Remember one thing during a bear market: prioritize survival, don't think about making money.

Don't borrow money, don't leverage, as bear markets are highly volatile and it's easy to lose everything directly.
Don't buy the dip just because prices are falling; the more you buy, the more you're trapped, and once your bullets are gone, there's no chance left.
Don't hold on stubbornly without cutting losses; the deeper you get trapped, the harder it is to break even.
Don't trade frequently; hot spots in a bear market are all traps, the more you move, the more you lose.
Don't touch garbage coins or junk stocks; in a bear market, they will only keep falling all the way down.
Keep your positions light, hold more cash, and don't rush into the market.
Focus only on quality assets, wait until prices stabilize, then gradually buy in batches.
Control your hands, operate less, and avoid greed—getting through it is the victory.
