Im pretty new selling bitcoins. I want use that localbitcoin site but question is: how i can know who buyer should i sell bitcoins because there is alot buyers?
make sure they have a verified account and check their feedback
LBC accounts seem to be regularly bought and sold these days, including verified and even pro accounts.
Jezze, what payment method are you selling for? Be very cautious with anything that can be reversed or if the buyer tries to get you to deal outside of LBC, without a trusted escrow. It's worth remembering that positive feedback means nothing when the account has been bought.
