Maybe I'm old-fashioned and trading isn't something I'm good at (day trading), but if I bought 1 BTC in 2015 for $250 and sold it for about $50 000 after 5+ years, how much money did I make each year? Some will say "where's the excitement in that?", but I wonder if some people are trading for profit or something else?

OP may be one of those 5% who are not greedy and has a plan to slowly achieve their goals, but tools themselves do not generate profit, I guess that is clear to everyone.
