I've been using BTC for a while. I've been using it at exchanges, to trade altcoins and to order goods over the Internet, but I've never exchanged BTC with someone in front of me. At a store or between friends, or family. This despite having had long conversations about BTC with various kinds of people, and attending a few meetups.
Who has exchanged BTC F2F?
I did it twice if I am not wrong. It was in 2016 when a friend of mine wanted to gamble with bitcoin but since he was a new member at that time and don't have any account yet at my local exchanger, he asked for my help. I sent him satoshi and he gave me some money directly from his pocket.
