Personally, I see the future without fiat money, but a full cashless settlement. The Internet currency is the currency of the future, there will be a word behind it.
Got some point. I cannot also see the future of cryptocurrency being just a market for investment. It has a huge potential in which it will not suite being investment rather it will be okay if it will be a currency. But still if it happens then the measurement of the value of the bitcoin will vary of the fiat.
