Can you earn money by ReSteeming?

Short answer: Yes.

If you vote on a post and resteem it, it gets noticed by more and more people and you will be rewarded with a Curation reward.

At the beginning the reward is very low, around 0.001 Steem. But if you earn more and more Steem Power the higher the reward are. But don't think its that easy, if you reach more than 20 - 25 votes per 24 hours your voting power gets decreased (You can see your voting power here: https://steemstats.com/#!/).

So I hope this post can wipe out some questions about the topic around ReSteeming.
