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 you'd better start investing in bitcoin today, because now the bitcoin price is down. This is a great opportunity, because if you already have bitcoin and then saved until October, it looks like you will get more profit. why should sell in october ?, because usually bitcoin price on that month always good.
