BlackRock's aggressive accumulation of assets under management (AuM) in its Bitcoin ETF has been highlighted as remarkable. Concurrently, a significant outflow of Bitcoin from Coinbase was observed, with over 18,000 Bitcoin, nearly amounting to an almost $1B outflow, being withdrawn, marking one of the largest outflows recorded. The balances in the new wallets range significantly, indicating a broad distribution of the withdrawn funds. Additionally, Coinbase's recent shareholder letter revealed that the company now holds more than $100B in AuM, positioning itself as a major custodian, especially for Bitcoin ETF holdings, which it nearly monopolizes. BlackRock's latest ETF advertisement encourages investment in Bitcoin, emphasizing the opportunity for progress.
