651 BTC worth $50M moved from unknown wallet to Coinbase Institutional.

A transfer of 651 BTC — valued at approximately $50.06 million — has been recorded moving from an unidentified wallet to Coinbase Institutional. The destination is notable: Coinbase Institutional typically serves large custodial and OTC clients rather than retail flow.

Moves of this size to an exchange-linked custodian can signal intent to sell, but they can equally reflect custody migration or OTC desk pre-positioning. Without further on-chain context, the direction of intent remains open. Traders watching BTC order flow will be monitoring whether corresponding sell-side pressure materialises in the near term.
