**News Flash: BlackRock Amends Bitcoin ETF Amid Investor Concerns**

BlackRock, the world’s largest asset manager, has filed an amendment for its Bitcoin ETF, addressing investor worries about Coinbase’s onchain settlement practices. According to a Sept. 16 SEC filing, BlackRock now requires Bitcoin withdrawals from Coinbase within 12 hours of a client's request.

This move comes after investors raised concerns that Coinbase might be buying "paper BTC" for ETFs, potentially affecting Bitcoin prices. Coinbase CEO Brian Armstrong reassured that all ETF transactions are settled onchain, despite not sharing all ETF addresses publicly.

Analysts, however, argue that Bitcoin’s price slump is due to native holders, not ETFs.
