It is very optimistic to believe in a dominance of virtual money these days. After the market had been regulated, they have fallen down. Of course, it will rise again. I personally believe in cryptocurrency. I think they are the future. We can easily invest in them and they allow us not to depend on ICO and the old system. In the future, however, I think the bitcoin dominance will be huge. It can be nearly 60% of the world economy. It will be hard to live without fiat money. People are used to it. For that reason, bitcoin progression will come but slowly.
