Or the dev and friends are selling their free coins at 100% profit no matter what the price is. Now i am not saying this is the case here.
Although a smart dev doesn't usually dump like this, at least not unless his plan is to buy back coins cheaply. Typically a dev would dump after the coin gets pumped somewhat. And then it's much better to slowly dump over time, especially as new coin stuff is released or promised (doesn't even have to do anything, just act like something is in development) ... better price overall.
I'm not dumping anything. All I did on the market - bought back. That whole mess amazes and scares me.
There is no "friends" who dump, there is none of my BTCs in ICO. People really are dumping with 50% loss...
