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?
Cryptocurrency will not fully dominate the world currencies where most of the countries think it is their anti financial policy. Crypto currency developed and spread in maximum corner of the world and will spread more but it will not be the main stream coin of the world. If Govt of the maximum or all countries think and take action to legalize Bitcoin, then it can be used as the 2nd money of the world where local currency will work with it.
