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.
I think people has learnt a lot after they ignored the potential of bitcoin, a decade ago, 2009,when bitcoin was introduced people were calling it a bubble that would burst soon and a scam and then there were few people too who believed on bitcoin and now they are the bitcoin billionaires and those who ignored the bitcoin are now regretting so now who are saying bitcoin a bubble will definitely going to regret it in the future.
