Can`t agree that crypto trading is not very difficult. And it definetely requires more than you suggested. It is not enough just to understand what is happening in the market and be able to learn. It is necessary to quickly make decisions, analyze your mistakes, be able to draw parallels between past and current situations, be constantly aware of the news and have a stable emotional state. The combination of these factors is quite rare, so not everyone can call himself a trader.
It is not difficult if one can have that time to know things that will make it easy. Getting good understanding about crytocurrency is time dedication. Nothing is too hard to know or understand, decision making is what will help to achieve what desire to know about crytocurrency.
