Recently, Arizona in the United States proposed a legislative motion (SB 1231) to incorporate Bitcoin into the state’s financial reserves, aiming to promote BTC as an alternative reserve asset to fiat currency. If passed, the state may become the first local government in the U.S. to include Bitcoin on its balance sheet, following the model of El Salvador but focusing more on financial reserves rather than mandatory circulation. This move reflects the exploration of financial sovereignty by conservative states, but it also faces volatility risks and conflicts with federal regulations (such as the SEC's position). Supporters believe it can hedge against dollar inflation, but practical issues such as technical custody and fair value accounting remain to be solved, which may lead to more red states following suit in the future.
