On Tuesday, BlackRock added the bitcoin ETF to its income and bond-focused funds in the first quarter. The firm’s Strategic Income Opportunities Fund (BSIIX) holds over $3.5 million worth of IBIT, while its Strategic Global Bond Fund (MAWIX) holds $485,000.
Buying activity for IBIT ramped up recently amid bullish sentiment for bitcoin and the broader crypto market. The bulls gained momentum after the listing approval for ether
That helped mark a sudden shift in IBIT, which recorded low or even zero inflows before May 15 and saw its first-ever day of outflows in April, leading to bearish sentiment.
