If you have remaining coins in your wallet hold it. Dont sell it until the price goes up again. Dont settle on less profit, aim for better profit. Wait till the price can give you your desired profit. If you have enough money, its good to buy more coins and add it to your remaining coins. As long as the coins is in dip and you have enough money, keep buying more for a better chance of having a big profit when the price goes up again.
