Definitely trading over mining, but trading gives people heart aches as the price fluctuates. I would've said mining months ago seeing today's price, but since the big hashers are all set up now, I don't feel like it's worth it.
I was confused at first too. I think we need a forced redirect to the thread describing these restrictions before allowing general forum access. I see other boards do this with no problems, I think it's a relatively simple script.
