In the future far from now the paper money will disappear because everything would be digital and nothing will go with paper things anymore.
Its just a matter of time in my eyes.
Do you think your eyes will still see that happen? I dont think so. Why is it that so many people are so damn being Nostradamus whenever they got hold of an online money. Be real. Dont watch too much movies. Go outside see what is really happening in the world.
Paper money will always be paper money and it will not disappear in market circulation. Bitcoins is good and the digital world is good but we have to admit that everyone cannot use digital money due to lack of education or they just don't simply benefited in using it.
