According to Cas Abbé, a balanced crypto portfolio strategy involves allocating 40% to BTC and ETH (as foundational assets), 30% to large-cap altcoins such as SOL, AVAX, and LINK, 20% to narrative-driven mid-cap assets like AI and RWA tokens, and 10% to meme coins, but only during confirmed mania phases. Cas Abbé emphasizes adjusting allocations based on liquidity signals rather than emotions, providing traders with a data-driven framework for portfolio management. This approach helps manage risk and capitalize on trending sectors in the crypto market, with a clear focus on market liquidity as a key trading signal (Source: Cas Abbé).
