What really would make it difficult is that if they sell more bitcoin than they have. Right now banks have the right to loan out more money than they can and they even buy shares and stocks of companies as well, so they get only a a certain amount but basically feel like unlimited amount of loaning out and investment with a lot more money than they have.

I am super afraid they will do the same with bitcoin and CBDC type of stuff, it is a start and the moment people start buying so much that there will be 25 million bitcoins loaned out or invested into, people will realize that is not even possible but it is going to be too late. I don't know what to do about it neither, we just have to educate people not to do it and it would be basically hurting their own finances but we can't stop everyone.
