I have already reduced my altcoin holdings to 20%, and I'm keeping the rest in BTC and ETH, because the task force is only debating so far — no new laws have been passed yet, they are only talking about clearer rules for staking, DeFi and custody. For a pension portfolio, I recommend diversifying: 40% BTC, 30% ETH, 20% stablecoins (USDC with a reliable yield), 10% cash.
