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.

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 Grin

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.

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

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.

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.

Where am I?

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.

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

Quote

“Offline” mode for nearly all supported wallets - use one of the extract scripts (click for more information) to extract just enough information to attempt password recovery, without giving btcrecover or whoever runs it access to any of the addresses or private keys in your Bitcoin wallet.

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.

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

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.

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

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!

No I dont escrow anymore.

-snip-
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.

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.

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.
