Bitcoin is really a true currency/money. Why? because once you have it you can convert into a real money according to country you belong. And the banks also accepting bitcoin whether you are in different places of the world. In that case it shows how bitcoin is very popular in online business.
I also do believe that bitcoin is money. It does not just sound money but it is a way better form of money itself. Bitcoin is a crypto-currency which is definitely have a value or price which increased and decreased because of the sudden movement of stock following the principle of law of price and demand. And I can say that it is better form of money because its transaction is can be made on the internet or web which can make transaction faster than ever and in a reliable way. And the development of its price make also be a factor that can be used in investments.
