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 not in the near future, bitcoin is still the famous, most popular and most used cryptocurrency and I believe it is still growing and finding its way to the center stage. This century will still be dominated bitcoin. If ever bitocin will be replaced, another rising cryptocurrency is the etherium and I think it will follow the path of bitcoin.
