Etfs ETF Balance 2 ETF Balance 2
Bitcoin
This measures the Bitcoin ETFs' holdings as a share (dominance) of total Bitcoin supply.
Why it matters
It shows how much of the circulating supply is locked inside regulated ETF vehicles.
How it is built
Total ETF-held BTC is divided by circulating supply.
What to watch
A rising share reflects supply migrating into long-term institutional custody, tightening free float.
