Simple Formule by the Great Warren Buffet sir.
Buy Right And Hold Tight

Thats Enough.
Yes it can be a best trategy for an investor but for the traders it can be little different since they have to read everything about crypto currency and act based on it,
I agreed with what you said because crypto investors just follow the market while crypto trade deal with the market every day and the way to handle tough times in crypto currency is not been greed, knowing the right coin/the right to invest, be patience and exit the market at the right time.
