Hey DenysM!
Again I appreciate your due diligence.
As I said before there are new contribution addresses every 20/30 users, the two you have are 2 of the addresses that have been assigned to you.
Many ICOs do this for security purposes, for example Quantstamp undertook a similar method for their ICO.
I agree the telegram channel is quiet at the moment, I believe everyone is patiently awaiting the ICO's conclusion.
And lastly, our association with the bounty manager in question was unfortunate for this projects reputation. However, he did do his job well for this project and all the bounty funds were distributed to participants upon it's conclusion. As for his other projects we don't have any comment as we are not involved in any of them. If you have issue with him I would recommend taking it to him directly.
EDIT: The likely reason for the number of bots in the channel would be people taking advantage of the telegram channel airdrop we are currently running. It is an unfortunate side effect of running such a promotion but it has helped with the popularity of the project.
