Bitcoin Held on Major Exchanges Tops 30-Day Average as Net Flows Swing to Outflows

Bitcoin holdings on major cryptocurrency exchanges have moved above a short-term baseline, but actual net flows have turned toward withdrawals, according to an analysis. The increase in headline exchange balances alone does not necessarily mean selling pressure has strengthened.

CryptoQuant Quicktake contributor CrazyBlock wrote on June 8 that Bitcoin exchange reserves moved back above their 30-day moving average on May 11. The shift indicates that a stretch in which exchange balances had remained below trend has ended.

As of June 8, total Bitcoin held across exchanges stood at about 2.72 million BTC. That was about 62,600 BTC above this cycle's low recorded on April 25, an increase of roughly 2.36%.

On the surface, the data suggest Bitcoin supply is flowing back to exchanges. Historically, rising exchange reserves have often been interpreted as a sign of potential selling pressure.

Recent net flows, however, point the other way. The adjusted seven-day average net flow turned sharply negative over the past week, according to CrazyBlock. The prior seven-day average was about positive 224 BTC a day, or close to neutral, but recently fell to negative 3,958 BTC a day.

That means daily withdrawal pressure expanded by more than 4,100 BTC over a short period. While exchange reserves remain above the 30-day average, actual fund flows have shifted toward leaving exchanges.

Market conditions have also changed. After 26 consecutive days in a mild inflow phase, the Bitcoin market returned to a neutral zone on June 8, CrazyBlock wrote. In past cycles, similar setups have appeared ahead of meaningful supply contraction.

Exchange reserves are still about 6% below the roughly 2.9 million BTC peak reached in September 2025. That suggests the structural absorption of exchange supply has not fully run its course.

CrazyBlock said that when assessing Bitcoin's market structure, the direction and speed of actual net flows matter more than the absolute level of exchange reserves. With exchange holdings rising even as net flows turn negative, investors need to monitor both short-term selling pressure and the longer-term trend of supply absorption.
