There's already PeerHub, accepting sale of services and products, and that's in Steem and not Bitcoin, which should theoretically (but not really, as I've explained in my article) keep the price of Steem up (as we wouldn't need to sell Steem for Bitcoin, in order to obtain said products and services).
The truth is that the underlying mechanism of Steemit is flawed and this is something that the founders, @dan and @ned, need to change. Money printing should be reduced significantly or even stopped. The actual value of Steemit should be confirmed by recognizable business agencies or through offers of known social network competitors. This will bring investor and cryptocurrency trader confidency back.
I've thought of one thing to drive the price of Steem up, but it's it more of a joke - invite dissidents or whistleblowers. If governments want to silence them up, they can buy Steem to become whales and downvote their posts. In fact, it's quite possible that with enough money, they can wreak censorship havoc to the entire network, downvoting everyone's posts.
