I don't advice now to sell your coins and cut your losses as the market is at severe crash right now. Many have been decreased by double-digit percentage already including bitcoin. Simple advice, just hold your coins that you bought already and wait for the price of the coins to increase again. That is better than selling at a cut loss because if you only hold it you don't have a loss because anytime it can rise again but if you sold it at a lower price compare to the price you buy it then that is the time that you are loss. Just hold it don't let your emotions defeat you.
