Daily crypto momentum: 90% follows a Bitcoin trend filter; if BTC is strong, own the past‑week winner among major coins (or USDC). If BTC is weak, hold USDC. Keep 10% in cash; rebalance daily.

- Each day, check if Bitcoin is above its 20‑day average (a simple uptrend test). - If yes, buy the single best performer over the last 7 days from: BTC, ETH, SOL, LINK, DOGE, YFI, or USDC (a dollar‑pegged coin). If all fell, USDC may win. - If no, hold USDC. - 90% follows these rules; 10% stays in cash.

Crypto momentum sleeve using BTC regime filter and 10% cash. Capitalizes on top crypto leaders in up markets and parks in USDC on weakness, adding diversification versus the S&P. Note: out-of-sample risk is material; use as a tactical sleeve.
