But here is the question, do you think Bitcoin can overshadow the relevance of dollar in the future?
No, Bitcoin is now heavily used for investment purposes rather than as currency for payment that was supposed to be a rival to USD.
USD and Bitcoin already co-exist that benefits to each other. There’s no way the government that has access to unlimited supply of USD will allow Bitcoin to overshadow it.
Bitcoin is now being regulated so there’s no way it will happened.
