 ASIC. No Mining Pools, Capital Advantage, Hardware Dominance, or Parallel Mining. You can learn more here: https://grahambell.io

Honestly, I’m not real versed in PC stuff. So I am going to assume so. I don’t care how long it takes, I’m just trying to to get it past this screen

MrBluoe

There's a reason Bitcoin is king. Only get Bitcoin. If you have time to spend +12 hours a day on the PC, then maybe some other coins, but they can still crash when you're sleeping, so personally I stay away. I like sleeping without fears.

riscten

It's more nuanced than that. If you run a fresh OS on a PC with radios (Wifi/BT) disabled or removed, you've essentially created a hardware wallet. A hardware wallet does not fundamentally need a secure chip. In fact using any wallet in stateless mode (not storing the mnemonics on the device at all) is safer than storing on any secure chip. The primary purpose of a hardware wallet isn't to store mnemonics, it is to generate keys and sign transactions. Mnemonics are ideally stored on metal plates. Finally you can generate BIP32 hierarchical deterministic wallets on PCs just as well, allowing you to have an infinity of addresses and preventing address reuse. You can use Sparrow for this.

riscten

An airgapped PC with a clean OS is a perfectly valid hardware wallet, just make sure that it's actually air gapped and backup your mnemonic on metal.

FromThePits

I really appriciate your dedication. Also the estimate on CPU runtime. Thank you. I promised some other redditor to release the xpub early next week, if that is useful to you? He wanted to verify the 0.01 BTC incentive is real. I promise its still there. I just checked. Other than that - the challenge is the challenge. You'll probably waste more electricity than its worth with that PC? Maybe you can team up with someone? Get some more hashing going.

Deacon86

This shit is why we can't afford new PC parts.

omg_its_dan

Hardware wallets had a secure chip that ensures the seed phrase does not leave the internal storage. There is no such firewall on a random PC. With this approach you’d also be consistently reusing the same deposit address which is not ideal from a privacy standpoint. This is just not something to cheap out on if you have any real amount of bitcoin. A solid HW wallet can be bought for less than $100.

Trust wallet is not an open-source wallet. The most recommended wallets by this community are BlueWallet and Blockstream BTC Wallet. The are open-source and heavily audited. At the very least, get BlueWallet (on iOS/Android), make a new wallet, and send your BTC there. For about 0.1 BTC - as you say you have - you should *seriously* consider getting a [hardware wallet](https://trezor.io/). You could also set up an air-gapped Linux PC for wallet generation, but that's more work and easier to fuck up.

Speculation time : I still think that if there's another alt season it will be related to AI. There's been a lot of improvement on small models but also on decentralized training and inference lately. Large LLMs are still ahead but they cost a lot in development and infrastructure. We'll soon reach a state where it won't be relevant to pay for state of the art large models for casual usage. It will also be less convenient than runnning a small efficient model locally on your phone or PC. We'll also see the emergence of autonomous economies running across the net. Agents who will pay for processing power, coding improvements, data scrapping, training, trading, posting on social medias and so on. These economies won't run on tradfi infra. Imagine you'd have to open a bank account for every bot out there to fully deploy their potential. It's much more convenient to just allow them a capital in crypto. And let them invest it.

flying-fox200

Hmmm... I'd generally recommend *against* Exodus due to it not being open-source. One of the most recommended wallets on here is BlueWallet (for iOS/Android), or Blockstream BTC Wallet. Also, it's best to use a hot wallet on iPhone/Android rather than a PC, as mobile operating systems are *much* less prone to malware than a PC.

Lost_Box_5926

That was proven to be false, as you said said they never had over half of the network's hash, of course it is still a threat but literally the more people that know about Monero and contribute to the network's hash the less one singular pool can be a threat. If this were a thing with BTC it would be a problem since the entry level to BTC mining is thousands of dollars for some good ASICS. In comparison to Monero, which is ASIC-resistant and anyone with a PC can actually contribute to the network making decentralization much more realistic.

