Investors are flocking to BlackRock's (NYSE:) spot Bitcoin ETF in droves, pushing its single-day trading volume to nearly $3 billion, an analysis by The Defiant has revealed.

The world’s largest asset manager launched its iShares Bitcoin Trust (NYSE:) ETF earlier this year to provide U.S. investors with a convenient and easily accessible route for investing in the world’s leading cryptocurrency.

Since the ETF's launch, BlackRock has been diligently purchasing over $100 million worth of Bitcoin on a daily basis.

The broader market for Bitcoin ETFs has witnessed substantial growth, with AUM reaching $131.08 billion, highlighting the accelerated institutional adoption of cryptocurrencies globally. In the past month alone, Bitcoin ETFs have pulled in $6.5 billion in AUM.
