for now if your coin is still profitable then sell right now. if not profitable then hold your coin.
this btc decline is only temporary, btc i predict will be at peak in july 2018. so be patient
I wont suggest selling out right one for two reasons. First, we are not in the pump phase so no big profits or even profit can be earned. Secondly, a very bright future is predicted and soon all the coins will be gaining value. That will be the right time of selling out. Holding is what everyone should be doing at the moment, beater is to trade or buy more coins. Dips and recovery phases are basically for giving a chance to buy digital assets at low rates.
