Recommend a decent site to monetize quality traffic

I have several sites with movie sites, I have a steady 2300-2700 users per day, most of them are citizens of the USA, Canada, I have been monetized for more than a year adsterra, but for the last six months, the payment for traffic has dropped 3 times! And it becomes not very profitable for me, please recommend some other sites, maybe someone is interested in my traffic for little money!
