This is exactly how I look at it. My background is in equities, so I am always thinking of hedging. IOW I figure if I worry about protecting to the downside, the upside will take care of itself. So I have yet to power down. However, I almost weekly sell my SBD. I feel then the most I can lose is only half my earnings.
Sounds like a very good plan, and since you are a content creator it makes sense to want to have that Steem power for the extra visibility it gives you on posts.
