Selling my multibit wallet holding 17.17BTC.

The wallet is locked and the passphrase is forever gone!
I changed the passphrase to a new one due to a suspected virus (shitcoin wallet download), and the second i copy-pasted the generated password in notepad my PC crashed.
I've tried every possible or known password recovery method, and have payed over 5BTC bounties so far for people to try and break it. I even had my SDD scanned for some clipboard data.

You'll get:
The .wallet and the .key file for the wallet
The length and composition of the password (i know the settings of my generator)

Best offer is accepted, since they are lost to me anyway. Do you feel like you can crack this unknown password? Hoping for some quantum computers soon? This is your shot!
Escrow accepted at your own costs and efforts. Escrow agreement is to release the coins once i've transfered the .wallet and .key file.

Wallet address is available on request only.

Starting bid is 0.5BTC, minimum increments of 0.1BTC
Private bidding is allowed.

Good luck bidding

Iam interested. Could you please send me via PM the BTC Adress and the numbers u think the passphrase contains.
regards

I could break if it's under 90 bits of entropy (I have a large network of comps ...)

Let me know how long it is, how many numbers, caps ,etc

If it's more than 90 bits of entropy you're gonna need NSA level capability!

How long is the password? I will never bid if the password length is above 15 characters.

I think the idea is that you, like, pay for that info.

The passphrase itself is relatively short.
Yet it has proven to be unbreakable until now.

What do you consider as 'relatively short'?

Need a Bitcoin address to verify your claims and have you tried hacking yourself ? How much time have you spent of trying to get the password ? At least tell us how many characters it is.

Walletrecoveryservices.com has tried for over 3 months cracking it.
btcrecover script (https://github.com/gurnec/btcrecover) is trying to crack it up to date using 4 GPU's.

The passphrase is 9 characters long. I know i've set the generator at +1, and default length is 8.

Alright so this is really one for the NSA to crack. 3 months and no luck any chance of the Bitcoin Addy to check the balance ?

Address send in PM. Like stated in the OP, address on request only.

The address that was sent to me did indeed have over 17 BTC but then again he could have sent me any address.

Watching.

I am interested in this.
Can you PM me the Bitcoin address that holds the 17 Bitcoins?
Is the password alphanumeric or does it contain special characters?

He resent me his address in the form of a Print screen and it shows his wallet in Multibit which apparently can't import watch only addresses.

interesting :) as there is no guaranty that you will not keep the wallet and try to recover the password on your own you should consider turning this auction into contest with bounty

Anyone could try to crack the password with this tool: https://github.com/gurnec/btcrecover (https://github.com/gurnec/btcrecover)

Read OP please.

i've read the OP, there is plenty of gpu farms and people with access to 'free' computing resources. 9 character password is crackable http://www.ntsols.com/newsletter/ezines/issue23/9-character-passwords-no-longer-secure.htm (http://www.ntsols.com/newsletter/ezines/issue23/9-character-passwords-no-longer-secure.htm)

Print screens can be faked. There is no guarantee that the OP does actually have the PW to the wallet and that he will spend the BTC once he receives payment for the wallet.

IMO the OP's best bet would be to give the wallet to someone he can trust and that has the resources to crack the PW and then have that person agree to send the OP a certain percentage of any BTC that can be recovered.

You mean like i did about 3 times now? Read the topic before posting please, it has been stated what efforts i've done so far.

I read the topic. I am saying there is no guarantee that what is written in the topic is the truth. I am merely telling you what is most likely going to result in the best outcome for you if you are acting honestly.

Current bid via PM is 0.7BTC FYI. I'll see a day or two if anyone goes higher, else i'll sell it to that person.

Reserved and awaiting escrow.
Thank you all.

the password is under 50 bits of entropy .. i could crack this in 2-4 weeks and will split 50/50 with the OP. I will not pay for the privelege to do so however :-)

is it already sold??

It's reserved but no news from the buyer

Confirmed to be back on sale

brutal

It was obvious from the start this person was just out to get the files..
Never trust new accounts with sub 200 posts here...

So back for sale, serious buyers only.

we can crack together, 9 words the paraphrase will take 2 or 4 weeks


44% fee

let me know

Edit 9 letters

 ;D ;D

If this is a real offer, and you are successful, please post here and let us know. This would be a shimmer of light onto the cryptocurrency community.

Agreed. Like stated before, several users doing nothing but recovering passphrased went trough the trouble for several weeks/months without any result.

I will not share the wallet with anyone, because that means, if they manage to crack my passphrase, they can simply empty my wallet and vanish.

This post is an auction. Place a bid if you are so confident you'll crack it, simple as that. It will gain you more than 44% if you manage.

Didnt you say its a multibit wallet? Btcrecover does not support GPU accelaration for multibit. 4 CPU cores do ~360kP/s though with 2⁹⁰ combinations we are talking ~ 10¹⁴ years. Even if you split the work among a million machines chances of finding the password are very low.

I dont think anyone will buy this.

Exactly my point. That's why i auction it. Read OP.

I think contest with bounty isn't a bad idea. Escrow a bounty, publish the partial wallet information (extracted with btcrecover extract scripts), and let people try to crack the password with btcrecover. Set a deadline (eg one month). If nobody cracks the password, sell your wallet. Since you consider these bitcoins are lost, you have nothing to lose.

I'm not intrested in waisting my time holding contests, sorry.
If nobody places a bid, i keep it. If anyone wants it, you can PM me.

keep it then. good luck with the coins hope you get back

Sorry, I don't have 0.5+BTC to buy a pig in a poke.
Still, I wish you good luck.

You can always rent a 30,472 core super computer for $1279/hr.

If BTC goes up to $500+ I may be interested in this auction.

I would take the offer of HotSwap. If he really could crack the 50 entropy password within 2-4 weeks then this is the best deal for you. I would give it a try.

I would make an offer if the start bid was a little lower.   I am interested, and have a few ideas, but they are all long shots.

So what if i make this a challenge combined with a lottery?

Brainstorming:

I send a copy of the extracted keyfile for let's say 0.05BTC
Everybody that 'buys' the keyfile is put on a list, and if someone manages to crack the passphrase, the contents of the wallet get divided by all those users.

More than likely most would just buy a spot on the list and do nothing.
Small price to pay for a bunch of BTC

what about you publish extracted data and anyone who cracks the password would 'blackmail' you for bounty, simple :)

That's what i'm trying to avoid  ;D

nothing bad about this in my opininon, you could get to media with such competiton, you could end up with multiple users who solved the password and you just pick the best offer :)

Good idea, but there have to be minimum - something like 1BTC

That's way to steep.
