I definitely love this "what ifs series". This is a very nice question @ehiboss as I am sure now that the price of steem has drastically reduced, a lot of steemians would be praying for an increase, and the scenario you painted of the price of steem being $100, with 500,000 steem power would be a dream come true for all.

I would pick option B and C because I am not very busy, and can curate cool articles at the moment, so option C is out of it.

I would power down half of my steem power, and keep the cash, then I would use the remaining half to curate quality posts so that other minnows can also benefit from it.

But then, I can never really be sure of what I would do with it because, saying things like this now could change when this comes to pass.

Once again, nice one @ehiboss. My prayer is that the price of steem should increase soon.
