Can old Bitcoin from 2010 be recovered?

Hey everyone, I’m pretty new to crypto stuff. My friend thinks he bought some Bitcoin back in 2010 and kinda forgot about it. With how Bitcoin is worth now, it must be a big deal, right? Reason he didn’t check earlier is he didn’t think it was important back then.

Not to sound harsh, but a 16 character string doesn't mean much. Can't be an address and definitely not a private key. Maybe it’s a brain wallet? But that’s a long shot. If you think it’s worth it, get a pro to recover the disk.

Totally agree! 16 characters? That’s too short for anything Bitcoin-related. BTC addresses are usually longer. You’ve got the hard drive, though, so check for private keys. Use that address prefix list for reference to see what a real key looks like.

Just throwing this out there but Mt Gox confirmation codes were 16 characters. If they were using something like hotmail, check old emails for that string. If you find it, you might access your account. But if it’s Mt Gox, sorry, but you probably missed your chance.

Seriously, look for any physical backups first. Like, written private keys or something. Given the age of this crypto, it's not USB or seed phrases you should be searching for. By the way, that 'key.txt' doesn’t seem like a proper private key anyway.

Right? Old exchanges from 2010 may not even be around anymore. If he used any in late 2011, ask him if he remembers Kraken or Bitstamp. Those might be important. And remember, a Bitcoin private key has to be 256 bits. Can’t squeeze that into just 16 characters.

I got two questions did he use a web wallet or any exchange back then that might still work? I wanna check if any of his old emails could help us out. Also, if we dig out more old drives, what should we look for? Anyone know specific keywords to search for?

For the love of Bitcoin, reach out to a pro data recovery service! Trying to do it yourself on a broken disk is risky. And honestly, I think he probably used Mt Gox. Bitcoin Core wallets are complicated, he might not have gone that route. Also, blockchain.info came later, so that’s probably not it.
