See again though that isn't an answer to the question I asked is it? I didn't say is it good or bad, do you like it, I said what would the impact be. This is research for a podcast not me being a dick.
I don't think anyone in their right mind would trade btc for another currency (when it's taxed), so I doubt it would have much effect. No tax on goods purchased with bitcoin would have a big impact imho. Lot of guys out there who want to buy things with their stack but can't justify giving 20% to uncle Sam.
