Yes I think that cryptocurrency can overtake fiat money in the coming future.It is easily operatable and can be used by everyone.Cryptocurrencies are getting really very popular these days.Since no central bank has control over the cryptocurrencies,the people can get full profits and taxes can also be escaped.For cryptocurrencies,you just need to have an internet connection and some basic knowledge about them.Bitcoin is at the top of the cryptocurrencies.The traders are also accepting bitcoin for trading.People cannot carry huge amount of money everywhere.Bitcoin wallet or blockchain wallet is the solution for carrying a huge amount of money.The privacy is maintained and only the receiver and giver know about the wallet.
