sometimes I also experience the same thing, when the cut loss prices go back up, but I apply 10% to the cutloss, and according to my experience it's better to lose 10% and it will be easy to recover, than I did not cutloss and lose more than 50%.
I don't ever hold trades long enough to lose 50%. I only trade good, well established coins and try to trade them off within a couple of days. So, unless something major happens with the project, I don't ever see that much of a crash. How long are you trading where you see those kinds of losses? That's one of the reasons I don't hold long term. Those 50% losses would stress me out too much.
For me, it is not good to cut loss because we know crypto never remains the same in life and if you realize that the market is down its not good to risk your losing 10 percent Bette keep holding. As I know crypto is about price change so no need to be a worry at all just believes in your abilities and keep trading but at fall try to keep holding.
