It seems to me that the time for "absolute NO" has come and gone, and at this point the best governments can realistically hope for is playing the game in a "reasonable" fashion, in a similar way to how self-employment income is approached. Yeah, you owe it... and it's up to you to report it... and if you're driving a Lambo on claimed income of $18K a year, we're gonna audit the frak out of you.
I'm inclined to agree, @denmarkguy. I'm interested in what you said about Switzerland, Greece, and Turkey, though. What do you mean by "Crypto friendly"? I'll have to check out those countries.
