Few years back, I could remember Cryptocurrency wasn't really known by most people and the idea was joked with, even I myself didn't have a thought on it, but the growth of crypto is now alarming that almost all my friends are into one or two of it. Looking into the future I suggest Cryptocurrency will suspend other past used currencies and take over, what do you think?
Many threads about crypto replacing fiat has been posted long time ago even in 2017 as I register my account here.
Thing is no. Not all people will get along with technology properly. It will cause trouble to any sort of market you can imagine. This is also why we get slow adoption as well in some coins, but it doesn't matter that much. As long we have some top coins to trade at, there's nothing to worry about this so-called "bright future".