Deacon86

This shit is why we can't afford new PC parts.

crunchyeyeball

Do you mean using the exchange itself as a wallet? If so, that's a very bad idea. The question you need to ask when deciding how to store your bitcoin is what happens if company X goes bust, or I lose my PC/phone, or I wake up to find my account has been "frozen" for some vague reason? Not Your Keys, Not Your Coins. Apparently they do actually offer a self-custody [wallet app](https://crypto.com/uk/onchain), but it seems to be closed source so I'm skeptical, and I prefer a hardware wallet anyway.

Equivalent-Tip-3084

ETF skims your BTC in fees, and usually is letting someone else hold the Bitcoin. Learn to use a cold wallet. Trezor is extremely easy if you have a PC. Just remember to never click on anything from an email, even if it looks like Trezor sent you an email. In fact you should never give Trezor you email either. 

Amber_Sam

>brand new pc not even one application installed I'm guessing you didn't install the OS. Even if it's brand new PC, it doesn't mean someone else didn't install any apps. The wallet isn't hacked, your PC is compromised. This is why having a hardware wallet is important. If you'll be looking for one, make sure it is **fully open source** (not ledger), **Bitcoin only** - the attack surface reduced to a minimum (not ledger), and **air-gapped** (not ledger). Blockstream JadePlus for example but there's more options. If you still don't want or can't to buy one, look at DIY solutions like Seedsigner, Jade or Krux. If that's a no go, at least download a live linux distro and use that instead of using (I guess a windows) OS, somebody else installed.

crunchyeyeball

Sounds like either malware or a fake wallet. Have you added any browser extensions? Where did you download sparrow from? Does anyone else have physical access to the PC? You say the PC was brand new - where did you get it? Are you sure there were no other applications installed? If you can't figure out how it happened, I'd be tempted to just get a hardware wallet, maybe a Trezor or similar. Even then, I'd be wary of any malware on that PC until a full OS re-install.

Own_Condition_4686

You’re gonna have to reinstall your operating system or buy a whole new computer. Do not try to use sparrow on that PC again. Personally I wouldn’t even use a computer that was connected to the same home network. If you’re storing any meaningful amount of BTC use a cold wallet like Trezor. If you need to spend or transfer then you can transfer to a lightning wallet on your phone.

flying-fox200

This. Mobile wallets on up-to-date iOS/Android devices really are quite safe (as long as you don't do something blatantly stupid). Obviously, an air-gapped device (hardware wallet or air-gapped Linux PC) should still be used for significant sums, but BlueWallet on iOS/Android is perfectly reasonable for maybe ~0.01 BTC.

riscten

Storing on an exchange is far worse than on a phone/tablet. Bitcoin sitting on a exchange can be taken away from you for so many reasons. Platform gets hacked, operators decide to run with your money, company goes down, authorities issue a seizure order on your account... Storing on a phone is very different from storing on a desktop PC. Mobile apps are sandboxed and accessing app-specific data is much harder to do for a malicious app than it is on a desktop OS. It's an order of magnitude safer to keep your Bitcoin there, with the exception being obviously rooted ROMs and random APKs you installed from who-knows-where. Obviously an airgapped wallet is a much better solution, but between exchange and mobile, I'd pick mobile every time.

MoistService2607

You never want to type anything into a PC or other type of general purpose compute device for a “Cold Wallet”. That generally means they’ll have displays. Displays do go bad. I had a Trezor display get so faint I could not read it. That’s why you have a backup seed etched into metal somewhere. Another alternative is to create your own public and private keys by hand. Send your bitcoin to your public key. You don’t even need a wallet.

anon0937

I use my PC to mine crypto instead of a space heater during the winter. Works like a charm

Dexx1976

I thought that. But malware on my PC gave a hacker access to Binance via a left-open web page. Even though i have google MFA on my account, they still managed to withdraw. I dont know how.

