Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it
Pollard Kangaroo approach is for the know private key range and for the best, within 125 bit range and of course since you have the Multibit wallet handy all you have to do is "Once you located the files, if you have access to an old multibit app on you computer you need to import the wallet and export the private keys to a new wallet. If you do not have a copy of Multibit, you can use OpenSSL together with your password to decrypt the files and recover the keys."
You need the password to export them. I still have the wallet open every single day since then.
I just keep looking at what value I've missed out on
The difference between your case and the puzzle is that we can't know the specific bit range just by looking at the public key and transactions from your pubkeys can't tell us what range the private key would be or else all of Satoshi wallets with exposed pubkeys would have been emptied by now. The best we would need to do is scan from first bit all the way to the end of the 256 bit range which of course would be like trying to scan for the wallets of Satoshi with the 50 bitcoins from the early mining... wouldn't pay off stilleven if you are able to scan for 1 wallet successfully, you'd need funds from 10 of those wallets to scan for just 1
