Bitcoin isn't a legal currency for now, and I just heard some news that they're stating that this bitcoin is a whole scam, wherein I dint wanna believe, really. For it has proofs. And so, maybe if people do really recognize the real service or importance of this bitcoin then maybe there has to be change in currency for now.
Not all Countries accept bitcoin as currency. Some people claim that bitcoin is a very dangerous currency. And this is very different from my thinking, I think that bitcoin provides great benefits and brings great changes in the world of economics.
