$BTC data shows that in 2024, the average holdings of crypto funds include 35% Bitcoin, 28% Ethereum, 22% leading altcoins, and 15% cash equivalents. This allocation maintains a foundational position in mainstream assets while capturing excess returns through altcoins, and also reserves liquidity to respond to black swan events. Retail investors can make minor adjustments based on this, such as subdividing the altcoin position into sub-sectors like infrastructure, application layer, and metaverse, selecting 2-3 projects with technological differentiation in each sub-sector.
