Stablecoins are bound to be the most important and far-reaching financial innovation of the next 10 years. The United States has already seen three states—Arizona, New Hampshire, and Texas—pass the 'Bitcoin Reserve Act.' The U.S. Senate GENIUS has passed the stablecoin bill, and in terms of legal compliance, from May 19, 2021, when they were mainly seen as a threat, to May 19, 2025, stablecoins have become an important tool for foreign trade settlements. BTC has become a reserve in some U.S. states, transitioning from being overlooked to entering the mainstream market. Financial inclusion seems like a long journey, but in reality, it has only been 4 years; the world has changed dramatically.
