My solstice and blue moon dragons pull in 316 each per minute x 3 which is significantly lower. (Yet higher than 2 rainbow per habitat at 400 per minute). However, when I wake in the morning my earth habitat is only worth $75,000 and my large sun and moon habitats ( depending on how long I sleep ) are always worth $400,000+ each. I'm a working girl, so I can't always check in at work as often as I would like. It's all about how frequently you can check in and pick up the coins. An even faster way to earn dollars is picking up party hats. For me on level 40, visiting one persons islands is worth $48,000 - quicker than any panlong army or any other habitat. I always encourage people to go for the party hats - it's a nightly ritual for me!
Happy breeding, and happy coin collecting - may the wizard be with you with magic wand in hand!
