i think Technical analysis & psychological analyze both of most important parts in the crypto trading, because trading is also psychological game, if you can't control your emotion then high possibility to loses everything, psychological analyzing can protect you from greed.
I would say it is even more important than the rational of analysis and charts, and the OP has also pointed this out. What is not often stated in all the marketing of trading is the percentage of intraday traders who make money over the long term. They should be forced to put it big in every trading ad, covert or not. Things like psychology or that stop losses do not always work, are more important than a supposed system that they try to sell you and with which 95% of people or more lose money.
