I was thinking ... is there a better country to live in than the US as far as taxation is concerned? Eventually, once I am trading for a living, it would be nice to trade as a citizen in a country other than the US to avoid the heavy taxes here. Are there any catches to doing that, such as eligibility to trade on exchanges, or to maintain a retirement account like a Roth IRA? I'm just speculating for now, but in a few years, I may consider it a bit more seriously.
