I had all the Jazz players available, but then sold a few of them. I'm going to hold on to the Jazz because I think their value will go up if they can make it to the finals. Also I think beta will end this summer and all the cars value will go up then. They are also planning their first commercial during a game. I'm hoping it's during the playoffs this year and all the cards will jump, at the very least if that happens all the valuable rare/series 1/rookie/good number cards will take a big jump.
So far I've made a profit of 2k. I'm sitting on about $3.5k of cards that I could cash out and and be even for those leaving me with the 2k profit. But I'm probably just going to sell a couple cards soon so that I'm even overall no matter what happens and hold on to the cards I think could be worth a lot later.
