Vetle Lundle, senior analyst at 33 Research, said the indirect increase in bitcoin investments by Norway's sovereign wealth fund, the world's largest, which is currently worth more than $144 million, may not have been intentional, and if it was intentional to expose the fund to more bitcoin, the move perfectly illustrates how bitcoin is maturing as an asset and is integrated into any diversified portfolio. Indirect investments come from increasing investments in companies that hold bitcoin. For example, the fund adjusted its holdings of MicroStrategy shares to 0.89% of its total portfolio. In addition, the fund also increased its stakes in Coinbase and Block Inc (formerly Square), and started investing in mining company Marathon Digital.
