No one can tell the exact, or can predict it.
Instead what we can do is just calculate and predict it by evaluating the situation.
In my opinion, if you seek for extra profits or become too greedy, then eventually you will miss the best time to buy the coin.
I just shared a similar perspective a while ago. No one can be that shrewd as to continue to wait for Bitcoin to fall deeper that it's doing now. It has already offered its fans enough discount. Yet, those who wished they had bought in when it was $50,000 or $40,000 or $30,000 still dillydally on it now that it's below $20,000 aren't smart. The best option and strategy for anyone interested in getting Bitcoin or other alts of their choice should be to DCA on them right now. Investors shouldn't be too greedy to squeeze out every juice in terms of cheap pricing from every project.
This is especially true when bitcoin fulfills our predictions, it was not long ago people were thinking about bitcoin reaching 250k or even a higher price and while it did not happen it still reached a very respectable ATH during this bull run.
Is it going to make any difference if we bought at 20k or 15k years down the line? Except for some additional profits the answer to that is no, the moment to buy is now and anyone not doing so waiting for a cheaper price could regret their decision in the future, as even if a new bottom is reached there is no guarantee they will recognize such drop as the true bottom and they could waste their chances of investing in bitcoin for such a low price.
