well that's just it. I see an occasional news story that says so and so sold bitcoin and somehow it was made out to be illegal activity. Now it does seem to usually involve other activity like drugs or taking custody and swpping etc.

But like if I just offer to sell bitcoin at a booth at the Miami conference p2p is there some threshold where it becomes illegal? If no one says anything about doing crimes and I don't know you is there something else that triggers illegal activity?
