Choose your depth. The data doesn't change — just the explanation.
When the government prints more money, some of it eventually flows into Bitcoin — with about a 3-month delay. Watching the money supply gives you a heads-up that most people don't have.
FRED tracks M2 money supply monthly. When M2 YoY growth turns positive, Bitcoin has rallied within 90 days in 8 of 10 historical instances. The signal is strongest at market bottoms — M2 must recover before crypto prices follow. At tops, smart money exits before M2 peaks.
r=0.72 over 2020–2024 (one full cycle — short sample). Signal breaks during idiosyncratic shocks (Terra/Luna 2022, SVB 2023). M2 data has 2-week publication lag. The asymmetry (BTC leads at tops, M2 leads at bottoms) is mechanistically plausible: liquidity flows require money supply to recover before speculative assets reflate.

Indicator Comparison
M2 outperforms Fed Funds Rate and CPI as a directional Bitcoin predictor. The 90-day lag is optimal — shorter lags lose signal, longer lags become coincident.

🔄 The Key Asymmetry
BTC leads M2 at tops. Smart money exits Bitcoin before M2 peaks. M2 leads BTC at bottoms. Liquidity must recover before speculative assets can reflate. This asymmetry means M2 is most useful as a buy signal, not a sell signal.
