You people know that I do not encourage stop loss. From my experience, I know that it is used by greedy traders.
I think bro your opinion about stop loss is different, as I think SL is not a tool for greedy traders. Instead, as others have indicated, it is the literal backbone of professional risk management. Relying solely on small position sizes to absorb downturns assumes the market will recover, but in crypto anything could happen. So I would never trust my capital to the market; instead, cutting losses is the typical and best way to stay in the market with more money that you can risk on an opportunity.
Because doing it with multiple trades at the same time could make you stuck with them for a long time, even if the liquidation price is too low. But with, let's say, 5 to 9 trades open at the same time, you won’t be able to close them before the market starts a downtrend, and being stuck there means most of your capital is locked. Although your plan might work when you are opening a single trade at a time.
