Well I don't fully understand your article. Of course when you trade only 10% or maybe even just 1 % make money. Everyone knows that. The less you trade the higher the probability you are trading profitable. It is something I'm saying as well. And also people know that I'm only trading bigger swings which so far went great.
I agree that BUY & HODL is the easiest way to profit in the future but it's NOT making you more BTC. The only way to get more BTC is to trade or add risk in general.
