0.5 BTC Reward (~USD 31,000) for Recovering the Password (hashcat)
 | Back in 2013, someone created a Bitcoin Core wallet and encrypted it without giving it much thought. Over the course of that year, they deposited small amounts of Bitcoin into it. When they later wanted to cash out, they couldn't remember ever encrypting the wallet in the first place. While attempting to recover access at the time, they filled out the following form (see image). The version of Bitcoin Core available back then displayed the following recommendation when encrypting a wallet: "Use a passphrase of ten or more random characters, or eight or more words." This was only a recommendation. The actual technical requirement was simply that the passphrase contain more than one character. Today, the owner believes the password may contain the word "wallet" (or its Spanish equivalent, "billetera").
