Hi Sean/Brunotreves,
Thanks for the explanation. I am new-bee to SteemIT. I would appreciate if you can help me understand when a post receives upvotes and some $$ amount, when there are no downvotes or flags, why is it that the amount changes. In my recent post I had $2.36 after a few hours the amount had reduced to $2.28, there are no downvotes or flags on my post.

Appreciates your help.
