1,759 BTC worth approximately $142 million was transferred from an unknown wallet to Coinbase Institutional, signaling potential sell-side activity by a large holder. The transfer represents one of the notable whale movements observed in recent on-chain data. Coinbase Institutional deposits are typically interpreted as a precursor to selling, as they indicate funds are being moved to a custodial exchange for execution. The $142 million value places this among significant single-wallet transfers tracked by on-chain monitoring services.