Billkr

There is no way to mine Bitcoin from your phone. PC CPU and GPU mining died years ago. If you want to mine bitcoin, purchase a Bitaxe miner and lottery mine.

Money_Storm8799

On the Trezor. Never enter a seedphrase into a general purpose device like a PC or phone.

Mighty_Buddha

There's quite a few, actually. They either have you run an app (PC/phone) or an extension in your browser.

LeSplooch

That's exactly why I do everything crypto on my phone rather than on my PC, there are more security checks and features on a phone with Android or iOS that will prevent such issues and hacks, and Windows is generally more of a target for hackers. It doesn't make a phone invulnerable to hacks for as much, but it's still more secure than a Windows PC and it's at least not as easy to mess with the clipboard and other things. Use your phone instead of your PC whenever you can.

disruptioncoin

You really gotta check at least the last 6 or so characters of a receiving address before sending anything. And re-install windows. I wouldn't even create the iso/download it on this PC tbh, borrow a laptop or something.

riscten

100% Jade. The way they implement stateless mode and airgap is excellent. It's one of the few wallets that gets it right, enabling it to be an absolute fortress for your wallet. The great thing about Jade is also that you can build your own relatively easily, just like Seedsigner, but their codebase is a lot simpler, as it is meant to run on the ESP32, a microcontroller, instead of a full blown Linux computer like Seedsigner uses. This makes the system extremely verifiable and much easier to audit. Trezor is good, but doesn't support airgapped communication or even PSBT over an sd card. It relies on USB or Bluetooth (Safe 7 only) to communicate with your phone or PC, which greatly increases its attack surface.

They can technically mine sha-256 (btc's algorithm. Here are some stats ai spot out. Reguarless is they are 100% correct... The odds are astronomical. You are MUCH better off playing the lottery "Attempting to solo mine a Bitcoin block with a standard PC CPU is virtually impossible for earning Bitcoin today. It's not about luck but about the extreme difference in computing power between your computer and professional mining setups. To show you why, let's compare the hash rates: · 🔬 Your PC's CPU · Hash Rate Example: 0.0001 GH/s (100 MH/s) · Representative Hardware: Consumer CPU (e.g., Intel Core i7) · 🏭 Entry-Level ASIC Miner (considered minimal for solo mining) · Hash Rate Example: 6 TH/s (6,000 GH/s) · Representative Hardware: Older-generation ASIC (e.g., Antminer S9) · ⚡ Modern ASIC Miner (competitive hardware) · Hash Rate Example: 140 TH/s (140,000 GH/s) · Representative Hardware: Bitmain Antminer S19 XP · 🌐 Total Bitcoin Network · Hash Rate Example: ~500,000,000 TH/s (500 EH/s) · Note: This is the combined power your PC competes against. 🤔 Understanding the Odds and Challenges The chance of finding a block is your hash rate divided by the network's total hash rate. · With a PC CPU: Your probability in any given 10-minute window is astronomically small—effectively zero. It would take billions of years on average. · Even with a single ASIC: A miner with 270 TH/s had a 1-in-30,000 chance per day (roughly once every 82 years on average). · Recent "Luck" Stories: In late 2025, a miner with just 6 TH/s beat 1-in-180-million daily odds to win a block. Another with 270 TH/s had a 1-in-30,000 daily chance. These are considered extreme lottery-level wins.

Just be sure to check back in on it when you do this. I cheaped out on a few when moving my wife's coins to her wallet before leaving for a while. 18 months later, I turned my computer back on, let core sync, and opened Trezor suite. The next day I saw a recent and mysterious $10k transaction from my Trezor. At first I panicked thinking I got hacked somehow, which should be quite difficult to do unless my seed got compromised. But rationality reigned me in: who only steals part of a wallet? And then I realized it was from a labelled address I had previously kept my wife's funds on. Turned out my transaction had never been confirmed to a block 18 months ago, but finally did when I turned my PC back on. Best I can surmise about what happened is: when turned my PC off before I left, the transaction was still in my Bitcoin nodes mempool. When it came back on 18 months later and re-synched, the transaction was re-broadcast, as Core does. Which makes sense because it's very unlikely any other node would hold a pending transaction 18 months. So yea, just check in on low fee transactions to make sure they complete.

