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)
I think that in a short time, Fiat money will go into digital. You will pay from your phone or card. Soon you will have cryptocurrency on your card. This will happen in about 2 years. by 2020, approximately. I think that the UAE, Switzerland, Japan will be the first to implement this.
