Treasures
I think haypi should sell treasures for money on the game as well as coins. Make the prices of the treasure the same price as the maximum you can sell them for, so no one loses out and it means you cant just buy them and sell them on the market and make lots of money! This might be a way of keeping people playing since i know a few people have quit because of how long they had to save up to get a medal and when they had enough there were no medals there to buy!
