That's huge news I wish I was a citizen of that country but it won't he possible.
I just hope other world leaders also realize this and start accepting bitcoin as it's really hard for me to decide what do I do with my coins the only problem with this would be they might find out about our holdings and trouble us later
Arizona is a state, not a country, so this isn't as big as you might be thinking it is.
The news is definitely big, but of course, it needs to be carried through with. Just having a consideration isn't good enough these days...
I see a lot of issues that could arise for the state if they go along with this plan. If there's a pretty big fluctuation, there's a good chance that they either end up with less money than they should have for their taxes (in terms of USD), or they could end up with people who paid for their taxes with bitcoin and ended up missing out on a big rise, which would make the people not very happy.
