Remember, Steem Dollars provide 10% annual interest
If you decide to Power Down your Steem Power a smart thing to do with it might not be to put it into your fiat bank account where you could have to deal with inflation and other issues. A smart thing to do might be to Power Down when you have enough money that you can put it into Steem Dollars and either live off the interest from Steem Dollars or let it compound. At 10% a year if you're a Steem whale with $400,000 then you'll be getting $40,000 in Steem Dollars every year.
You could reinvest that into Steem Power or you could spend it as you please.
Oh yeah and I guess by law I have to say none of this is investment advice. This is just my opinion based on common sense understanding of Steem Dollars, compound interest, and it's what I would do if I had the Steem Power to do it.

Is there going to be enough buyers to offset all the Steem retirees powering down and cashing out in perpetuity?
