How long would it take to brute force the rest of the private key?

Unfortunately, recovering the full private key with just the first 9 symbols is highly unlikely. Since the amount is not negligible, It would be a good idea to look for a paper and document restoration or forensic laboratory in your local area that specializes in handling situations like this. They might have the expertise and tools to assist with reading the other characters from the damaged paper. Reading other characters from paper might be easier than attempting to brute force the missing characters of the private key. Good luck!

Take a picture from only the half of the paper and post it here, no one can help you based on speculations, we need to see what you are up against.

I said we, not that I am an expert or anything, figure speech.

The issue is, I don't know any private key bruteforcing tool that does that so you might have to search for one yourself of find someone to code it for you.

The feature to limit search space when recovering Base58 inputs was added to FinderOuter in version 0.15.0.

Well in the meantime we should understand if the seed is 12 or 24.

OP is talking about a private key and that's different from a seed phrase.
Th most common format of a private key is WIF and that includes 51 or 52 characters. Even if the private key OP is trying to find is a mini-private key, it would include 22 or 30 characters and as mentioned by mocacinno and LoyceV, that can't be brute-forced.

oh fuck...i didn't read private key and my mind automatically deduced that it was a pass phrase...you're damn right. So here things change a bit and only prayer remains as an option.

The thing is that it is old-washed paper and I can read only the first 9 symbols of this string.

But since it's not torn, the rest are still barely visible, yes?

If so, you may be able to lower the characters to bruteforce by guessing the possible washed-out characters.
Depending on the condition, you may be able to minimize it to a doable difficulty.

For example: a small circular washed-out character could be an 'a', 'o' or 'c'.
Then when bruteforcing the private key, input those as the possible characters of that specific place.
The issue is, I don't know any private key bruteforcing tool that does that so you might have to search for one yourself of find someone to code it for you.

If it's totally unrecognizable, then there's no chance to bruteforce it.

OP, anyone sending you a personal message to help you find your private key or asking you to send/him a personal message is a scammer.

Well in the meantime we should understand if the seed is 12 or 24. If it were 12 it could take a long time but maybe with a bit of luck it would be plausible if it were 24... well if it were 24 you could try praying. However, if the other characters were present but not readable, perhaps with some tests such as those of TV series such as CSI it would be possible to recover the sentence. Try posting a picture of just one damaged font, so maybe we can gauge how bad it is. Only one character not the whole sheet.

But, truth be told, unless it's in mini private key format, your odds are allmost 0 when you can only read 9 characters... (and even if it's in mini private key format, it'll probably take more time and effort than it's worth... I didn't do the math, but my gut tells me that even in this case, it's allmost impossible)

Even if it's a mini-private-key, it's impossible to brute-force from 9 characters.

You'll need to find a way to read the other characters. Try bright light, adjust the contrast on pictures, or get a microscope to look for damaged paper fibers. Okay, I admit, I made up that last one, I have no idea if that's possible, but it's more likely than brute-forcing the private key.

Is it possible to retrieve his Bitcoin with only that fraction of a private key (the balance is 1.09BTC)? How long would it take to brute force the rest of the private key?

Without doing the math, it's safe to say it will take forever and cost much more energy than 1.09BTC is worth.

Hi guys,

A friend of mine just popped into my house yesterday and gave me a piece of paper with a privkey of BTC wallet. The thing is that it is old-washed paper and I can read only the first 9 symbols of this string.

In which format is said private key?
