no need to track other accounts. just post, get rewards and calculate by yourself. You will find that at least 75% of rewards will be shipped to your wallet. the remaining 25% or less will go to curators who upvoted you. No fees.

Initially all the tokens were mined into existence, several months later it was decided to remove the Proof Work portion of the consensus algorithm via a hardfork that was approved by the community via the witnesses.
