Bitcoin Exchange Reserves Drop as Asia, Europe Drive Trading Volume Shift

Bitcoin (BTC) balances held on major centralized exchanges continued to decline Thursday, alongside a sharp shift in trading activity toward Asia and Europe—signals that typically point to changing 'liquidity conditions' and repositioning by large traders.

Data from CoinGlass showed that as of May 8 at 01:55 UTC, total BTC reserves across leading exchanges stood at roughly 2,451,555 BTC. Net outflows totaled about 2,135 BTC over the past 24 hours, extending to 6,239 BTC over the last seven days. On a one-month basis, exchanges recorded net outflows of 41,941 BTC, reinforcing a steady medium-term drawdown in exchange-held supply.

Among major venues, Coinbase Pro held the largest reported balance at 851,078 BTC. The platform saw net outflows of 1,564 BTC over 24 hours and 1,555 BTC over the past week. Binance followed with 613,577 BTC in reserves, posting 1,002 BTC in daily net outflows and 2,726 BTC in weekly net outflows. Bitfinex held 404,360 BTC, logging a small daily net inflow of 15.96 BTC but a weekly net outflow of 1,887 BTC.

On the daily leaderboard, the largest net inflows were observed at Bybit (554 BTC), OKX (214 BTC), and Bithumb (72 BTC). The largest net outflows were recorded at Coinbase Pro (-1,565 BTC), Binance (-1,003 BTC), and Korbit (-208 BTC).

While exchange reserves were falling, Binance’s BTCUSDT market showed a pronounced regional rebalancing in turnover. CoinGlass data put trading volume at $575.98 million during the Asia session, $1.04 billion during the Europe session, and $135.22 million during the U.S. session. Compared with the prior day—$292.68 million (Asia), $536.88 million (Europe), and $350.29 million (U.S.)—Asia volume rose about 97% and Europe volume climbed roughly 94%, while U.S. hours volume slid around 61%.

The divergence suggests that Thursday’s price discovery and liquidity provision were driven primarily by Asian and European participants, with European-hours activity especially dominant as volumes cleared the $1 billion mark. In market terms, persistent exchange outflows are often associated with reduced readily available sell-side supply—though the metric can also reflect internal custody moves, collateral transfers, or shifting venue preferences rather than pure spot accumulation.

For now, the combination of continued reserve drawdowns and a Europe-led volume surge underscores how rapidly BTC market activity can rotate across regions, potentially amplifying volatility when liquidity concentrates in a narrower set of trading hours.
