This is an individual question. Someone collects everything as an old grandmother, and someone acts according to the situation.In such a rapidly changing market, I think this will be the best solution.Very often I kept coins and tokens and waited for them to grow.And very often it was in vain.They further fell in price even more.In my portfolio there are assets that I consider to be long-term. Let's see in vain whether I do it or not. So far there is no answer.
