BlackRock has adjusted its agreement with Coinbase, requiring Bitcoin withdrawals for its Bitcoin ETF to be settled on a public blockchain address within 12 hours.
The crypto community expressed doubts about Coinbase’s transparency, especially regarding their synthetic Bitcoin product, cbBTC.
Concerns arose about cbBTC being a 'paper version' of Bitcoin, raising fears of price manipulation and lack of true Bitcoin backing.
Coinbase CEO Brian Armstrong addressed the concerns, stating that all transactions are settled on-chain and that cbBTC involves trusting a centralized custodian.