oak1337

No. Again, permissioned vs permissionless does not effect Hedera's Fair Ordering. Hedera’s fair ordering is a result of the Hashgraph algorithm, not the council or node operators. The use of a Median Timestamp (consensus on when a transaction was received by the network) mathematically removes the ability for a single "leader" to decide the order, regardless of whether the node is a Google-run server or a home PC. You're saying Algorand’s "First Come, First Served" (FCFS) is "good enough" because the proposer is chosen randomly and secretly. I'm pointing out that "good enough" is still a vulnerability that allows for financial exploitation, which violates the core purpose of a DLT. On Hedera it's mathematically and architecturally impossible (nothing to do with permissioned/permissionless). On Algorand it's harder, but it still exists, and it will be exploited because it exists.

Zestyclose_Narwhal43

Genuine question, sorry if it’s dumb but do I need a PC to transfer my coin to a cold wallet, if so how do I protect myself from any kind of leak or exposure. I want my coins safe but I am completely computer illiterate

PapayaJuiceBox

Better than the guy whose PC ended up in a landfill.

brtastic

1. I was buying 0.1 btc for $350 multiple times, only to convert it all to shitcoins right away. 2. I once used a javascript application working as a web page to get some info about my seed phrase. Did it correctly: downloaded from github, ran offline, closed before going offline. The problem was that a year later, my browser randomly restored that page for me, together with my seed phrase as form input field. So I was effectively running a hot wallet for a year, on a windows PC, which I don't trust to be very secure either.

bandures

Probably it's someone like my bro. His co-workers presented him a bitcoin mining PC for birthday around 10 years ago and he plugged it in and forgot about it. He mentioned it a couple of years ago as we discussed crypto and he said he never checked into it and he probably hasn't checked since.

Nomad_Soul1988

I think this tool will help you: https://github.com/BitGo/wallet-recovery-wizard/releases?page=13 but it's best to use it offline on an old PC without internet. If you have any questions, feel free to write to me :) I'm not a stupid scammer who wants your data. The format iv... what you have is probably an encrypted seed phrase but you need to know the correct password to decrypt it. 

HedgehogGlad9505

Does the wallet have 12 or 24 English words, maybe also an extra passphrase? If so, get a clean phone, e.g. an old one and factory reset it. Then go to https://bluewallet.io/ and choose the link that should direct you to the official app store. Use "import wallet" and enter the words in exact order. You should be able to see how much in it. Then turn the phone off and decide what to do next. If you already know it has more than 1k dollar, skip the blue wallet part and buy a Trezor hardware wallet. Then follow the manual. Electrum is also good, but it's on PC, and most people don't know if their PC contains virus. Also NEVER enter these words in any web browser, your money will be gone in 10 minutes max. Don't answer to DMs. If you are not sure how to proceed, ask in public and only respond to public comments.

Docc653

I was a big advocate for BTC back around 2017 with all the hype, first fomo etc I was gifting friends with 50 bucks worth around 3000 usd btc Guess what? No one bothered to keep the keys safe (I deleted them from my personal PC cus I thought was being a good friend) lol

flekinjos

Even putting aside all the Ledger’s user info leaks (which you can circumvent by buying a cold wallet from a reputable brick and mortar vendor), Ledger sucks in my opinion because it forces me to always update the wallet’s firmware and PC/phone companion app, just to do a basic transaction. Now, I wouldn’t want to have to update every time, because I don’t have the time nor will to track all the bullshit they add into their software over time (shitcoin support, ads, and most of all - ability to send them your passphrase for “safekeeping” lol). Either go for different company (as many have suggested - Trezor), or use an old phone (restore it and never connect it to the internet/wifi again) as a cold wallet with air-gapped wallet combo (there are several app pairs, such as AirGap, that allow for this).

