For the long term health of the platform I think it's vital for users to get some stake in Steem Power as part of each payout.

• The higher the SBD price the less of each post that gets paid in Steem Power.
  Sure there is a short term benefit to individuals but looking out over a longer time horizon it may be less sustainable. What in effect is happening is value is being taken out of the system at an accelerated rate. You no longer have to wait to power down.
• The second issue I have is (like all cryptocurrencies) it makes it very hard to engage in any form of commerce as you cannot set a price for a good or service over any time frame with certainty.
  I run monthly competitions and it makes it very difficult to set a prize fund as I don't know what its going to be worth in a months time.
