I meet with him, we go to internet club and he transfer the btc from his wallet to mine. And after I see the transfer I give him the cash ? Or how it should do ?
Thanks
This is a more convenient way to buy/sell your bitcoins. Localbitcoins.com is another good website for trading bitcoins which has an escrow service and ensure safe trading too.
Localbitcoins.com is the only website I know that you can trade for cash directly. Here is a good guide on how to do it.
