Introduction | 引言

Risk management is the single most important factor that separates successful cryptocurrency traders from those who lose everything. In the highly volatile crypto markets, where 20-50% drawdowns are common, having a robust risk management framework is not optional — it is essential for survival and long-term profitability.

风险管理是区分成功加密货币交易者和爆仓者的最重要因素。在波动性极高的加密市场中，20-50%的回撤是常态，拥有稳健的风险管理框架不是可选项，而是生存和长期盈利的必需品。

Position Sizing: The Kelly Criterion Approach | 仓位管理：凯利公式

The Kelly Criterion provides a mathematical framework for determining optimal position sizes. In crypto trading, a conservative fractional Kelly approach (25-50% of the full Kelly) is recommended due to the extreme volatility. Never risk more than 1-2% of your total portfolio on any single trade. This means if your total capital is $10,000, your maximum risk per trade should be $100-200.

凯利公式提供了确定最佳仓位大小的数学框架。在加密交易中，由于极端波动性，建议采用保守的部分凯利方法（全凯利的25-50%）。在任何单笔交易中，切勿冒着超过总投资组合1-2%的风险。这意味着如果你的总资金是1万美元，每笔交易的最大风险应为100-200美元。

Stop-Loss Strategies for Crypto | 加密货币止损策略

Stop-losses are your first line of defense. There are several proven approaches: 1) Volatility-based stops using ATR (Average True Range) — set stops at 1.5-2x ATR below entry. 2) Support/resistance stops — place stops just below key support levels. 3) Time-based stops — if a trade hasn't moved in your direction within a set timeframe, exit. In crypto, trailing stops are particularly effective during strong trending markets.

止损是你的第一道防线。有几种经过验证的方法：1) 基于波动率的止损，使用ATR（平均真实范围）——在入场价下方1.5-2倍ATR处设止损。2) 支撑/阻力止损——在关键支撑位下方设止损。3) 时间止损——如果交易在设定时间内没有朝你的方向移动，就退出。在加密市场中，移动止损在强趋势市场中特别有效。

Portfolio Diversification in Crypto | 加密投资组合分散化

Diversification in crypto extends beyond just holding different coins. A comprehensive approach includes: allocating across market cap segments (large-cap blue chips, mid-cap growth, small-cap high-risk), diversifying by sector (L1s, L2s, DeFi, gaming, AI tokens), and incorporating uncorrelated assets like stablecoin yields. Rebalance quarterly to maintain target allocations.

加密投资组合的分散化不仅仅是持有不同的币种。一个全面的方法包括：按市值分配（大盘蓝筹、中盘成长、小盘高风险），按赛道分散（L1、L2、DeFi、游戏、AI代币），并纳入稳定币收益等低相关资产。每季度重新平衡以维持目标配置。

Risk-Adjusted Returns: Sharpe and Sortino Ratios | 风险调整回报：夏普比率与索提诺比率

Don't just look at raw returns. The Sharpe Ratio measures return per unit of total risk, while the Sortino Ratio only considers downside risk — which is more relevant for crypto. A Sharpe ratio above 1 is considered good; above 2 is excellent. In crypto, focus on the Sortino Ratio as it penalizes only the losses that matter. Use these metrics to evaluate your trading strategy objectively.

不要只看原始回报。夏普比率衡量每单位总风险的回报，而索提诺比率只考虑下行风险——这对加密市场更相关。夏普比率超过1被认为是好的，超过2是优秀的。在加密领域，重点关注索提诺比率，因为它只惩罚重要的亏损。用这些指标客观评估你的交易策略。
