NSAV Holding Inc (NSAV)

That is what happens when an inexperienced trader sells a lot of shares at market. (Not with a limit.) MM's instantly drop their bid and the price shoots down.
People: NEVER BUY OR SELL WITHOUT A LIMIT unless you don't care what price you pay (buying at market makes the MM's raise the offer). If you buy 10M shares at market, then look at the tranches you get, you'll see they go up, the same way the share price goes down when you sell at market. Set a limit. Know what you'll pay and what you'll receive.
