Bitcoin Exchange Reserves Decline as US Trading Volume Surges

Bitcoin (BTC) is seeing a renewed drawdown in exchange-held supply, with major centralized venues posting net outflows across daily, weekly, and monthly windows. The move suggests a continued shift toward self-custody or longer-term holding behavior, even as trading activity accelerated sharply—especially during U.S. hours—highlighting a market that is simultaneously removing coins from exchanges while actively repositioning.

As of Sunday, July 26 at 4:30 a.m. ET (8:30 a.m. UTC), CoinGlass data showed total BTC reserves across major exchanges at roughly 2,481,594 BTC. Over the past 24 hours, exchanges recorded a net outflow of about 4,637 BTC. The seven-day tally also remained negative at roughly 4,624 BTC in net outflows, while the 30-day figure showed a smaller but still net decline of about 598 BTC.

Among individual venues, Coinbase Pro held the largest reported balance at approximately 850,356 BTC. It posted a daily net outflow of around 231.62 BTC and a weekly net outflow of about 2,024.74 BTC. Binance followed with roughly 647,167 BTC in reserves, alongside daily net outflows of about 127.01 BTC and weekly net outflows of around 2,426.67 BTC.

Bitfinex ranked third by reserves at roughly 416,734 BTC. Unlike most peers, it saw a small daily net inflow of about 8.88 BTC, but still registered a weekly net outflow of roughly 183.68 BTC—underscoring that the broader weekly trend remains skewed toward net withdrawals.

On a 24-hour basis, the largest net inflows were reported at Kraken (about 91 BTC), bitFlyer (about 16 BTC), and Bithumb (about 14 BTC). The biggest daily net outflows were concentrated at OKX (around -4,120 BTC), followed by Coinbase Pro (around -232 BTC) and Bybit (around -215 BTC). The pronounced OKX figure dominated the day’s exchange flow picture and materially contributed to the overall net outflow across venues.

At the same time, Binance’s BTCUSDT spot trading activity rose across all major time zones, with the most dramatic increase occurring during U.S. hours. CoinGlass data pegged Asia-session volume at about $92.98 million, Europe-session volume at roughly $237.27 million, and U.S.-session volume at approximately $433.60 million. Compared with the prior day—about $72.85 million in Asia, $125.90 million in Europe, and $63.85 million in the U.S.—Asia rose around 28%, Europe increased about 88%, and U.S. hours surged roughly 579%.

The regional breakdown indicates the U.S. session led overall activity, followed by Europe and then Asia. That divergence—heavy U.S.-hour turnover alongside net exchange outflows—can reflect a market where liquidity demand is rising even as participants reduce exchange balances, a combination often associated with heightened positioning around macro catalysts, derivatives hedging, or a push toward off-exchange custody.

While exchange flow data does not, on its own, determine near-term price direction, sustained net outflows typically tighten readily available exchange supply. If elevated U.S.-hour activity persists, it could keep volatility and 'liquidity turnover' high even as coins migrate away from centralized venues—an important dynamic for traders monitoring the balance between available supply and demand intensity.
