You can print more crypto. You can't print more Bitcoin. You could make a competitor to Bitcoin, and thereby print money that way, but it takes energy. It takes energy to make new Bitcoins. And people can't use their energy for two things at once, they have to pick one.

The more Bitcoin secures itself the more the other crypto gets pushed out of the mining market.