Fuzzy-Membership4026

I have almost 15,000 USDT in a wallet that I saved its 12-words in Lastpass. The stupid me memorized lastpass master-password by memorizing the location and order of the keys on the keyboard on my MacBook and not the accual password. When I switched to Ubuntu on PC, the same keys order on the keyboard didn't work ! The different keyboard layout between win-mac keyboards missed up my mind and I couldn't find the correct combination. It's been almost 2 years now and I can't solve this keyboard layout difference.

Aussiehash

Learn how to use a reputable open source hardware wallet, and make sure your mnemonic seed phrases never, ever exists in digital form outside of your hardware wallet. You must NEVER enter your mnemonic seed into your phone, PC, browser, password manager, cloud or photo album

crunchyeyeball

Memorizing it is fine, but ***only*** memorizing it is crazy. You'll likely have forgotten it by the next market cycle peak. At 20 years old, you've likely never tried recalling stuff you memorized 5 or 10 years ago. Hell, whenever I come back from a short holiday I've usually forgotten the password for the office PC I use multiple times per day. If you can't trust those around you, then at least scribble clues in some random book nobody else will read.

Sorry to hear that. That’s one of the reasons why we build PlugOS to secure assets and data without trusting your mobile or PC.

I lost a few bitcoin but didn't even have an actual wallet yet. This was probably sometime around 2011 if I had to guess. the best I can trace it back was I remember hearing the news that bitcoin hit $100 for the first time and that reminded me of when signed up to mine it. I searched back through my email and found the site I signed up for. It placed miners in groups and divided up mined coins between them, and your account held how much bitcoin you had earned until you manually transferred it to a wallet. I tried logging in and no such luck. I checked the site and found they had a disclaimer that accounts that were dormant for over a year had any coins redistributed. I checked and it was well over the year mark. The best I recall I had somewhere in the single digits, more than 1 but not more than 10. I don't recall more accurately because at the time it was a novelty that I had built a new PC after college and didn't need to have the portability of a laptop any more, so I had fun with the stuff like bitcoin mining or folding@home and such. with the new processing power. I never imagined bitcoin would be anything more than a novelty. when it hit 50k or 100k i felt a little bad for missing the boat, but had I saved those coins, I would have sold them at $100 or at least at $1000. no way I would have held onto them until 100k. I might as well be sad that I didn't buy the right lottery ticket any time any powerball numbers are drawn.

"Not your keys, not your crypto." Comes to mind here... OP, if you're worried about security, pickup a hardware wallet. Trezor, Ledger, etc. store backup keys offline (never touching, typed, shown, etc.) to an Internet connected PC. Then security of a given exchange doesn't matter too much as they simply become the ramp.

THIS IS AN ESTIMATED AMOUNT — NOT EXACT! I wrote it off my PC so you can see where i am at...

As long as BTC isn't as simple as having a bank account, ETFs are for the masses. Your dessilusional and living in the BTC bubble when you expect that anyone is able to handle crypto today. There are people not able to handle a freaking PC. And don't even start with Smartphones. So break down your expectations and face reality: ETF are the best thing happened to BTC and crypto in a long while, as it creates the path for mass adoption and enables people without a clue about crypto to invest in it. Your "not your keys bot your coins" argument isn't valid here.

> This whole digital Euro thing is just a study the EU is commissioning, there is no guarantee that anything will come out of it. Honestly, I don't think this is true. They have already published the proposed legislation underpinning the Digital Euro. They intend these to be passed in 2026. https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:52023PC0369 And https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:52023PC0368

Also you can use a dedicated offline device for encryption that way your keys are never exposed For example an old PC with no WiFi or Bluetooth chips running fedora with full disk encryption used to encrypt the files before moving them to an online PC using QR codes or one time use SD card/USB sticks that are destroyed after The only problem i see is that if I know your using this I could kidnap you and wait 30 days for the money Nice write up thanks

For PC wallets, something like Exodus or Atomic Wallet is usually less noisy and pretty beginner friendly. I use IronWallet on mobile and keep my desktop setup boring on purpose.

