I can confirm that mine aren't selling for crystals anymore either. Hopefully they change it back because of the poll being lopsided in favor of crystals. However, I can see them keeping it coins because crystals are so hard to come by in this game that even 5 or 10 for a common dino is probably more than they want to give away. I probably won't ever sell mine for coins because eventually coins are plenty easy to come by, whereas crystals never are. I wish all the lower level players could realize that, but it is something you only learn over time.
