The more the price drops, the more panic bitcoin users become, the more bitcoin they sell. It is like vicious circle which keeps making the price of bitcoin get lower and lower. I know it is distressing to lose your money because of the falling price but bitcoin has its ups and downs and sometimes the downtrend is just taking a bit long. I don't know for sure what has cause this tremendous drop in the price of bitcoin but I do think that our attitude toward bitcoin affects a lot. If we are negative and lose faith in bitcoin, it will eventually come to a halt. But if we believe in bitcoin and wait patiently, the price of it will gradually increase again. Bitcoin has gone a long way since its birthday now, it deserves a future better than this.
