For insider trading, someone need to hack into Kosmost email account as he would not tell any of the Team members what the news are..... And we are used to that. Nobody even asked him.
you are assuming two things..
1) that kosmost is the only guy that knows if a deal went through or not.
and 2) that he would not tell anyone.
as for point one.. it takes two parties to make a deal... whats to say that the people making the offer didn't tell their friends?
as for point two.. how well can you really know anyone who you have never met?
I don't know about you but I certainly do not trust anyone 100%, not even the people I know in real life.
therefore it would be unwise to rule out insider trading until we get more information.
I am not saying that it is insider trading.. but at the same time I can't say that it isn't insider trading either.
I'm not making any assumptions at all.. just speculating and helping other people with their speculation lolz.
