Bitcoin Wallet password, which is the best method to recover ?

[Snoopy]

you could try

hashcat -a 3 -m 11300 wallethash2.txt -1 ?l?u?d  --increment --increment-min=10 --increment-max=12 ?1?1?1?1?1?1?1?1?1?1?1?1

but cracking wallets with bruteforce ... well you have to be very lucky to be successful
