Bybit suddenly faced a short sell-off, without a clear sudden signal. What you have to do is to hold on to the belief that it will fall, but you can't be sure when it will drop. Moreover, due to the prolonged period of wanting it to drop but not doing so, it might change your original intentions and persistence. Therefore, don't guess, don't insist, adapt to the situation, and only by controlling your position can you respond to unexpected situations.

However, since we've identified the reason for the sell-off here, the subsequent matters will be easier to handle.
