I think it's true bitcoin will be the currency of the future and will replace the paper money but it will happen because there are still many countries that do not let the bitcoin.
I don't think it is the future of money i think it is just a way of payment system. Although Its true that bitcoin price is really amazing amd many has started to use bitcoin because of its price. But it doesnt mean that bitcoin is our future currency, There is a possibility of banning of bitcoin in every state that can cause the fading of bitcoin.
