The core of the long-term holding strategy for $BTC lies in selecting tokens with strong fundamentals, technical advantages, and ecological support, while maintaining sensitivity to market cycles and macro trends. Bitcoin and Ethereum, due to their decentralized characteristics and market positions, remain the preferred choices for HODL; emerging tokens need to be cautiously evaluated for their long-term potential. Profit-taking should be based on target returns, market cycles, and fundamental changes, using a staggered selling approach to balance returns and risks. Musk's 'American Party' may bring new political and emotional catalysts to the crypto market, and long-term holders should pay attention to its policy trends, but always keep project fundamentals as the core of their decision-making.
