It is impossible to unambiguously answer this question. There are a lot of nuances in holding a cryptocurrency, just like in trading itself. Let's start with the fact that holding a cryptocurrency as a whole is not an end in itself. When holding, we still assume its sale at a certain price value of this cryptocurrency. Those who do not have time to do this in a timely manner, lose the opportunity to make a good profit. So, many probably now regret that they did not sell at least some of their cryptocurrencies when Bitcoin was at its peak price of $68,000 last year. Now again it is necessary to keep it until the next such opportunity, which may appear in the next year or two.
Cryptocurrency trading is riskier than holding it. Here you can get rich faster, as well as get losses faster.
