But do you think paying your taxes in Bitcoin will be a good thing for Bitcoin?
Sure, it's a good thing for establishing legitimacy. What better endorsement could there be than government acceptance? It would mean that mainstream acceptance is inevitable. That's a giant leap from 5 years ago when mainstream opinion said that BTC was only for drug dealers and criminals.
Or is it another way the government is trying to take our Bitcoin?
It's definitely a way for governments to take our coins. I would never pay my taxes in BTC, just like I would never sell after a prolonged downtrend. Both Wall Street and governments want your coins cheap. Don't give it to them.
