Like many people already said is that the paper money future is not so good because it has the digital word against.
Everything these days will get digital the world is really changing.
I dont think so. That is still far away many will happen and besides I think that it is still risky living your money online. Some still prefer it that way and physically touched.
Well for those who dont want advancements then they will still stick to a paper money eventhough technology will put it's way on progress. People are just waiting for the time that digital currency will be accepted for almost merchants around the world before deciding to switch.
