Edit because I don't read good I guess. I missed the whole "for a month" part. Assuming that means the stake is delegated, I can't have an effect on witness rankings, or redelegate to curation initiatives. Also, I'd have to let it go. Whoops :D
- No self-vote. At 50m SP there's literally no reason. Curation rewards from $24000 in daily votes, even if voting at the very end, should be more than enough to live on.
- Shake up the witness rankings. Some people would be happy and some would be sad, but one thing is for sure: things would change. And if I didn't like the results, they would change again, and so on.
- Counteract bad actors. With 50m SP there would be almost no limit to my ability to negate the voting behaviour of bad actors on Steem. I needn't elaborate on who they are.
- Drop random bombs. The idea of this has always excited me. Once a day I'd take a 100% vote and just drop it on someone. New, old, whatever. Someone who I thought deserved it.
- Delegate to manual curation initiatives. I am not a wonderful curator myself, and I think that's okay, because there are some pretty great community curation projects here. I would use a large amount of my stake to support their activity.
- Let it go. Slowly over time, I would power down and distribute stake directly by making purchases, giving donations, running contests, and similar actions. I would also burn a decent portion of it. 50m SP is just way too much for one person to have.
My upvote went to you for your point #3.
That was exactly in my mind too. First - build the own reputation to 83+. (as there is no any other option). Second - make steemit the better place.
