Japanese companies that hold significant amounts of Bitcoin as part of their treasury strategies are consistently outperforming their peers in the United States. This trend can be attributed, in part, to the favorable tax policies in Japan, which facilitate and encourage investment in cryptocurrencies. As a result, it has become relatively easier for these Japanese firms to achieve better performance with their Bitcoin holdings compared to their counterparts in the U.S., where regulatory and tax challenges may pose obstacles to similar success.
