Google Trends
Bitcoin
Google search interest for bitcoin, beside price.
Why it matters
It measures the outside crowd — people looking it up, not trading it.
How it is built
Google Trends interest index, daily, with BTC price overlay.
What to watch
Search spikes lag price at bottoms and coincide at manic tops. Caution: the index is rescaled to 100 within its window, so 2017's and 2025's values are not directly comparable levels.
