Finally full nodes now, first milestone. But the price is dumped, buy the rumor sell the news? 
actually it's not full nodes, cause they are not public. Sasha need another couple days to test and fix some stuff. He just gave to bittrex another version of their servr nodes and called it Fullnodes...but they are not. That's why price went down.
What has been provided to bittrex and other waves exchange is THE FULL NODE VERSION. Sasha need to make sure that it is working properly before releasing it to public. It makes sense to fix any last minute bugs (if any) on a limited number of nodes than to fix once it is public. If no bugs are found in next couple of days THE SAME FULL NODE VERSION will be made public.
