**Portfolio Investment: Rely on Allocation, Not Luck**

1️⃣ **Cross-Chain Diversification**: BTC/ETH as the base (60%) + Major Coins (30%) + Small Positions for Speculation (10%), to resist single-point crashes

2️⃣ **Cyclical Hedging**: Allocate Stablecoins for Yield (such as USDC) to protect the portfolio, bear market ammunition supply

3️⃣ **Dynamic Rebalancing**: Quarterly adjustment of positions, taking profits from surging coins and shifting to undervalued assets

4️⃣ **Reject ALL IN**: Any single coin ≤20% of principal, to prevent total loss risk
