Bro, it's not possible dealing without paper money, it's the bedrock of any monetary policy in any nation that's why some sectors doesn't accept digital means of payment in their business, there's a reason why. Everything must not go digital even if people is saying digitalization is civilisation bla bla.
Europe and other part of the world is not Africa where the world seems to be darker in terms of technology. Businesses has advanced and technology is the order of the day. Come to think of it which big business tycoon moves about with paper money this days when they go for their business trips? Even a petty business trader takes caution by not going on a business trip with paper money to avoid been robbed on the road
That is an insult to Africans but I like it because that is what African leaders want. But what Josefjix said is very much correct. Business tycoons are not carrying physical Cash around again because the world is digitalizing it currencies yet the fiat currency is still used in the digital arena therefore, we can't do without the fiat currency be a cash or online (digital), and bitcoin was designed to help the fiat digitally by using it to buy things online and paying services but the store of value has taking over the coin so nobody is care about the use of the real p2p of the coins which is buying and selling of goods and services online. Even now, we sell our coins to fiat currency digitally before using to buy things and paying for services either in Cash or Transfer. So Josefjix is 100% correct.
