I've gotta give this a listen soon... Don't know if it's been suggested, but playing the "If I Were A Steem Witness Game", my compromise offer on an accelerated power down would be to apply it to Justin's accounts and not the exchanges. By personally placing millions of new Steem on each of the exchanges, Justin can restore their liquidity and fulfill the assurances that I believe he made to them, while relinquishing witness voting power as Tron says they are willing to do.
