so a buy low sell high, normal stuff - so as long as you convert only once from usd to btc, seems like there would be no risk if 'making money'
ask their support if they would track the buy vs. sell price and issue a 1099
Agree: if you never convert BTC back to dollars it shouldn't be taxable. But if you were to buy low and sell high that would be taxable (I'm pretty sure).
I've answered a few of my own questions with research. Circle does not issue 1099s (which means they wouldn't be reporting any realized gains to IRS). If you were realizing gains on USD-->BTC-->USD conversions you'd have to keep track of your own basis and report it yourself.
