Institutional investors have rapidly increased their exposure to Bitcoin, accumulating a significant portion of the cryptocurrency's total supply. According to a recent report from K33, institutional investors acquired a total of 859,454 BTC by 2024, representing approximately 3% of the total Bitcoin supply. This surge in institutional adoption is largely attributed to the growing recognition of Bitcoin as a legitimate asset class. The launch of Bitcoin spot exchange-traded funds (ETFs) has played a critical role in attracting institutional capital to the cryptocurrency market. Currently, Bitcoin spot ETFs have 1.4 million BTC under management. Key institutional players, such as BlackRock, have also made significant investments in Bitcoin. BlackRock's iShares Blockchain and Tech ETF (IBIT) recorded net inflows of $36.7 billion during 239 trading days, surpassing the record set by its gold ETF. Furthermore, the combined assets under management for US Bitcoin spot and derivatives ETFs recently surpassed that of gold funds for the first time on August 16. This milestone underscores the growing institutional interest in Bitcoin over traditional safe-haven assets.
