You can sell cards but they only go for about $0.20-$0.30. If you don't care about your steam level then just sell them. The only benefit you get from steam level is a higher chance of getting random card drops.
So it is a never ending upward spiral for level 1000 steam account?:buy games, get cards, play games, get cards, craft badges,steam level up, more chance for cards, more cards, craft badges, higher steam level, more chance for cards, more cards, more badges,...
Clever trick to get people to buy games and play them on steam. I do admit that I want to have the badges of the games I enjoy most as a sign of pride. Do all games get you badges when you play them? And how old is this trading card business?
