Because many people don't have an in-depth understanding of encryption, their one-sided understanding is something like stock. Of course, they are wrong. We don't want everyone to understand encryption, because not everyone has the same idea. There are many things in the world that you can invest in, even if they are too many, you don't have to go to those people too much.
As for whether encryption will become the currency of the future, I think it is impossible at least in my opinion, but encryption may become a currency in a certain field, which is undeniable. You must know that when a new currency replaces the existing fiat currency, the chaos of the whole world will be unimaginable!
This is some of my personal views.
