Most likely, we need to expect some periodic tightening of the rules of cryptocurrency circulation in society. However, this will depend on the specific state, and more precisely on the level of development of democracy in society. We see that in states where totalitarian regimes exist and human rights are violated, there is no free circulation of cryptocurrency or its circulation is too limited.
Given that the level of democracy in the whole world is growing, it is unlikely that governments will already be able to prohibit the use of cryptocurrency by citizens, but it is quite possible to tighten it up.
