No one can say exactly what will happen to the crypto currency in the future. It is possible that the Crypto currency will develop and will soon replace the money we are accustomed to, perhaps the crypto currency will disappear and will remain in history as another bubble, it is possible that something more technologically and stronger will replace the crypto currency.
I completely agree with you, it's hard to say what can happen, because this is an unregulated market, all run by big players!
