I never think that stop loss be a challenge, I just set it because I need it to manage the loss and also risks that I am probably getting while trading in the future (mostly).
And about trading in spot, I only a few times also using SL, moreover if it is a good or top coins, I will prefer to wait for increasing price. But once more, it doesn't mean that never using SL for a spot. Sometimes, it is also good to use SL because I want to manage the funds in order to ensure to lose small and then get another chance in another trading
It is great that you do not find this challenging but believe me many people do not like to use a stop loss, they feel their potential profits could go down by the use of a stop loss and in a way they are not wrong.
However trading is not only about maximizing your profits, trading is also an exercise on resource management, and since our capital is limited if we trade as if it is infinite sooner or later it will run out, a stop loss is there to protect you from this ever happening and as such it is an invaluable tool in the arsenal of any trader.
