I am sharing another Youtube video because I found this one very helpful. Maybe when you got a payout from your posts you have already wondered what curator rewards were. I did not know what they were so I found this video in which it is all explained.
Curator rewards are basically 25% of the rewards that is given to an early upvoter with a lot of Steempower. The more steempower the bigger your share is. In this video it is explained in a lot more detail so check it out.
