According to @MacroScope17, Bitcoin (BTC) price movement is closely tied to changes in global M2 money supply, while Ethereum (ETH) responds more directly to US Federal Reserve quantitative easing (QE) and interest rate cuts. Since 2022, the ongoing Federal Reserve quantitative tightening (QT) program has reduced market liquidity, affecting both BTC and ETH trading dynamics (source: @MacroScope17 on Twitter). Traders should monitor global liquidity trends and central bank policy shifts for strategic positioning.
