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 would take several long years before cryptocurrency will finally take over our old fiat money. What is certain at this time is that it will take place. There is no stopping cryptocurrency to conquer the world. This is one of the greatest social evolution that will happen in our society. And we are kind of lucky to be part of this at an earlier time. Bitcoin is the one that would lead this change.