__redruM

Can you make an account on Kraken and transfer them? Or even just setup a wallet on your PC or phone?

noviwu97

I mean if you connect Hardware wallet to a browser extension, the keys are still offline within the hardware. So if your PC got hijacked by remote control virus or there's key stealing malware like in Trust Wallet's case, they can't steal anything from your hardware wallet. Also hardware wallet doesn't mean cold wallet. Most serious people are transacting in DeFi with hardware wallet.

UrbanBoyToronto

Hey all, I appreciate the feedback, but let me add some context because the thread blew up way more than expected. My kid definitely isn’t missing out on being a kid. This wasn’t his only gift; he got other presents too. On top of that, he already has a pretty big Pokémon collection, including a few PSA 10s he’s proud of. As for the Bitcoin part, he’s actually been doing this for a few years now. It’s not me forcing anything on him; he uses his allowance, birthday money, and whatever he saves. A few months ago, he even used some of his profits to buy himself an e-scooter. So he understands the idea of saving, spending, and earning. And trust me, he’s not short on toys. He’s got a PS5, VR, a gaming PC, and a Roblox account with more in-game purchases than I’d like to admit. So, yeah, he still gets to be a kid. Also, his sibling has their own wallet too. I’m just trying to teach them both about money early, in a way that’s fun and age-appropriate.

AmishCryptoGuy

So you had your private keys on your work PC? You cant just "brute force" encryption

GrumpyOldBtard

Well the only proof is that I used a work PC for transfer and home PC. If he denies it, then what can I do?

GrumpyOldBtard

Yeah I know but it was early days of Bitcoin, i made a terrible mistake of using a work PC and even though the file was password protected and deleted they still eventually got into it.

GrumpyOldBtard

Why? Because greed and people are shit? It was my former boss. They recovered an old file from a PC and brute forced it most likely

Cold Wallet and Hardware wallet are not the same. You can create a cold wallet with a pc and no cost at all. You just make sure the PC is offline and create the wallet, then make offline (physical) notes of your public address and private key and remove everything from the pc. Then you deposit to the public address and that is a cold wallet for as long as you don’t need to transfer out of it.

Squeiner

Bitcoin is a computer program that you (or anyone) can run on your PC. What the program does is to implement a monetary system which networks with other people who are also running it on their PC, creating a monetary network. What's interesting about it is the characteristics of the monetary system it implements. It's inherently borderless and global. It does not rely on a central authority to track spending or supply new tokens. It's permissionless. The native token is supply capped at 21M units, each divisible into 100M smaller pieces called Satoshi or Sat (Plural Sats) named after the Creator of the program Satoshi Nakamoto. There's obviously much more to it, but essentially proponents tend to think that this will be the money of the world in the future, and detractors think its collapse is imminent.

Haha... no worries! Air-gapped means the laptop/PC is **not** connected to the internet and - usually - is **incapable** of connecting to the internet. The most extreme way of achieving this is literally by ripping our your Wi-Fi card... (I don't recommend 🤣). The way I did it - which I guess is second best - was by unloading and blacklisting all the networking modules at the kernel level. This is already a pretty high level of paranoia... simply booting into a live Tails session (from a USB) and not connecting to any network would likely be sufficient.

mrjohntalbain

Awesome, thanks for assuming I'm on a PC (I am). Total n00b here, what does air-gapped mean?

flying-fox200

Yeah, all you need to generate wallets is the right software...! Remember that wallet programs are just clever pieces of code. The main selling point of a hardware wallet is that the keys are generated **offline**. However, as batty_spark mentioned, you can just run the exact same programs on an air-gapped Linux PC and achieve the same results. I wrote my own Python programs for generating wallets, but there are plenty of reputable open-source wallets that you can copy (securely) onto an air-gapped PC and generate wallets. I'd recommend Sparrow Wallet.

