I often see topics like this and I have one question,From where should people know about this?They  have trust because its a new revolutionary system in financial instution and I don't understand what will the problem if price goes down? If you don't have trust in bitcoin why don't you sell it now? i believe that if price goes down it will rise up in the future,But if you want answers you must say what are you going in the future,Are you day trader? if not learn more about bitcoin-blockchain technology,if you know better currency than bitcoin,buy another one,its no problem,the price is determined by the possibilities.
