Good post.
I am still learning about Steem and how it all works. I found your article interesting and informative. I have a couple of questions about whales.

1. Are whales just investors using steem to make a profit?
2. If most of them don't write articles how can they upvote other whales?
3. What is the difference between a whale that has a million steem or someone that rents a million steem, like @minnowbooster, for example?
   Thanks again!
