#保持SAFU SAFU (Safety First) is the survival rule for traders:

Capital Isolation: Use only idle funds, refuse to borrow leverage;

Position Control: Individual risk <2%, total position matches volatility;

Disaster Recovery Plan: Reserve 'escape funds' to respond to extreme market conditions;

Technical Moat: Use cold wallets/multi-signature to ensure asset safety.

The essence is to respect the market: no matter how sophisticated the strategy, redundancy design is necessary, survival > excessive profit.
