You know, thats a problem we are facing right now. Its very volatile. We cant control its price so if the value drops thats a loss. But bitcoins are good because it can recover so quickly and earn back what you have loss. Its just a matter of time before you earn some profit and its worth it because you can earn big amount if you reach the higher price. I dont get discouraged when the price drops because i know it will regain its normal price.
