In the future, paper money will disappear, it will be replaced by another currency. In other words, paper money will become worthless because many countries print more money to stimulate the economy, the value of paper money will decrease serious. And i think electronic money will be the main currency in the future because it safe, fast and ensure transparency
No big difference. Any physical object that will replace the money will bring the same problems. In the digital money is not for the problem. Paper money will be a very long time.
One major problem with digital money is that the government can just add more funds on their wallet whenever they want. They own all of those money, then of course they can do whatever they want. It's basically the same thing as what they do with paper money. The only difference is that it's much easier to do in digital money. They only have to add some numbers, then Voila! instant billions worth of your fiat. The value of your fiat will decrease accordingly as well.
That is why digital money should have a limit on its supply just like what we have in bitcoins or any other altcoins. Any currency that can increase in number anytime the government wanted to do so will keep devaluating because the government would want more and more money so they would print/add more quantity in their fiat money.
