Hi everyone,
Recently I got access to an encrypted wallet.dat which contains 4000 Bitcoins. The problem is, the wallet is encrypted, and I don't have the coding skills to brute force it. Therefore, I am looking for someone who can help me with this. I know that the password is 9-10 characters long, contains "r", "u", "@" and "." and I know that the password is an email. Is this even worth decrypting? Or it is impossible to get the password just based on this information?

Any help is appreciated. Thanks!
