When tech is trending up, buy TQQQ or rotate into the hottest crypto (BTC/ETH/XRP) when Bitcoin is surging; if tech is too hot, briefly hedge with UVXY. In downtrends, sit in T‑Bills (BIL) and only touch UVXY on extreme signals.

Each day: 1) If TQQQ (3x Nasdaq‑100 tech fund) is above its 200‑day average (uptrend): - If TQQQ looks “cold” (RSI, a 0–100 recent up‑vs‑down score, <30): buy TQQQ. - Else if Bitcoin’s RSI >70 (“hot”): buy the strongest of BTC/ETH/XRP. - Else if TQQQ’s RSI >80: buy UVXY (volatility spiker). - Else: hold TQQQ. 2) If not in uptrend: park in BIL (T‑Bills); only buy UVXY when SPY (S&P 500) is extremely “hot” or UVXY is very “cold”.

Out-of-sample: ~13.8%/yr with 29% max drawdown and Sharpe ~0.53 vs SPY ~18%/yr and Sharpe ~0.88. It diversifies with tech/momentum and crypto, using a disciplined risk-off hedge to complement SPY and target regime-driven upside.
