Money is what the society accepts to be money. Human history has seen so many transformations when it comes to the subject of money.From barter trade to fiat money and now digital currency. But some nations are so rigid to change.well they will all regret soon because no country can stop cryptocurrency.
Well.. you can't blame them since cryptocurrency today is so volatile that it is really hard to keep up with the movement specially if you want to integrate cryptocurrency in the market of your country. They will eventually reconsider once the price has been somehow regulated.
