Why does he need to power down both @val-a and @val-b at once? Does he REALLY need to sell 400,000 Steem per week? Does @michael-a also belong to him? However @michael-b is not powering down. Will the Poloniex and Bittrex whales buy out the dump or will the price drop from this? Or maybe he's just waiting for a megapump to cash out some liquid Steem.
