I would like to know if cryptocurrency will replace fiat money in the future, also if so how long it will likely take. Also, I would like to know which coin you think would take over if one will. (E.G. Dogecoin, BTG, LTC, XMR)
it will never happen bro.
Even crypto cheap, fast and good enough but there will don't have any government use it instead of fiat. because they can't control it.
