Hundreds of millions of dollars flowed yesterday into the U.S. Bitcoin ETFs. Are the BTC funds from BlackRock and other providers ushering in the bull market?

Last week, the ten U.S. Bitcoin Spot ETFs already convinced with more than a billion U.S. dollars in net inflows. According to new data from Farside Investors, they underscored this bullish sentiment at the beginning of the week. On Monday, US$300.9 million was already flowing into the BTC index funds, and yesterday they raised an impressive US$422.5 million. This is the best daily result for Bitcoin ETFs since June 5.

Meanwhile, Bitcoin stands at €59.289, which is up 1% from yesterday. In fact, compared to the previous week, Bitcoin is up 10.97 percent. The highest net inflows were recorded yesterday by market leader BlackRock, whose iShares Bitcoin Trust pulled in $260 million. According to the Apollo Bitcoin Tracker the BlackRock ETF currently owns 322,123 BTC.

This puts BlackRock ahead of the competition and, more importantly, increases its distance from the number two, Grayscale, whose Bitcoin ETF is slowly deflating. Since the ETF launched on Jan. 11, the GBTC has lost more than 345,000 BTC.

But the ARK 21Shares Bitcoin ETF also shone over the past two days with net inflows of US$147 million. The fourth-largest BTC index fund from Cathie Wood's investment firm holds more than 50,069 Bitcoin.

Collectively, the U.S. Bitcoin ETFs now hold 891,000 BTC, representing about 4.52 percent of the total circulating BTC volume. BlackRock alone controls an impressive 1.63 percent of all currently existing Bitcoin. The U.S. financial giant's market share continues to grow steadily.
