Before every order, I deliberately remind myself to be neutral, objective, and not interpret the market based on desires or emotions. I don't 'like' any altcoins. However, as long as its trend is simple, smooth, and allows me to make money, I will continue to pay attention. Taking DOT as an example, it has smoothly risen after several oversold signals. Since it has past statistical advantages, according to the assumption of technical analysis: history will repeat - then it is worth continuing to pay attention to.
