On the other side, many investors are afraid to buy during dip because of further price decrease. We can't pin point the real bottom so the best deal here is, if you can afford the price (since it's way cheaper compared to ath), go and fill your bags. Anything can happen which means the price can rise unexpectedly.
Investors whom there major aim is to accumulate for long time holding shouldn't be influenced by the price of Bitcoin by knowing if actually the price will dip more or increase the more, is obvious that the goals of every investors is to make a good profits in the future but however since the plan is for long time holding I see no reason why investors should consider the current price of Bitcoin before accumulating.
That's why DCA method is there to guide investors, that it doesn't matter how far Bitcoin price has gone but what matters is how you could be able to accumulate consistently with the little funds you could afford as well as risk management, perhaps with this we shouldn't be bothered about knowing if the price will drop to the bottom or not but instead we sees every price as an opportunity to keep accumulating.
