Yeah, telegram channel have huge followers. I hardly seen 2-3 project with such huge followers. AMA session for these 100k followers would be awesome.
Of course that sounds great, but how many of the 100K would participate in the AMA? 20, 30? it's always the same, a project launches an airdrop, the telegram channel gets many new members, but they do not look anymore after the Airdrop.
But that is not important, the main thing the team publishes there constantly new information, because that's the purpose of the channel
And I'm happier with really interested participants, rather than the constant questions "when airdrop?"
+1 and well said. However I think the number of followers on those channels matter for exchanges. For some applications, I've seen they ask for the number of followers in the different channels they have. So I think that is where those numbers matter.
