50k?!?!? Scammers

Without any notice or improvements to get more coins in the app, you just go from 12500 to 50000 to get a 5€ gift card.. this is a clear abuse of the app you make and you are surely looking for cash since you couldn't do the math to have a sustainable model for your app.. 

As they say, Karma is a B.. hope it catches you soon 😉
