A bitcoin timing switch. When bitcoin looks washed out, it buys a 2x long bitcoin ETF (BITX/BITU). When it looks overheated, it flips to a –2x short ETF (SBIT). Otherwise it parks in T‑bills (BIL). Very aggressive, swing‑trading style.

It uses IBIT (a spot bitcoin fund) as a thermometer. RSI is a 0–100 “hot/cold” meter from recent price moves: low = washed out, high = overheated. - If IBIT’s 9‑day RSI < 34: buy a 2x bitcoin fund (whichever of BITX or BITU looks more “washed out”). - Else if IBIT’s 2‑day RSI > 82: buy SBIT (–2x bitcoin). - Otherwise: sit in BIL (T‑bills).

RSI-driven crypto timing strategy switching 2x long BTC, -2x short BTC, or cash. Out-of-sample: Sharpe ~0.33; ~3.4% annualized. A differentiated, risk-managed crypto tilt to diversify the S&P 500.
