Kingscrown earned $87 on this post thanks to his many followers and their large stake in the Steem ecosystem. A larger account value means a larger say in how much someone will be earning on a post.

Witness Votes and Post Votes are two different things, neither takes out the other or affect the outcome, but both depend on how much Steem you have in your account.

About Witnesses

A witness is a regular person, running a dedicated server with specialized software. This software is open-source and together with all the other witnesses they keep a distributed ledger on what is happening on the Steem Blockchain.

The Steem Blockchain is an open ledger, free for anyone to read and use, and is widely used on pages like Steemit.com (the original) but is also used on for example Busy.org and online tools that read and display data from the chain, like Steemd.com and SteemDB.com

This system is called DPoS, which stands for Distributed Proof of Stake, where Stake is the value of the account that votes on a witness. The chain has many witnesses, and they all need support from the community by voting on https://steemit.com/~witnesses.

I wrote about this in a post a few days ago in Voting for Witnesses Got Even Easier
