It has been observed for just a few months at the 4th quarter of last year that bitcoin started to fall in price. Then it still dips until now. There's a reason behind this event. It might be somebody's trying to control it like another big financial group or person. But I can't prove that it's only a matter of opinion to how this trend had been going. Hope that it can cope the next succeeding days, weeks or months. One thing I know that falling down is bit by bit with bitcoin but when it rises up, it's like you are going high to the sky it will bounce back very soon.
