What is the need to have another group out of this community, whatever altcoin and bitcoin discussion could find here so why trying to push people to your group for a discussion that has never hold here before or what?
Most of this groups always ends of someone sending you unsolicited pm which I don't always like joining such groups, but however any discussion you think is worth discussing if you don't find the topic already created you can make your topic here and people could openly comments and i think through here you might get the best response from the educated and reputable users.
