A short term interest bearing bond might help, funded by the steem team and steemit whale pod. Buying the bond and holding for a month gets you a nice interest rate, with a bonus for buying the bond with steem directly from an exchange purchase. This would give new money something to invest\spend on, and drive up steem purchases from the exchange while also removing it from the playing field.

If only there were a decentralized smart contract platform that could store registries of debts or promises, and move funds in accordance with set instructions, automatically.
