If you can make it high in the trending tab people might actually see your post.
And the more people that see it, the more people that vote on it.

Further, voting bots look for people that have good payouts to get that sweet curation. So, high paying posts, attract these voters.

So, if you really get $100 for $100, then one should do it all the time.

Of course the better way is to develop a group of actual readers who add you to their vote bots. Then you get the $100 without paying the $100.
