Nobody can tell when will be dump. I think there is no strategy to protect about crypto market dump and you know that cryptocurrency is very volatile.
I think it is depend on the demand and buyers buy and hold then crypto market will be good.
Yes, if you are an expert on the market, it is impossible to analyze the market when it is pumped. In my opinion we can say that investing in Crypto takes a long time to hold and a little luck. If you do not have enough patience and you lose your temper you will lose money in the Crypto market.
