I am a gambler first, collector second, buyer third (not on your list), trader fourth and seller last. In fact, I usually sell as a way of acquiring chips I can't get by trade, so I am effectively trading chips for chips. My sell money almost always goes back into chips. By the way, my trading may be more than my buying at times and at other times, I buy more. It goes back and forth, sometimes due to lack of chip funds.
