I think, it's not easy to be a holder, especially, hold bitcoin in a very long time, and that is hard to predict.
even panicked holders are part of the factors that make bitcoin fall drastically, from $ 20K to $ 6K today.
but, I agree with you, that the holder must be calm in facing every FUD.
if you feel that there is no gain in holding it still calm. take advantage of the opportunity to trade in the short term, you know prices go down immediately buy and if you know the price goes up immediately sell so you still get a profit.
