Actually i sell my bitcoin last year at the month of november. I think bitcoin price at december are in between of 16000$-18500$ and obviously it really differs at the current price now at 6700$. It's been so long that bitcoin stays at below 9000$, those who invest at the month of december for sure that some of them are in doubts now. But don't be so worried because i know and i really believe that bitcoin will rise back soon and will surpass 25000$. Just keep the faith, bitcoin is the king of cryptocurrency absolutely it will recover soon.
