Either you need to invest more $ into buying more or you need to engage and provide more and more value. By providing value you should get more upvotes on your posts but also by leaving value on others posts you will build tokens on those platforms for when/if that person upvotes your comment.
For example on a majority of my posts I tag a lot of the general blogs.
A single vote from me for someone that comments on my post can net CTP,HIVE, Neoxian, Ash, Archon, BPC, Palnet*maybe they changed their rewards system recently
