It's weird though, because somebody must be buying the cards, I guess it's a case of there being more games with cards than ones you want to craft badges for.
I honestly think that the people buying the cards are speculators and people who think they're being super clever and somehow beating the system by selling a card for a few cents more than they purchased it for.
Valve won't give two shits because they are making money every time that happens, and with the speed that cards are getting snapped up, there's a clear revenue stream of pure profit going into Gabe's back pocket 24-7 at the moment.
So I think we essentially have four groups here:
1 - Those who are attempting to craft badges
2 - Those who just see the cards as a distraction and sell them ASAP for Steam moon money
3 - Those who are buying every card they see to speculate against
4 - Those who are flipping cards to make profits on the margins
Ultimately, I can see the whole thing tanking, which instantly takes care of 3 and 4. 2 will be relatively unaffected, and 1 will be able to get on with their crafting. Maybe then, booster drops will increase.
