I think it's safer, faster, and the country can save on the cost of printing their own country's fiat currency. we all know that the costs a country has to spend on printing their currency are very expensive, and cryptocurrency is the solution...
Exactly. This is a hypothetical scenario that if all the countries converge to the crypto, it will bring much economic prosperity but that would indirectly mean letting go their existing wealth which no country would.
The funny thing is that governments could bring that prosperity to their people if they wanted to do it, while bitcoin is a huge step forward when it comes to the technology the truth is that most of its value comes from the simple fact that there is a very small amount of bitcoin in circulation, so if countries just adopted that attitude of not printing as much fiat as they wanted they could make their countries very prosperous.
