Blockchain data analysis company ChainCatcher recently announced that Samara Cohen, chief investment officer of BlackRock ETF and index investment, revealed at the Coinbase Cryptocurrency Summit that about 80% of Bitcoin ETF purchases may come from autonomous investors, who usually configure through online brokerage accounts.

According to the 13-F filings of the previous quarter, hedge funds and brokerage firms have also become buyers, but registered investment advisors have been more cautious. Financial advisors' concerns about Bitcoin are mainly focused on cryptocurrency price volatility and its relatively short record.

Samara Cohen further pointed out that Bitcoin ETFs can serve as a bridge between cryptocurrencies and traditional finance, which is of great significance to promoting the development of the cryptocurrency market.
