An unknown wallet dumped 994 Bitcoin—$76.5 million—directly to Coinbase, joining a wave of massive exchange inflows that rippled across the industry in a single 24-hour window.

Coinbase Institutional absorbed the heaviest flow: 978 BTC ($62.8 million) and 817 BTC ($52.5 million) arrived from separate unknown wallets, alongside another 982 BTC ($75 million). OKEX took in 2,398 BTC ($153.7 million) followed by a separate 843 BTC ($53.6 million) deposit. Binance recorded a 900 BTC ($57.9 million) inflow.

The inflow narrative flipped when examining outflows. OKEX moved 1,326 BTC ($85.4 million) to an unknown wallet. Coinbase Institutional sent 959 BTC ($61.7 million) out. Coinbase itself saw two major exits: 1,657 BTC to an unknown address and 647 BTC ($51.5 million) from its institutional arm. A 999 BTC ($79.9 million) transfer moved from Coinbase to Binance.

FalconX showed classic OTC desk fingerprints: an unknown wallet deposited 954 BTC ($61.4 million), which FalconX immediately transferred out ($61.4 million) moments later—textbook rebalancing or client execution.

Stablecoin flows reinforced the picture. USDC Treasury minted 250 million USDC ($250.2 million), then 184 million USDC moved from Aave to an unknown whale and cycled back within hours—a pattern consistent with large traders preparing dry powder or hedging positions.

Bitcoin trades at $77,159, down 2.1 percent over 24 hours. The Crypto Fear & Greed Index sits at 69—greed territory—despite the price dip.

The math here matters: aggregate Bitcoin inflows to exchanges now dwarf outflows, a tell that distribution is outpacing accumulation. When whales send this much size to order books simultaneously, volatility historically follows. Watch whether these coins actually hit the bid or get held as tactical positioning for a move lower.
