Bitcoin is not SCAM. I think bitcoin does not fool anyone, bitcoin makes a profit and helps to minimize time and transaction costs quickly. People use bitcoin to scam other people. Scammers are everywhere and you should be wary of them everytime.
I think if you want to invest, we have to trust people who have succeeded in bitcoin and that we know.
bitcoin is real, not fraud.
it seems like such people will be much more by 2018. so I think we should know more about BTC.
