Why not. Cryptocurrency is no different from ordinary money. The principle of operation is the same. There is no difference with the card, what is the bank go to the store. Now a lot of projects are aimed at the development of the cryptocurrency economy.
My thoughts exactly. The principle of operation is the same, but even better. Transactions will be more efficient, faster and even safer. Some alternative virtual currencies now, are even starting to exhibit lots of potentially life-changing features. An example of which is virie. It features a blockchain-based virtual market place that comes with an escrow system. Market entries are non-editable, non-erasable and cannot be hacked. I think money will be safer virtually, to be honest.
