People were dumping since we were at 6 satoshi around mid June (over 6½ million Marketcap) when we were at the 5% rate generating Millions of new coins per day.
ULI activated and some are still dumping at a slower rate, the great thing now is they will run out of coins to dump , where as before they had a never ending supply of free interest to drop. It will take some time, but the price will stabilize and then grow, economically it is the only logical outcome.