SteveW928

You can buy ASICs. I doubt the OP was going to try mining with their PC. Running a node is great, but won't do anything to help decentralize mining. I think maybe you're the one who is confused.

dividedSt8s

Buy it. The electricity cost is only part of the equation. Equipment is also a factor. You can’t mine BTC reliably without specialized hardware that is power hungry, loud, and put off a lot of heat. Your home PC isn’t going to do the trick even if your electricity is free.

MatteAce

but is it constrained by physics? it’s the protocol that defines the difficulty of the proof. ASIC miners has taken advantage of this to cut everybody else’s off from mining. If there was no ASIC technology, or if the coin was code-constrained to be CPU-bound, we’d still be mining with our home PC probably.

Consistent-Square742

I mined some back in 2013. BtC was 200 at the time and I only had like a tenth of one cashed it out later for like 6k. It happens more than you think, especially if its on some PC back in the day.

ThatsNotRich

Ahhh that black wd80 brings back memories man! Had it on my original PC and it didn't let me down. 

CortaCircuit

Sell the PC, trade on the library computer. 

claykiller2010

Can I make my one "one shot miner" with a Raspberry Pi? That actually sounds like a fun project to get me back into a Hobby that isn't PC gaming, golf or going out and spending money at the bars haha.

think it is very important just to learn how Bitcoin seeds and wallets work. Just go to Iancoleman.io/bip39/ and play around with it. Generate a 12 or 24 word seed and look at the addresses that are derived. Then add a passphrase and look how the addresses have changed.  Put the seed + passphrase into a "legacy" sparrow wallet on your PC and see how the addresses it generates are the same as the derived addresses on the ian coleman website. Then repeat the process when an entirely different wallet on your PC. Blue, or electrum, etc. See how the addresses they generate are the same as the derived addresses on the ian coleman website. Then grab the "account extended public key" from the website and stick it into a sparrow wallet "watch-only" wallet on your PC and see how the addresses it generates are the same as the derived addresses on the website. Repeat the process with other wallets. These little exercises will get you comfortable with seeds and passphrases and drive into you that Bitcoin and the blockchain are independent of the hardware or software that you are using. I wish someone had told me this stuff when I first started out. P.S. MAKE SURE TO NEVER USE ANY OF THESE SEEDS IRL. To use this website to generate your actual seed involves an offline process that you can learn about later.

Lanky-Occasion8005

To enter the passphrase in the Trezor One you have to type it in your PC's keyboard.

longonbtc

BlueWallet, Blockstream BTC Wallet (Green), and Nunchick are good open source wallets for your mobile phone. Sparrow and Electrum are good open source wallets for your PC.

ShittingOutPosts

If you use a hardware wallet and never input your seed phrase anywhere on your PC, do you still have to worry about kernel level anti-cheats?

RetiredAvocado

Trust must be placed somewhere. Do you trust the keyboard you're typing on? Why, because it doesn't appear to have keylogged and stolen all your passwords yet? Did you examine all USB or wireless signals the keyboard is sending to PC? Do you trust TailsOS? Why, because you audited all of the source code and compiled it yourself?

seanmg

Did mom pay your electric bill or are you just ignoring those costs?   Did you have dedicated mining rigs to make any meaningful amount of money or were you using your consumer PC to mine pennies worth of XMR?

SmugPolyamorist

Not true. The earliest versions of the bitcoin client had CPU mining functionality included, and it was still worthwhile for most of 2010. Early 2010, difficulty was 1, and it was still under 20 until the summer. 1MH/s, performance achievable from eg. a Athlon 3800 X2, already out of date by that point, would be good enough for nearly a block (50BTC) an hour in January, and about a block a day by June. If you could buy a PC like that, or just use a public one, or get an office job and use one at work, you could easily amass a fortune - about 100,000 BTC by the end of summer. 100k BTC is enough that you wouldn't have to wait long to be rich. The price spiked up over $20 in mid 2011, sell 10k at that price and you're comfortably off until late 2013 when it went up to $1k, and you'd have about $100m.

