Just hold and dont panic to sell just because things value are down. actually take the opportunity to buy more coins while they are down. The entire cryto-market is in a protracted downturn, but once that downward pressure is removed, I expect most of these coins to bounce back. The rule of investor is to buy on the way down and sell on the way up and never in reverse. Cryptocurrency markets are unpredictable, hence subject to a great risk. So donot invest beyond your limits.
