In the beginning, posts paid out in 24 hours, then votes would accumulate every month and payout. But that was quickly changed to one day and one 30 day payout, which was then removed later. It is not bad. You're also working hard to develop an audience. If renting some votes keeps you here and working, then by all means do it. I'm speaking of what is optimal for the platform. If more users were personally curating, you'd have more available votes to attract.
