I used to love this game and would spend the occasional dollar on it as I enjoyed it, but I think I speak for the majority of us when using coins to buy chests for cards we are wasting our coins. Your lucky to get 1 new card every 5 billion coins. I tested this out I spent 32 billion coins and got 5 new cards! That's ridiculous and now you have pumped up the price to buy chests when it isn't even worth it any more. Fix this or at least make an option we can use our spare coins to buy spins.
