Some regions in the United States are piloting tax-free Bitcoin consumption policies, reflecting deep changes in the traditional financial system. When mainstream economies begin to recognize the payment attributes of crypto assets and offer tax incentives, it undoubtedly undermines the absolute monopoly of the US dollar as the sole settlement medium. This signal is very significant—moving from resistance to pilot programs in just a few years. Many analysts believe this indicates that US dollar sovereignty is loosening, and the era of diversified asset allocation has truly arrived. Once such pilot policies expand in scope, they will profoundly change retail payment habits and asset flows.
