Trading can be very profitable, but it can also be quite frustrating. My advice is, don't always chase losses to get your investment back, because in that condition, you will actually lose more and get frustrated. just stop for a moment, think carefully and change strategies
In any case, it is better to under-earn a profit than to close a trade with a loss. Therefore, you should not try to sell the coin on high, because in practice, only a few manage to do this. Similarly, you will not be able to buy coins at the lowest price. And this should not upset you.
