The way you said it i was thinking you were 100% sure, so you just read between the lines... We can never know for certain unless he says it! Even Bitconnect didn't go down in 1 day, there were some people that bought even when the price was low... I'm just saying, i like to play it more on the safe side then to speculate on what is happening, even though i did speculate in a post about the reason he is powering down
Im going to buy more STEEM though
