Bitcoin is no longer trading on crypto sentiment alone. It is now reacting to stock market fear.

A new indicator tracking this shift is now live.
The USVIX, a volatility index based on S&P 500 options, is now available on Glassnode. It measures expected market fear over the next 30 days in traditional markets.
Why this matters ?
Since the launch of spot Bitcoin ETFs, Bitcoin has become more connected to U.S. equities. Capital is now flowing through the same channels.
That changes how Bitcoin moves.
When fear rises in the stock market, liquidity tightens. Risk assets get sold. Bitcoin is now part of that group.
The chart shows this clearly.
Spikes in the USVIX are aligning with sharp moves in Bitcoin. Periods of low volatility in equities are also showing more stable price action in BTC.
This was not always the case.
Earlier, Bitcoin moved more independently, driven by crypto native factors. Now it is increasingly reacting to macro conditions.
This means one thing.
To understand Bitcoin’s next move, you also have to track traditional market risk.
The gap between crypto and traditional finance is getting smaller, and indicators like USVIX are starting to show that shift in real time.
