2017 was a victory for bitcoin, but by the end of December 2017, bitcoin was slowly falling with drastically, the value was $ 20K, and now it was $ 6K.

if the drastic decline occurs again at the end of December 2018, then I think that bitcoin will fall $ 500.

I want to know your prediction, do you have the same thoughts as me, or do you think that bitcoin will survive at $ 6K until the end of this year. what is the main reason you think like that?
