Private key of BTC wallet

[PawGo]

If you have 9 characters only, we may say it is undoable.
 If it was a paper wallet, chances could be increased by (even partial) QR code etc, but knowing only 1/5 of the private key makes problem unsolvable.

If you have 9 characters only -> we can make a lot.

publish the address first then we can talk. I can help

Bullshit and you should know it better! What you're claiming is simply dishonest.

As OP stated in his post only the first 9 characters are visible. Without the encoded checksum at the end you have no way to limit your vast search space. as nine chars at the beginning aren't such a big limitter. Nice try to lure the OP to reveal details he shouldn't.

I do not understand. firstly - I'm asked about bitcoin address -> not for "part" of bitcoin privatekey:).

maybe I can help him or maybe not. and it is not lure. really I do not understand:)

No one will be able to help OP find the private key and Cricktor is completely right. OP posting his/her BTC address will be also useless.
No offence but, does it make any difference how much bitcoin OP has? Does it matter whether OP has 1 mBTC or 100 BTC? How can knowing OP's BTC be helpful? Does OP's bitcoin address give us any information about its private key?

we are not talking about how much BTC are in address, but how many transactions are out. then we can talk. If you do not understand -> do not issue "post"

What do you mean by "but how many transactions are out"? Are you talking about inputs and outputs on the address, nevertheless it has no connection with op's problems, neither can it help them find the missing characters of their private key. If i may ask, how do you intend to use what you are requesting to get the missing characters?

Obviously he wants to check if the public key is known, if you have the public key and a few chars of private key, it can greatly help you finding the private key, but success is not guaranteed.

Any information from transaction amount history to even public address didn't help finding the missing characters, but I'm sure he would have wanted to ask 9 characters from the OP to try his luck accessing the wallet, but that wouldn't work. I doubt the wallet owning 1 BTC doesn't have the security to keep private keys safe and he just writes on paper, he doesn't backup private keys or prints private keys on paper paper has been laminated or writes private keys on metal objects. Any attempt would not succeed unless he saw the clues of some of the characters on the paper using the help of props.

Sir, I want to ask about your software using CPU or GPU when used? Please your answer.  

As of now, it doesn't have GPU support but it's in the roadmap.

You can follow his tool's development in its GitHub repository, here: https://github.com/Coding-Enthusiast/FinderOuter
And here's the Roadmap which is aiming for GPU support in version 2.0: https://github.com/Coding-Enthusiast/FinderOuter/issues/47
Current release version is 0.18.0

OP, forget about the 1.09BTC since you only have 9 words. It is better that your friend should let go of trying the find the others because it is a mission impossible. If you can use the link @Lucius gave and ask the company if such is possible,but if no then nothing can be done,since you said that you have even tried using a microscope. As for me I think that the probability of getting the missing characters of your private key is zero.

OP, forget about the 1.09BTC since you only have 9 words.

The OP states that only the first 9 symbols of the private key are visible. I read this as the first 9 characters of usually a private key in WIF format on a faded paperwallet. Be it aged or fabricated, well that's unknown.

Now that I think of it, I find it strange that no QR code or traces of it is visible. It it quite common for paperwallets to include a QR code for quick and convenient read-out of public address or private key of a paperwallet. Nobody wants and should have to copy a WIF key by retyping it by hand, that's absurd.

How is the amount known of the public address which corresponds to the only partially visible private key? Well, it could be written on the readable part of the paperwallet. The OP just mentions it without further details and AFAIR none were further asked in the thread as it turns out it would be basically impossible to brute-force it.

Glimpsing again over the thread, I've a feeling that there's still some lack of details, but chances are very very slim. You would need more details like the public address, hopefully an exposed public key in the blockchain, be lucky with some more outgoing transactions that the corresponding public address was involved in.

I'd still say from gutt feeling: it's a lost case.
