** as my understanding hes losing his own curation???

How is the reward pool split between authors and curators?
Up to 50% of a post's payout is awarded to curators (the people who upvoted the post) as a reward for discovering the content. The other 50% is awarded to the author.

If curators vote for a post within the first 5 minutes of it being created, a portion of their curation reward remains in the rewards pool for other authors/curators. This portion is linear to the age of the post between 0 and 5 minutes. As an example: upvoting at two minutes will donate 60% of your potential curation reward back to the rewards pool.
