Nobody knows what to expect from two things: crypto currencies market and Donald Trump 
I would not wonder if he would say that crypto currencies are great in his next speech, so keep calm and let him talk.
That is hilarious. Well Mr. Trump is a businessman and this cryptocurrency has been pretty much profitable for people in the US. Their major banks like Goldman Sache and many more have actually started accepting Bitcoin transactions. The leading companies are accepting Bitcoin as a medium of exchange and to cut down the cost of their economic activities. Do not follow what Mr. Trump says. I would not wonder if he would say that crypto currencies are great in his next speech, so keep calm and let him talk.
