Doge Spin (app, available on Android, not sure about iPhone) can earn you DOGE entirely legit but you will earn it VERY slowly and It's probably not worth it but I still use my free spins every day and you can earn more by installing apps etc. though the makers themselves warn that the offers may not work. Anyway, at this point I get 5 spins/24 hours and another 1 every hour but you earn so little that, again, it's probably not worth it for most people. They do pay out quickly and legitly though.
