Bitcoin does fulfill all the criteria of becoming an investment, it is just more volatile than more traditional forms of investments. People will eventually start to look at cryptocurrencies as a highly lucrative form of investment where they would like to lock their funds in. In many countries there is a currency crisis, or in some, people have stopped looking at real estates as a form of investment due to the blatant over valuation prevalent in the market. Cryptocurrencies would certainly emerge as the people's choice in the future.
