BlackRock Makes Massive Crypto Deposits to Coinbase

The evidence strongly supports the statement that BlackRock deposited cryptocurrency to Coinbase. The most authoritative source, a report from the Czech National Bank, explicitly states that BlackRock's iShares Bitcoin Trust (IBIT) uses Coinbase Custody as its primary method for holding bitcoin. For Coinbase to 'hold' the bitcoin, it must first be transferred to them, which is functionally a deposit. This core fact is corroborated by multiple high-relevance sources directly from Coinbase's own website. These pages repeatedly mention 'BlackRock's iShares Bitcoin Trust' in the context of 'custody' and 'custodial risk', confirming the established relationship. The act of placing an asset into the care of a custodian necessitates a transfer or deposit. The sources mentioning the scale of investment in the BlackRock ETF further imply the magnitude of these deposits. While some lower-relevance sources discuss other BlackRock funds or market news, they do not contradict the primary evidence. There is a consistent and strong body of evidence from credible sources establishing that Coinbase is the custodian for BlackRock's Bitcoin ETF, which by definition requires BlackRock to deposit its cryptocurrency assets with Coinbase.
