You expect users to be rewarded from other users buying steem power. This is a failed business model.

People already pay for content and will continue to pay for content. If I could buy Steem Power and get higher quality more personalized content then I would buy it if I could with a credit card or bank account. My own personalized information feed would easily be worth it and the more Steem Power I have the higher the quality of my feed.

Steemit isn't going to have to be like Facebook. Speculators and investors are not necessary. What is necessary is an easy way for people who have lots of money to get the content they want.
