420 BTC Moved to Coinbase Institutional — Watch for Potential Selling

I see a large transfer of 420 BTC (~$51.86M) from an unknown wallet to Coinbase Institutional. Movement to an exchange custody account often precedes selling but can also be a custody or OTC deposit for an institutional client.

Given the size, this increases the risk of near-term selling pressure if the coins hit the order book, but the transfer alone is not definitive. I will watch for follow-through on-chain flows, orderbook changes, and price action before assuming bearish intent.
