Cutting your losses will create an advantage if you are trading using leverage, that is to limit your losses so you won't lose a huge amount that you can't afford losing. However, if you only trade just a small amount, I think cutting your losses is not that essential. You can trade and lose your small capital, and that's okay. You can still trade again when you're able and capable enough, as despite of your losses, you are also learning as well.
So in doing leverage trades, we can't also be able to use a small amount of capital? If it's also possible then, we can just go with the flow as well, because like you said, we can still learn a valuable lesson with it.
But some can stop doing it, if they think they are not good with it, because a small amount can still stack, and that will still result for a larger amount. Other than trading a small amount, many traders are also not doing a cut loss or a stop loss when they trade on spot. But they just choose to wait for the prices to bounce back. I think for those who are less confident or beginners on it, they can still choose to do it. Only to be safe.
