I saw those copying traders who suffered a lot of losses

They are indeed very shameless

They directly lock the copied funds, and when they lose money, they can't run away even if they want to. Everyone must pay attention to avoiding such traders

I think Binance didn't introduce this feature just to let these shameless copying traders exploit others

From the exchange's perspective, they don't want you to lose money; they are only afraid you might stop trading because most of the exchange's revenue comes from transaction fees. If you earn more and keep trading, that's what they really want.
