i think it is normal, maybe i can give some explain. bitcoin is a center of crypto currency, whatever happen with bitcoin, the altcoin will get the impact too. so if bitcoin price is increase, altcoin price will be decrease and this will happen with the other side. when we see bitcoin start to climb then we should aware and prepare but don't afraid because if altcoin down, i am sure the other time, the price will be recover like what bitcoin do.
