Let's say 50% active users, that is 5 million, and using 1 time per week, maybe 3 ad loads for example, that is 15 mil. ad loads per week or 60million ad loads per month.
Let say just for example he earns 0,25$ per 1k impressions, that is 250$ per 1 million impressions or 15k$ earnings per month
but this is just my fucking calculation...
