Accounting rule changes have transformed Bitcoin from a risky asset to a corporate essential, with 70 publicly traded companies, including Tesla and Block, now holding Bitcoin. This shift, driven by the FASB's ASU 2023-08 allowing market value accounting, could lead to a surge in corporate demand, potentially driving prices higher as firms seek to hedge against dollar depreciation and signal innovation. Matthew Hougan of Bitwise predicts that the number of companies investing in Bitcoin could grow to hundreds or thousands in the next 12 to 18 months.
