I think that bitcoin will never be known to the whole world. He will remain popular only among some people. And this percentage of the population is not very large. Therefore, bitcoin will not become a global currency
I fully agree with this.
Bitcoin is becoming very popular, but only a small portion of people are really using it. None of my friends I know IRL uses bitcoins, and I'd never imagine my mom using it even if it became a currency of my country.
