In case one faces a loss streak, and there is a need to handle bad emotions that force them to give up trading and leave the market, it is recommended to look at things soberly, turning on analytical thinking. Analyzing mistakes is one of those "pills" that can help to understand that the market is operated by regularities. It means that there is always a chance to conduct analysis correctly, even though it requires a bit more time than usual before opening the position. The prudent approach to analysis includes not only an analysis of made mistakes but also a review of successful deals because they have led to success.
There isn't really any reason to feel terrible after a loss, the best way to control your emotions would be realizing that you are not doing anything that's different than others, you are doing exactly what you could be doing, which is losing.
The crypto market, just like any other market, can't give you full profits, there is no possible way that people would have 100% trade prediction rate, you need to realize that everyone loses money. When you do realize that, you will realize that whatever amount you lost, that's fine, and you should move on. This doesn't matter do not learn from it and ignore it, it means that check your mistake, see where you did wrong and you will be able to do better in the end after a while.
