I believe paper money will disappear over time naturally. In the same time bitcoin can overtook fiat currencies and many people moved over to that.
I agree that there may be paper money began to be abandoned by many people in the world, and probably will dominate the digital money. but I'm not sure bitcoin can replace fiat
We should be optimistic about digital currencies adoption, because many countries started regulating Bitcoin exchanges like Australia and some American states,therefore, digital money is on the right way.
Digital currencies are still developing, and the paper money at the end of its development. But still digital money can not replace paper. Many countries are not ready
Even if many of the poorer countries are not ready some of the most powerful and the ones that move most of the world economy are in fact ready to replace paper money just look a t credit cards.
People can and are ready, and the government - is not. That the government is addressing the issue. In many developed countries have not defined the status cryptocurrency
Nope only a few "chosen" people or users are ready to use cryptocurrency. The main reason is the connectivity issue. More than half of the globe population have no access to internet. Let alone that only a small percentage of internet users are aware of cryptocurrency, You can try to survey that and they will ask you about "What cryptocurrency is" . So in my opinion if the government wanted to replace their currency and use digital currency such is bitcoin, they need to improve and make their country population to have 100% internet access.
The future of paper money will be still the same, it doesn't make since if in the future paper money will vanish, because not all people have an internet access there were people who are living in areas not covered with modern technology specially communication. They were very particular of using the paper money and its very convenience for them compared to those who are having internet online account for their banks. If it happens that papr money will be gone, it should be mandatory for the government to generalize internet access to all areas around the world and then introduce trainings which that would take a long process to follow.
