According to Cointelegraph: BlackRock's spot Bitcoin exchange-traded fund (ETF), iShares Bitcoin Trust (IBIT), has reportedly passed a watershed moment, amassing over 100,000 BTC under its management. Notably, the ETF has seen combined daily inflows break another record at $631.3 million, indicating robust investor interest in Bitcoin.

Official data from BlackRock indicates that by February 13, IBIT held 105,280 BTC. Among the nine spot Bitcoin ETFs trading, excluding Grayscale Bitcoin Trust ETF (GBTC), IBIT is the first to reach the 100,000 BTC milestone in just 22 days of trading.

BlackRock launched its spot Bitcoin ETF on January 11, 2024, alongside 10 other issuers. Since its debut, the firm has grown its iShares Bitcoin Trust's holdings substantially, from 2,621 BTC on January 11 to 100,000 BTC on February 13 - a growth of more than 3,700%.

Accumulation has been a common theme among the nine spot ETFs. For instance, the Fidelity Wise Origin Bitcoin Fund (FBTC) held 83,925 BTC as of February 13. Conversely, GBTC stands alone as the single spot Bitcoin ETF that has been actively reducing its BTC holdings since the historical spot Bitcoin ETF launch in the US – from an initial 619,220 BTC to 463,475 BTC.

As spot Bitcoin ETFs posted a record daily net inflow, with 10 spot Bitcoin ETFs recording a total of $631.3 million in a single day, BlackRock's iShares Bitcoin ETF alone drew in $493 million. Some crypto-watchers have indicated that BlackRock might be struggling to match the overwhelming demand driving the massive inflows into its Bitcoin ETF.

This news follows Bitcoin's recent rally to over $51,000, its highest value since November 2021 and its second instance of reaching a market capitalization of $1 trillion. Bitcoin is currently trading around $51,383, reflecting a 20% increase over the past 30 days. Amid this bull run, the Crypto Fear and Greed Index is hitting levels unseen since Bitcoin's all-time high of $69,000 in mid-November 2021.
