I will not invest bitcoin at the moment, it puzzles me. 2017, bitcoin prices will increase as bitcoin loans are the primary currency. In 2018 I saw a lot of bitcoin imbalances at times when it came to the point where I could not believe 
I think it is the best opportunity to invest in bitcoin while the price of it is cheap. As we can see that bitcoin price is continuously decreasing and a lot of people are stressed because they already loss huge profit. But for those people who does not invest yet in bitcoin, it is an opportunity for us to earn. I believe that bitcoin will rise up soon.
