"The mayor told host Stuart Varney that Miami is looking into allowing citizens to pay taxes and fees to the city in bitcoin."
I think this is the most relevant of that interview. Someone bullish on Bitcoin, OK, it's the norm these days, but a mayor considering accepting the payment of taxes is not at all usual. I hope that they do implement it. And that many more will follow.
