Mats problem is that he is stuck on the idea that the only right way to make money is to daytrade. Realizing that he sucks at it, he doubles down and loses even harder.
Meanwhile I just made a hundred bucks in two minutes by buying on localbitcoins and immediately reselling on kraken. There are plenty of ways to make things work for the open minded.
In-person or purely online?
I always deal in cash in person, on principle. I want as little middleman involvement as possible (banks, other third parties) and I don't like "paper trails". Personal privacy is one of my big issues.
And how, if I may ask, you deal with BTC pseudonimity? Are you so paranoid to keep everything separated, un-linked (with mixers etc.)?
I would love to have a more fungible bitcoin in this case.
