I see some Global M2 doubters/haters. It's good to question everything, but if you don't like the M2 correlation to BTC, then just look at the gold chart.
The gold chart corroborates the Global M2 chart. They move in tandem.
▶️ Gold predicts the same move for BTC. ◀️
Gold leads BTC just like global M2 leads BTC.
