Many Say Cryptocurrency Will Kill Fiat Currency and Creating FUD all around the Internet, According to me if this statement is correct then CR.CARD Dr, Card has done this Long back, Cryptocurrency will be used by Smart people in future and many businesses will opt this for fast transaction
It's not easy to kill cash because still many people don't know and understand cryptocurrency and they will keep using Cash.
Whats your view about this
Still there many people who even don't know how to use PC and internet in so-called "Third World countries".
So I think that cash can be killed only in highly developed and developing countries.
ps. I don't understand meaning of your bold words, you could write your thoughts more distinctly.
