As for borrowing and lending, when the liquidation line is only "three steps" away from me, my current update is: don't force it for now.

Step one: reduce my position to a level I can sleep through tonight, even if it means earning less;
Step two: pay back a part of the borrowed amount first, don't expect a rebound to save me;
Step three: set a very ugly but effective stop-loss / margin call reminder, don't wait until you're panicking.

Recently, the group has been discussing stablecoin regulation, reserve audits, and various rumors of "de-pegging," the more they talk, the calmer I become...
Honestly, emotions are the easiest to push people to the red line.
Anyway, my current strategy is: don't follow the trend and increase leverage, keep some cash on hand, and move myself further away from the red line first.
