4. Bitcoin Storage Security Guide

1. Exchange Storage vs. Personal Wallet

   Short-term trading: Bitcoin can be temporarily stored in the OKX account, with the platform using cold wallets to isolate 98% of assets.
   Long-term holding: It is recommended to transfer to a hardware wallet (such as Ledger, Trezor) to completely isolate from online attacks.

2. Core Principles of Private Key Management

   Private keys and mnemonic phrases must be backed up offline, and screenshots or online transmission are prohibited;
   Use metal mnemonic boards that are fireproof and corrosion-resistant, and store them in secure locations.

3. Essential Knowledge System for Cryptocurrency Beginners

4. Basic Concepts

   Blockchain: Decentralized ledger technology that ensures transactions are immutable;
   Mainstream cryptocurrencies: BTC (store of value), ETH (smart contract platform), USDT (stablecoin pegged to the US dollar).

5. Risk Control Strategies

   Do not invest more than 5% of total assets for the first time;
   Use "stop-loss orders" for automatic liquidation to avoid daily losses exceeding 10%.

6. Learning Resources

   OKX Academy: Offers free courses on blockchain technology and candlestick analysis;
   CoinMarketCap: Real-time query of market capitalization, circulation, and other key data.

7. Compliance Considerations in China

According to the "Announcement on Preventing Risks of Token Issuance Financing" by the People's Bank of China and other seven ministries:

Holding and trading Bitcoin is legal for individuals, but risks must be borne by themselves;
Financial institutions are prohibited from conducting token exchange businesses, and C2C trading is the only compliant deposit channel.
