If that's a problem for you, then simply don't buy in the bull market, unless for short-term speculating, and accumulate coins during bear market. A lot of investors who joined in bull run are likely going to take profit during the run, instead of hodling for years and experience a crash like in the past. Risk and opportunity always go hand in hand, the point of investing is to find investments that have more opportunities than risks.
I agree. Buying in bull market is not good decision to when you dont see opportunities on what you invest. Price has pump and drop and even year way back, the market is the same the best thing to do is to hold since many institutions are also in bitcoin which is an opportunity that it wont stay there. Market price will be more better. Opportunist takes opportunity but risk takers stays on what they have and take chances to add more while in drops situation.
