Just thinking out of the box here. Maybe he is powering down so as to short the upcoming stock market crash. He will make a fortune. Another theory I have is that with the new internet censorship laws coming maybe steemit will be forced to shut down and he is abandoning ship. Also who recommended steemit to me has also just powered down and he was very pro steemit. I am definitely concerned.
