Bitcoin should be pushed as a dominant global digital currency
Can bitcoin be pushed from where it is to where it is?
Is bitcoin a digital currency? Yes
Is bitcoin used all over the world? Yes, even in China.
Bitcoin is also decentralized. Difficult for centralized authorities to control.
I do not see any other currency that should be regarded as global currency than bitcoin.
The problem in this world now is only about permission and not being allowed by a country to use Bitcoin as a currency that can be used. Some countries still don't legalize Bitcoin, and I don't really know about this, actually Bitcoin is very decentralized but why many countries still don't legalize it maybe there are several factors that influence it.
Until now there is no global currency other than Bitcoin, maybe I don't really observe it about global currencies now, but I only know that there really is no global currency other than Bitcoin. I think I have the same opinion as you.
