I sure as heck hope not, although unfortunately I do see it being rather likely in the future. But I keep thinking, to be able to tax something, surely it has to be exchanged into the fiat currency of the nation you're transacting in? Unless governments started accepting cryptocurrency as a form of tax payment, which seems unlikely. I keep thinking that as long as you transact in nothing but crypto, never exchanging into fiat for a purchase, then I cannot see how it could realistically be taxed. But I guess it really does depend on the country you live in and how tyrannical the government that rules over you is. We just have to stay ahead of the curve.
