I don't think anyone with $100k to invest is putting it into STEEM Power and then just posting a bunch of crap and upvoting it. At 100k SP a 100% upvote is only about $10. If someone invests that kind of cash they are gonna work to make sure they get a positive return on their investment, which means that the value of STEEM goes up, which benefits all of us.

We actually WANT people to be investing their money in STEEM. Check out this post which explains why one of the big problems with SteemIt is that people are NOT investing: https://steemit.com/steemit/@initforthemoney/steemit-s-three-major-problems
