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 
Yes, I also think that it is unusual thing to happen on btc market. BTC is already popular this days but how come the price is falling down non-stop. I think it is better hold now and wait for the price to stabilise a bit.
