Look at the numbers on the left side of the graph and then pay attention to the right side of the graph. 2500 coins were dumped since August 10. That's an average of $300K a day. Granted the volume right now is $30 million but most of that volume is day traders and bots. Dumping $300K can create a huge amount of volume when all the day traders and bots react to it, never mind the weak hands.
