Always interesting to see this kind of movement, but honestly, people need to stop tracking every whale transaction like it's a guaranteed dump. 840 BTC is a decent chunk, but Coinbase Institutional is usually where guys go to park coins for OTC desks or custody, not necessarily to smash the market. I’ve backtested these "whale alert" signals against price action for years and the correlation to immediate downside is pretty much non-existent. Probably just some institution rebalancing their cold storage. Wouldn't read too much into it unless we see a massive spike in exchange inflows across the board.
