One, Basic understanding and risk warnings

1. Market characteristics

- High volatility: 24-hour trading, price fluctuations often exceed 10%, leverage contracts can amplify risk by hundreds of times.

- Information asymmetry: Frequent black swan events such as market manipulation, fake news, and project failures.

- Regulatory uncertainty: Significant policy differences across countries may lead to risks such as exchange closures and asset freezes at any time.

2. Participation principles

- Invest only with spare cash: Recommended not to exceed 10% of personal liquid assets.

- Reject FOMO: Do not blindly chase rising prices or panic sell.

- Diversified investment: Avoid investing all in a single cryptocurrency.

Two, Classification of mainstream profit strategies

1. Spot trading (low risk)

- Long-term holding

- Applicable cryptocurrencies: Mainstream coins like BTC, ETH.

- Strategy: Regular investment (e.g., buying a fixed amount weekly/monthly), ignoring short-term fluctuations, target period 3-5 years.

- Tools: Regular investment features from exchanges (such as Binance's 'Investment Plan').

- Swing trading

- Strategy: Use technical analysis (MACD, RSI, Bollinger Bands) to capture weekly/monthly trends.

- Key point: Set stop-loss (e.g., exit if falling below support by 5%-10%).

2. Contract leverage

- Long and short: Can both go long on price increases and short on price decreases.

- Strategy examples:

- Grid trading: Set price ranges for automatic low buying and high selling (e.g., Binance's 'Grid Bot').

- Breakout trading: Enter positions after key resistance/support levels are breached.

- Risk control:

- Leverage should be ≤5 times to avoid liquidation.

- Prefer perpetual contracts in U-based margin to reduce liquidation risk.

3. Arbitrage strategies

- Exchange price difference arbitrage: Buy low and sell high when there is a price difference for the same cryptocurrency on different exchanges (requires quick execution).

- Futures-spot arbitrage: When futures prices are significantly higher than spot prices, short the futures and buy spot to lock in profits.

- Cross-chain arbitrage: Profit from liquidity differences between different public chain ecosystems (requires familiarity with DeFi protocols).

Three, Sentiment indicators

- Fear and greed index: Assess whether the market is overheated or oversold.

- Social media sentiment: Discussions on Twitter and Telegram regarding popular projects.

Four, Risk control and capital management

1. Position allocation

- Mainstream coins (BTC/ETH): 50%-70%.

- Potential altcoins: 20%-30%.

- High-risk contracts/U-based margin: ≤10%.

2. Stop-loss rules

- Spot: Mandatory stop-loss when a single cryptocurrency loses over 15%.

- Contracts: Set 'trigger price' + 'execution price' as dual insurance to avoid liquidation.

3. Black swan responses

- Retain 10%-20% in stablecoins to respond to extreme price drops for bottom fishing.

- Reduce leverage or liquidate positions before significant policy announcements (such as Federal Reserve interest rate hikes).

Five, Pitfall avoidance guide

1. Reject 'shitcoins': Altcoins ranked outside the top 100 by market cap with no real application are 99% likely to go to zero.

2. Beware of pig-butchering scams: Communities claiming to be 'signal teachers' or offering 'guaranteed returns' are mostly scams.

3. Cold wallet storage: Store large assets in hardware wallets to avoid exchange failure risks.

4. Tax compliance: Retain transaction records; some countries require reporting cryptocurrency capital gains tax.
