I do not expect it to reach the ATH. To repeat 2017, so many people of the world would have to invest. The big mass of people have already bought and sold again because of the dropping prices and disappointing feelings they had.

So you cannot have a 2nd big fomo like in 2017 if it has already happened once. There can now only be another huge investment round if Bitcoin or an altcoin develops in such a way that it is very practical, very safe and cheap to use. And if people have a reason to doubt the existing economy due to the effects of the corona virus for example.

The halving event can add fuel to that but not much I think. Because many have either already invested or do not believe in it anymore.
