I actually treat Steem Power as a security feature and its one of the reasons why I chose Steem over Bitcoin.

But I also support the idea of dynamic staking as suggested by @therealwolf and I wouldn't mind if the savings feature allowed longer hold periods.

Having said that, isn't it good to make the staking periods long, so that exchanges have no way of using the Steem deposited by their clients to vote for witnesses, proposals, or to word it another way, their OWN witnesses, and proposals?

I also want to point out that it's obvious, at least to me, that Shorter Powerdown times would not encourage investors to buy Steem since they can already buy Steem with no Power Down times.
