In a post that I created yesterday, I explain that powering down with the current compounding interest rate of STEEM Power does not reduce your ending balance of STEEM Power.

You might be interest in taking a look at the post:
Power Up your Retirement/Savings with STEEM Power!

I wrote an earlier post about STEEM Power's compounding interest rate in:
Everlasting STEEM Power; Why you should Power Up!

I do not think the STEEM Power whales will ever lose enough STEEM Power to lessen their influence. But I do believe that some of today's minnow can attain whale status in the future.

Steem on,
Mike
