I also have same problem with you, but i still hold it. stop or not it's depend on your money/budget, if you can hold for long time so it's recomended to hold but if you really need money so you don't have other option except sell your coin.
If you are person with low patience it's recomended not to trade because you can not control your emotion. If you still want to trade, trade with money that you can afford to lose
A trader must have a strong command over emotions and should have huge patience to enjoy the great profit. Many traders go in loss because they panic when the prices are low and provide chance to others for enjoying the profit.
Emotions have significant effect on your decision making. Trading is a business where we need to use only our brains than hearts. A good understanding of crypto market, its trends and sound knowledge of coping emotions are criteria to be a good trader.
