Is Buying Steem Power Worth It?

Hi everyone,

I wanted to ask the Steemit community if its worth buying Steem Power? I already hold a good amount of Steem but I'm wondering if it would make more sense to convert that into Steem Power?

I'm an avid believer of Steem and do feel this will be revolutionary as it grows popularity. From the research I've done it seems like once I convert Steem into Steem Power I cannot withdraw it all for 2 years (which I'm okay with). Steem Power also compounds while it's in your account... Which is awesome and something my Steem obviously doesn't do. I can also upvote and reward people on the platform for creating quality content which will make Steem better as an overall platform.

Does Steem Power ever go away from your account? I still don't understand the powering up and powering down that takes place and the reasoning behind it.

If you have any advice or suggestions that would be great.
