Bitcoin enthusiasts in California are attempting to make their state the first to recognize cryptocurrency as legal tender A state legislator in California has introduced legislation that would make bitcoin legal money in the state. The action would be in violation of the US Constitution, which provides that Congress has the exclusive authority to declare what is and isn't legal money. According to the Constitution, however, state officials are responsible for defining "legal tender."
I think that's good news for the California Bitcoin users, but as the author said it might violate the US constitution, well that's an interesting development about crypto adoption in the US particularly in California but the big question is how they can implement that proposal if it can violate the US constitution? It looks uncertain to me. so only time can tell if it was implemented or not!
