I like the trading post idea to swap directly with another player but would not be able to afford to pay crystals for the service as I'm on iOS aka apple. We don't get the same opportunities for free crystals, I have only received free crystals for doing the challenges and to download other TinyCo games (5 per challenge and 10 per download just isn't the same).
