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?
Selling your coin in the market is the safest way to do because selling it on the real world is very dangerous because anyone can take advantage and you may end up having a bullet in your head by having transaction into stranger.
