Arkham data shows the transfers were worth about $18.97 million in ETH and $50.08 million in BTC, indicating fresh movement from the crypto asset manager to its prime brokerage venue.
Grayscale moved 11,421 ETH and 814.341 BTC to Coinbase Prime over the past 15 minutes on July 2, according to Arkham. The transfers were valued at about $18.97 million for Ether and $50.08 million for Bitcoin. Large deposits to Coinbase Prime, a prime brokerage and institutional trading platform, are often watched by traders because they can precede custody shifts, rebalancing or potential selling activity, though the transfers alone do not confirm intent.
