IMHO this will be a gigantic mistake , or it's a sting to catch unreported income ........................http://www.breitbart.com/tech/2018/02/12/arizona-senate-passes-bill-that-allows-citizens-to-pay-taxes-in-bitcoin/

So what other fake money are they willing to accept? Bit Coin is a non regulated currency, this whole thing will backfire in their face. Someone sends in one bitcoin, worth 17k and the next day when they cash it, its value is 1200 bucks, who's gonna make up the difference? How can the governement accept a currency that they dont create or back?

Well, they already accept US Dollars.
