To promote own app in flexible way… for example, I earned $100 and immediately I can use it for app promotion in the same network.
I know that:
-millenial media allows but we have to wait 45 days before use funds ;/ not acceptable
-appbrain allows but net30 before use funds, not acceptable but better than millenial
-admob had this but probably deleted option
-mobilecore had house ads but in the past and they are closing
any ideas?
I think Applovin allows it and Appnext also allows it
Applovin not allows. Appnext yes but every transfer needs manual action, so it’s not for example if you have 50$/day and want to reinvest it immediately 
have you tried appbrain , they have this option already
Yes, I tried but they have net30, not automatic transfer and spend. I mean earn>spend>earn more>spend more> earn moooore> spend mooore, to create snowball
Heyzap I believe immediately lets you transfer funds for house ads or for advertising.
But heyZap earnings are very very less compared to used mediation networks with heyZap…so we get vey less from heyZap …
Chartboost allows you to transfer earnings and use them to advertise (minimum $100).
