of course it makes sense. if you start with 50k many years ago you are not performing better than placing random bets(actually much worse). It does not suggest an ability to pick coins that would be better than throwing darts at symbols. Probably worse.

If you bought stratis in september of last year for 1.000$, you would've been a millionaire if you'd sold in june. It's easy to talk about what could've been, but let's not forget that if this guy is telling the truth, he did become a millionaire by trading, and that's something we all want to achieve.
yes he did indeed become a millionaire by trading, by losing what would have been a billion dollar fortune if simply held. He bought in early in what was a future billion dollars and managed to lose most of it along the way.
