Bitcoin is going to be main source of Payments, paper money will get disappear and there will be no more printing of papers 💰💰💰
What are the basic things that make you think like that now?
Do you know the number of people living in this world who still use paper money every day? And one more thing, you also need to know how much supply of Bitcoin has been circulating and has not been circulating in the market for now. Because if you think that Bitcoin will be enough to be used by all people in this world, I think there is something wrong with your thinking.
Why, because Bitcoin can still be used as the main source of payment without having to eliminate paper money from this world, besides that paper money that is still used by all humans today can be a payment option when someone doesn't have Bitcoin or other digital currency in themselves. So there is no need to eliminate paper money even though there are better payment solutions available for everyone to use.
That's wrong thinking in my opinion, because paper money will never disappear, the majority of people around the world still depend on paper money as their activity.
Bitcoin will only be a second option for further payments, even though in this payment it will be easier, but there will still be a lot of opposition, including some from the government as well, but if you think about eliminating paper money, that is the wrong thought.
So in my opinion those two should coexist as a good solution, and we know some countries have adopted bitcoin but not completely fiat money will just disappear as a simpler shortcut to bitcoin and more mainstream fiat money.
