Probably not - buy & hold is a better strategy for most people, but I would add a preface that in the crypto market, it's not that unlikely we see a drawdown in the ballpark of 80% again which trading can help prevent or mitigate. It's not like stocks where you can be certain they will go up in long-run: Many projects will fail (even the ones that look higher quality). However, I'd keep an allocation to the space and make sure your position size isn't so large that you are risking your financial independence on a market that is so overheated.
