I bought extra coins a lot of times each day, but watched a lot of videos to to earn coins too and boosters, they got fly and stopped ads so i would use up all my coins and buy more, sneaky, no i didn't buy anymore coins, they took ads away so i would have to use up coins i had thinking i would spend more money, spent a fortune on this game in the few days i had it, so i uninstalled, they are just out to make money
