Well I personally would power down half of it and put it into Bitshares, becoming a multi-millonaire a few years from now. But that taken aside :P

It's one of the issues I see with Steemit, a whale with a lot of influence (SP) needs to actively, on a daily basis, and manually, curate posts in order to benefit the Steemit platform as much as possible. This is however pretty much undoable, and why voting bots are so frequently used (well that, and circle jerking of course ^^). There should be a way to delegate your SP while still earning curation rewards, so someone who is willing to invest its time to curate, could potentially take a small cut. Secondly I believe voting should be restored on a weekly basis, having 70 votes a week (intead of 10 a day) which could (if choosen to) be spent all in one day. < This one might bring some complications with it, but it's open to debate.

I know... this doesn't really help you answer your question... xD
