Down Cpm and expensive purchases in Metabbs

Mostly in Rush-hours posts goes higher than 3$ ... So sometimes you are unable to purchase your own post .. If you buy your own post in such high price it gives you loss because you purchase it in 3$ and earning  0.5$ from it..But if you are not buying your own post than your are not receiving any Adserver or earning ... Your effort goes waste... 

Now situation is difficult  you can't buy expensive but if you are not buying your own than you got nothing 🤔
