The recently revised "Digital Assets Act" (AB 1052) in California aims to protect the rights of cryptocurrency payments and self-custody, allowing residents to use digital assets like Bitcoin for transactions and prohibiting public agencies from taxing or restricting them. The bill also prohibits public officials from promoting digital assets to avoid conflicts of interest and requires exchanges to transfer long-inactive crypto assets to the state government. As the world's fifth-largest economy, California's move may set a precedent for other states in the U.S., promoting the legalization and improvement of regulatory frameworks for cryptocurrencies.
