In 2025, the cryptocurrency portfolio should focus on "core assets (BTC/ETH) + diversified allocation + dynamic risk control," balancing risk and returns through a barbell strategy. Recommendations:

Conservative: BTC 50%, ETH 20%, blue-chip coins 20%, cash 10%;

Aggressive: BTC 30%, ETH 15%, high-growth altcoins 30%, meme coins 5%, US stocks/cash 20%.

Investors should regularly review and maintain flexibility to respond to market changes and black swan events.
