Lol I don't think anyone would wait for dumping. Yesterday when the new chain was launched, the price immediately dropped by 33% on both Binance as well as Bittrex. But the beauty is that the deposits and withdrawals were on hold in both the exchanges.

It could just be a simple trading that itself dropped the price of Steem. The dumping hasn't started yet. It is disabled for now until the listing and other stuff is sorted out. Let's wait and watch. I guess it will take a little more time.
