Trading has to activate intuition of a person. I also think we have to choose the right timing to buy and to sell. For me, I prefer to do long term investment and I don't like to trade daily. Especially for assets that really great at this time like ethereum.
It's just a personal choice, because everyone has their own strategy in managing every investment they make very well because for each person choosing a certain time and duration is the way in which they set targets to be better, so it can't be done It is denied by everyone because not everyone will do the same in all investments.
