Wow, I'm such an idiot. I've been trying for at least the last month to fill out the dinos I'm missing (down to just a Bambiraptor and Love Stego now...wasn't in on the bingo where apparently everyone could get one easily) using the Dino Den trick, and since I already had 4 Protos and Dimetrodons due to them being the most common 60 hurry cost dinos, I was just throwing them away. I didn't realize they were still giving crystals for the full-grown ones, I thought that was a limited time thing. After reading your post I went and sold all my duplicates, and made over 450 crystals. Now I have to resist the urge to blow them all on windmills.

As far as your plan, if you haven't already started I'd say it could be tough to get up and running, but if you've been raising them all along and have a bunch of habitats like I do, it is definitely a feasible idea. I'm going to be keeping every "rare" I hatch now and selling the adults off. I'm not sure you can get it to one a day necessarily, but I don't see why you couldn't get close at least. I'll be giving it a shot too, so we'll see how we do.

As far as selling them for coins, can you do that after they are full grown? I didn't see an option for anything except crystals. Either way, if you're doing it to actually raise coins, I would probably go a different route and buy better decorations/shops. I know that dinos are profitable after a certain point, but if you're at the point where raising money is important, it seems it would take too long to start turning a profit and you'd be hurting yourself by stifling growth for the 30 or so days it takes you to get going. Venus Fly Traps and Giants Sapphires/Emeralds are much better if you want to get some cash going mid-game (I wouldn't try this dino strategy early game, too cost prohibitive).

God, I can't believe I missed this idea. I've been wondering how to turn excess coins into crystals, and this is perfect for me since I've already got a ton of habitats. I'd give you a +internet if I could for this idea!
