I'm not really sure how they planned to do it. It sounded like using HIVE to buy back SME, but I don't know if that will be done through the TribalDEX diesel pool or the exchange. I think SME total supply is 90 trillion, with 2.3 million being created each day until that total supply is reach, which is essentially forever. I'm not sure exactly how they are working out power up packages though.
