Its very important to understand risk management. Unfortunately your first experiences with crypto were during a bull market, but you were gambling previously. In Trading you cannot gamble, and do not throw darts. Always know your levels, set stops, and the #1 rule is capital preservation. I know what the low is like, loosing, but you were not actually trading, it wasn't poor trading, you were getting lucky in throwing darts.

I suggest you try not to trade but if still want to play in crypto markets behave like an investor. Did you get stopped out of everything, like were all your trades on margin?
