If you lost money when the market crashed 3 weeks ago, you are clearly not cut out for this, everyone's portfolio fell by at least 25% in a very short time, the important thing was, what did you do with that crash?

If you are negative it still means that you apply a lot of emotions in the market, I recommend reading psychotrading books

If you are in positive, excellent risk management, don't fall in love with any crypto, this is a job, we go in, we do what we have to do and we come out with more money.

They already know it!
