Basically trading is very risky because the nature of the market is very volatile and anyone will not be able to predict with 100% accuracy, even those who are experienced still have difficulty. Losses will always be there, and I am sure you will not want to continue to experience losses, well so the only way to reduce the amount of loss is to learn a lot about something that can make you lose and avoid it. So you will be able to get profits consistently but with a lower level of loss because you always learn to be better.
Market may be volatile but the frequency are I think can also depend on the coin that we choose. As you said, losses are always there, therefore don't say that we can avoid it. The first one that you said which is to reduce the loss is already okay.
Yes, no one wants to lose continuously, that sucks. I'd rather donate my money to the charity than lose it for nothing. I know, we can gain an experience but it's useless if we are not improving. In trading, consistent profits for a long period of time is not possible but it's fine, as our losses in some days can still be compensated by our profitable days. Traders who are like this are already pro or skillful but if they can learn more and improve more, why not?
even making our win more than our losses is such a feat in trading sometime it really requires adequacy and proficiency in both resources and skills in observing the market.
but the fact that the market always dynamically change, basically can't be too fixated on a certain book about knowledge in trading mean that our win and lose rate would be inconsistent as well so really can't be sure whether our win will be more than our losses.
honestly this is one thing that make me devoted investors instead of trader, because it just make sense, wait it out, and it will rise.
with trading not so much, you can be trapped in a bearish, losing 80% of your traded capital, and make decision whether to become "investor" or just cut loss.
