CoinWorld news, on May 28, global asset management giant BlackRock recently adjusted some of its investment portfolios, significantly increasing the holding proportion of its spot Bitcoin ETF (IBIT). This move is seen as the latest signal of institutional investors' recognition of Bitcoin's long-term value. Since IBIT was approved for listing in January of this year, it has become one of the most popular Bitcoin ETFs, attracting over $10 billion in cumulative funds. Analysts point out that BlackRock's allocation adjustment may lead more traditional financial institutions to follow suit, further promoting the mainstreaming of Bitcoin. Currently, BlackRock has not publicly disclosed the specific scale of its increase, but market monitoring data shows that the recent inflow of funds into IBIT has continued to rise, reflecting strong institutional demand.
