I don't know about anyone else but buying, selling, and/or trading keeps my interest up. There isn't too many that I get attached to other than my CS or maybe a few others. I'll try something out for a while and send it down the road. Sometimes I come out ahead(in my mind), sometimes it's even and then sometimes I get the shaft but that doesn't bother me. Like I said, it keeps me interested. Don't get me wrong, making out or making a profit is nice but sometimes I just make a deal because I like what's on the other end.
