Hello

Someone know why ANBA give different amount of gold according to people/game?

I am level 42 and I have always just 1925 coins with ANBA since level 30 (but exp increase when I level up, not coins )
but basically, a lot of people earn more!! and I would like earn more too..

Can I do something or am I not lucky?
Is it normal or is it suppose to increase too ?

thank you and have fun
