I'm already crazy

Well ! You want to earn more coins,that sounds good ,. First complete your daily task ,and if you want to do something extra than you can read news , article , audio , video, games . But I would like say one thing to you ,Becuse of gaining more coins don't take more lessons in a day ,it can stuck your mind., otherwise it's depends your choice or interest . Good luck !!