If anything I'm trying to get AWAY from this noise, so I like the alerts, but I would much prefer this to be a website rather than an app and the alerts to be email-based, so that I don't have yet another app on my phone AND I can actually use this from a desktop PC or laptop, not just a phone/tablet. I think you'll find people on this sub to be largely uninterested in this app as 1. Most of us are really only interested in Bitcoin, not any of the shitcoins, and 2. Most of us are not traders; We hodl and care very little about the price swings.

I don't talk about my stash, but, I'll just say that 2010 was a good year for my PC. It earned its keep.

Hedera's architecture offers several unique ways to mitigate these challenges, leveraging its high speed and ABFT finality. This is why synchronous or partially synchronous chains (basically everyone except Hedera) will have difficulty solving this problem, and why Asynchronous is a requirement. Hedera's sharding roadmap (Hybrid Sharding) leverages its unique L1 properties to tackle these problems more effectively than probabilistic or slower BFT chains. Hedera introduced Atomic Batch Transactions (HIP-551). Developers can bundle multiple operations (e.g., transferring HBAR, minting a token, and calling a smart contract) into a single batch that is submitted to the single, global Hedera L1. The ABFT consensus ensures this batch transaction is executed with ACID properties (Atomicity, Consistency, Isolation, Durability). It either succeeds completely or fails completely. This solves the composability problem within the L1. Because ABFT provides finality in under 3 seconds, any cross-shard protocol (even a 2PC or 3PC) has a much shorter locking window than on chains with probabilistic finality (which can take minutes or longer). The rapid finality minimizes the time the state is locked, greatly improving throughput. Hedera's sharding model proposes a Global Coordinator/Committee layer responsible for managing cross-shard transactions. Since the underlying consensus is ABFT, this coordinator layer can be trusted implicitly, minimizing the need for complex, bandwidth-heavy Merkle proofs or repeated consensus cycles across every involved shard. The ABFT ensures the Global Coordinator's view of the state is quickly and definitively known.

so as a vietnamese living in aus i went aboard to study when i was exactly 18 now im 21. For the first year and a half my parent was worry sick and send a bunch of money like 8k AUD per month. Being so young at that time i know if i keep it in my bank account i ll just spend all of it. And luckily btc was so low at that point like 17-25 i dont really remember, so i just put all the money i have in there ( well to be fair i probably gonna have 2 3 btc if i didnt burn all of it in PC laptop, games, and bunch of stupid shit) but still thats my story but i think im the lucky one

In the end, among all these L1s, it seems absurd but only Pi Network seems to have embarked on a machine-to-machine payment path and a node can be a laptop, it doesn't need power but scalability and a high number of cores/threads. When it will be used with OpenMind you'll be able to decide how much CPU to use for the required computing power and you get paid in PI, micro payments will be made in USDC, there's already the Circle-OpenMind agreement. I thought it was a sort of useless crypto but if someone has been following in recent months, now more than 400,000 PCs are connected in testnet, when they move to mainnet it will be one of the largest decentralized networks in the world. I tried it too and obviously I don't have high economic returns but I also don't have high hardware/electricity bill expenses because PC is idle and I can work in the meantime.

He could barely move anymore, let alone throw his PC's on the dump. You are saying he disliked his wife and kids so much he deleted the coins on purpose?

bigbiblefire

First time I ever bought BTC it was off ebay. Needed .05 to pay to unlock an app to make custom crew emblems for GTA Online....when it FIRST came out. Had to buy .1 on ebay because it was the easiest/cheapest way to send .05. Had a simple wallet on my PC to receive/send with. Used it once and never again.

You could just mine it on your PC, then buy weed with it on Silk Road.
