Whether or not the electronic money through the future is easy is a difficult question. Firstly, in terms of economic integration, this is very difficult now because each country has its own face value and money, it is difficult to synchronize, another difficulty is that the legal is unclear because each country has one private law. Secondly, the political, military, and information technology are uneven, leading to access to electronic money is not virtual reality. So how to solve this problem?
As bitcoin is decentralized and censorship resistant, it's not clear that countries can do much to suppress it in the long run, especially as their currencies fail. Should the bitcoin price reach astronomical heights, the people will be able to buy it in fractions, or satoshis.
