Lending and borrowing stuff has now given me a bit of a "reflex": as soon as I see the liquidation line just three steps away, I don't think about bottom fishing or not, I first cool down my positions. Usually I do three things: add some margin (but not in a reckless all-in way), conveniently reduce leverage / pay off a small portion of debt, close high-volatility positions that can be closed, keep stablecoins as a buffer, because staying alive is the most important.

If on-chain fees get too high, I become even more cautious, willing to earn less rather than get stuck in confirmation and get kicked out by the system in those few minutes.
Recently, the community has been arguing again about privacy coins, coin mixing, and the boundaries of compliance, and the debate is quite fierce. Watching this, I understand even better: rules change on a whim, liquidity can disappear just like that, and when you're near the red line, relying on "faith" is useless—only the buffer you hold in your hands can save you.
What I’ve learned isn’t a skill, but that when you’re three steps from the red line, admit you’ll panic first, then use the dumbest method to reduce that panic.
