Actually it's totally different,
even though its name was Cryptocurrency,we can not compare it to actual money aka Fiat.
if we want it to be considered as a 'real currency' we should have a physical form.
right now the best word to describe it is 'Electronic Payment' not 'Electronic Money'.
'Electronic payment' was a tool for people to help them send their money across the world,
it's just a tool and will never replace the real 'money' itself.
You got the point, many people keep talk nonsense about Electronic Money.
Fiat never be changed or removed, there is many problem if you dont have Fiat.
I will agree that Electronic Payment will change CC/Debt Card Payment.
