Bitcoin is exiting exchanges, but why are ETFs still buying?

Bitcoin’s declining exchange balances indicate that investors are moving coins into private custody, reducing immediately available supply and potentially signaling long-term accumulation. At the same time, spot Bitcoin ETFs continue buying, creating sustained institutional demand even as exchange liquidity tightens. The divergence likely reflects different investor channels rather than conflicting signals: retail and long-term holders are withdrawing coins while institutions gain exposure through ETFs. If the trend persists, reduced liquid supply could amplify Bitcoin’s price sensitivity to new demand.
