Google didn't give me shit so I'll ask here.

What's the best way (if any) to recover my wallet.dat file that I... um... deleted a few years ago? I've got the passphrases and all that other shit but no wallet.dat. Could Recuva or something be successful?

Also, how much bitcoins you think have been lost over similar reasons? And how much will be? Will there ever be a way to know how much has been lost forever, and will there ever be a way to retrieve that? And wouldn't that actually make crypto less "durable" if coins can be easily lost over user's stupidity?
Just some thoughts. I probably won't be the last idiot to lose their money if the normies are coming.

how about if you found a wallet but can't remember the encryption password? Know roughly how many alphanumeric characters there are but just not the combination. Do I just brute force?

good job faggot you lost your ticket to lambo land. you probably had like 5000 BTC in there.

Let m = the size of the alphabet used to generate your passphrase, and let n = the length of your passphrase. This means there are at most m^n ordered arrangements without repetitions that must be tried before generating your wallet. Given most wallet "seeds" are many words long, including spaces, you might still be bruteforcing after the sun burns out.

m^n ordered arrangements with character reptitions, I meant to say

If you post the wallet.dat file, I could try to crack it for ya.

So we're looking at
upper case 26
lower case 26
numbers 10
total 62

6 characters
62^6 = 56 800 235 584, or about 56 billion combinations

You can build a bot to brute force this for you in about a week on a desktop pc i would think.

If it's on a machine or usb drive with lots of free space and that was barely used in the interim then there's a real chance of recovery

If it's on your daily use pc the chance is much lower

Lost coins increase the value of everybody else's, so there is a positive

You can try with Testdisk and/or Photorec, anon. Good luck!
