Below are some key shares:

1. **Mastering Basic Operations:**

* **Order Types:** Proficient use of **Limit Orders** (executing at specified prices to avoid slippage), **Market Orders** (executing immediately at the best price, suitable for quick in-and-out), and **Stop-Loss/Take-Profit Orders** (automatically closing positions to lock in losses or profits, **core of risk management!**).

* **Exchange Selection:** Choose centralized exchanges (CEX) or decentralized exchanges (DEX) with good reputation, high liquidity, strong security, and transparent fees. Understand their interface, API (suitable for automated trading), and deposit/withdrawal rules.

* **Wallet Management:** Distinguish between **Hot Wallets** (online, convenient for trading) and **Cold Wallets** (offline, secure storage for large assets). Keep private keys/recovery phrases **absolutely confidential**, and enable multi-factor authentication (2FA).

2. **Core Strategic Ideas:**

* **Trend Following:** “Go with the trend.” Use tools like Moving Averages (MA), trend lines, MACD, etc., to identify and follow the main market direction. Look for pullback buying opportunities in an uptrend and short-sell or wait in a downtrend when prices are high.

* **Range Trading:** Buy at the support level and sell at the resistance level within a relatively stable price range. Requires patience to wait for prices to reach the boundaries.

* **Swing Trading:** Capture medium-term (from days to weeks) price fluctuations. Look for entry and exit opportunities based on fundamental news, technical breakthroughs, and changes in trading volume.

* **Arbitrage:** Profit from slight price differences between different exchanges or trading pairs. Requires fast execution, low fees, and opportunities that are fleeting.
