GitHub - solar559/Plutus: Bitcoin Brute Forcer

This is going to sound stupid but...

A long while ago, as in approximately a decade ago. I was just killing time and reading articles. Bitcoin was pretty new and was reading about how people were mining with computers. Bitcoin was maybe a few months to a couple years old at the time.
I was reading an article and within the article there was a link to a new coin company that was trying to acquire clients by giving free coin just for setting up an account.
I was like, meh, why not? And did. And that's as far as it went. Divorce happened. Time passed and as far as I know, they're still 'out there' somewhere.
Lately, I've been wanting to try to locate them. I remember a file was saved to my PC. And therein lays my question.
Does anyone know file extensions I should search my old, archived drives for?
It's totally possible it was on one of the drives the failed or on one PC's that was stolen but still, it may be on one of like 15 IDE drives in a box.
Any help would be appreciated.
Edit: If I remember correctly, it was 10 Bitcoin.

Safest Bitcoin Wallets in 2 scenarios: home and travelling - what's your solution?

Hello,
I searched the /Bitcoin Reddit about this topic, but I only found pretty old discussions. I have two scenarios for which I'd like to pick the safest solution:
1) Bitcoin storage wallet at home: at the moment I am using a hardware Trezor that I keep with me all the time (also when traveling), but next time I'll leave home I want to leave it at home. I am not tied to Trezor devices, so what do you think is the safest solution to keep Bitcoin at home? I mean both the wallet and where to keep the recovery seed and/or the private keys. I am not a big fan of cold/paper wallets as they are cumbersome to use when it's time to move the coins, but hey I am open to any solution in the end.
2) Bitcoin wallet when travelling: at the moment, as mentioned in #1, I am travelling with my Trezor all the time but I don't like it, as I know that physical attack on a Trezor it's not that hard in case I lose it. Hence, I prefer to keep the majority of BTC at home while having a small amount with me when traveling. What do you think is the safest (but still usable) solution when traveling?
Any feedback and constructive discussion is welcome!
Thanks.

Bitcoin lost password private key, recovery process after 5 years.

Bitcoin lost password private key, recovery process after 5 years.

These are private keys I created in 2014, than forgot the password.
I was looking for help in web, someone who could crack it and I found Dave.

Ive sent him details and he manage to crack password really quick, in a week, recovering all my money.
Highly recomended service.

Can a quantum computer be used for bitcoin mining?

This has been bothering me for a while.
I'm a newbie in computer science, and I just found out about Grover’s algorithm, which can only be implemented on a quantum computer. Supposedly it can achieve a quadratic speedup over a classical computer, brute-forcing a solution to a n-bit symmetric encryption key in 2^n/2 iterations.
This led me to think that, by utilizing a quantum computer or quantum simulator of about 40-qubits that runs Grover's algorithm, is it possible to mine bitcoins this way? The current difficulty of bitcoin mining is about 15,466,098,935,554 (approximately 2^44), which means that it would take about 2^44*2^32=2^76 SHA256 hashes before a valid block header hash is found.
However, by implementing Grover's algorithm, we would only need to sort through 2^76/2=2^38 hashes to discover a valid block header hash. A 38-qubit quantum computer should be sufficient in this case - which means the 40-qubit quantum computer should be more than enough to handle bitcoin mining.
Therefore - is it possible to use quantum computers to mine bitcoins this way? I'm not too familiar with quantum computers, so please correct me if I missed something.......
NOTE: I am NOT asking whether it is possible to use quantum computers to break the ECDSA secp256k1 algorithm, which would effectively allow anyone to steal bitcoins from wallets. I know that this would require much more than 40 qubits, and is definitely not happening in the near-future.
Rather, I'm asking about bitcoin mining, which is a much easier problem than trying to break ECDSA secp256k1.

Recover Bitcoin Cash from old Ledger

So here's the problem, i got some Bitcoin Cash on a ledger version 1.3.1 which was never updated, updating this version of ledger will reset the device.
I managed to connect it to an older computer and rescued some other coins, but i haven't had any luck with Bitcoin Cash.
I've tried multiple versions of Electron Cash, but 3.1 and later versions says the ledger version is too old and must be updated, while older versions of electron cash can import the ledger wallet, but the network is dead (offline).
So what happened to the recovery phrase you might be asking?
Instead of keeping the whole recovery phrase on paper, i thought it was a good idea to split and encrypt the phrase in different ways on different devices. stupidly, one of those was an iOS app which no longer exists, i only got a screenshot of the icon of this app: https://ibb.co/bHS6tHc
I think it was just called "Encrypt" and i think the developer name looked Vietnamese, but i don't actually have the name or any other details, and i have had no luck finding any trace of this app.
The app was supposed to just encrypt with a password, but i have tried using multiple decryption algorithms, and none of them work. The encrypted string has random looking characters, with three '+'s, then two '/'s and ends with '='
I suspect this may be a PGP encryption that also included a hidden private key which was built into the app.
So i am all ears if anyone has any plausible solution, and i wonder if a hardfork made the old way of signing transactions completely obsolete, or if some software could potentially sign a working transaction using it.
I do have the first 16 words of the 24 word recovery phrase, any idea how and how long it would take to brute force the last 8?

Some direction? (update)

So, from my previous post here: https://www.reddit.com/Bitcoin/comments/ek1vuv/no_clue_where_to_go_from_here/
I now have access to my files, I have access to the password and I know that Multibit classic v 0.5.13 or higher was used.
I see that multibit is no longer supported. I have gained access to my bitstamp account. I am ready to sell.
The problem is that I have no clue how to get from: Point A: A file on my computer. to Point B: Money in my bank account.
I have googled a bunch of stuff related to how to sell a bitcoin from cold storage and all I am reading about is "sweeping" coins and suggestions on apps, wallet hardware, blockchain.info and why its good or bad, and a million other things that just drive me deeper and deeper into being overwhelmed.
I have looked all over my bitstamp account and have not seen any options for anything regarding importing cold wallets. I have read that my cold wallet is actually "nothing" because everything exists on the public blockchain. I have read that the only thing I need is my signature because thats all that matters.
I am lost
I'm feeling pretty stupid asking for help on something that seems so easy to understand, but I could really use some dumbed down direction on what I have to do to get this all accomplished.
All helpful tips are appreciated and the more ELI5 context, the better.
