I only take one note: When the oracle feeds prices slowly and you think you can hold on a little longer, the on-chain system is actually calculating based on the "old price" and will liquidate you as soon as you're close to the margin call, so don't just watch the K-line for reassurance.

Reduce leverage, leave some margin, and don't rely on "there's still time" for risk control.
By the way, hardware wallets are out of stock lately, and phishing links are everywhere, which further proves that security is never a matter of optional choices.
Anyway, now I always double-check the domain name before signing any transaction.
