There are two emotions that we most often feel, namely fear and greed, and of course this affects our profit or loss in trading, if we are afraid to lose, usually we will actually lose more, because we don't dare to cut losses and continue to hope for movement the price will reverse direction.
Cut loss is indeed a tough decision to be taken by a trader, because the value of our assets will certainly go down. But we must have a strong prediction, if we believe the price will go down again then we have to do a Cut loss to get more profit. We can get coins at lower prices, and the number of coins we get will be bigger. Of course it will have a bigger profit potential if the price goes up again .
