I believe every business has risks and benefits.Bitcoin is unpredictable, volatile and it's price keeps changing that is the reason behind it's fall.
Well this is true, the down side of Bitcoin is the unpredictable nature but one can't really understand or predict why the market is really back.
Early this year folks say it's because of China and USA speculation about not accepting Bitcoin, i will say with a fact that the market will rise whenever it will happen.
