so somebody is offering me bitcoins ridiculously cheap. and he's probably trying to scam me. but it's too good of an offer, i have to see what's up.
how many confirmations is safe? (i'm buying 40btc)
i'm gonna meet him in a bank to be safe. and not gonna hand him any cash until i get the btc.
anything i should be concerned with?
Well 40
BTC is big amount for me, i think 5 confirmation is enough until bitcoins be received with save on your wallet. If everything went fine then you can give the funds to him. It is more safe for you and good luck.
