Ive got a wallet with 0.7 BTC in it, I've lost my seed and cant remember my password - would it be possible to sell this to a whizz kid who could get access to the BTC or is it a lost cause
Without more information there's no way to know this is legit or how difficult it would be to recover the password if possible at all. your best chance would be to post more information and ask who can help by offering a reward. don't try to sell the wallet, it even seems fishy.
