My BTC investment portfolio adopts a "core + satellite" strategy. The core position (70%) consists of long-term held spot BTC, with dollar-cost averaging to smooth costs; the satellite position (30%) is used to enhance returns, including: 1) 5% BTC perpetual contracts (3x leverage) for trend trading; 2) 10% BTC options (mainly selling put options to earn premiums); 3) 15% DeFi staking (using WBTC to participate in AAVE lending). At the same time, 5% USDT is kept as flexible funds. The annual return target for the portfolio is 15-20%, with strict stop-loss discipline (liquidate contract positions if losses exceed 15%) and regular rebalancing (adjust once a month) to control risk.
