To sell it.

Yeah I understand that but what is the point in powering it down? Why not just keep it liquid? How much is the interest you earn?

Well for an INVESTOR who has CAPITAL will prefer powering STEEM into Steem Power which will allow ONLY 1/13th of it to be at RISK of BAD ACTORS/HACKING per WEEK.

This increment of liquid CAPITAL should minimize THEFT or LOSS if ANY.

Just my 3cents worth being Frank

People power up their liquid Steem so their upvote has more effect and they also will gain a lot more curation rewards from their votes.

If you believe in Steem long term, Steem Power is a good choice. But just buying some Steem to sell later could be wise right now profit wise.

There is interest earned... My SP increases everyday on its own.
