Telegram is adopted widely by the “crypto community”. But Monero should not be apart of this, as it’s a centralized platform doing zero metadata protection and only encrypted on mobile. Here’s an excellent video you can send your friends who request you to message them on there: https://video.simplifiedprivacy.com/why-telegram-sucks/
Just joined it as well… will promote on social media if that’s OK? On my xmr people;)
Feel free the share the group join link fat and wide. As far as I am concerned, the more Monero enthusiasts in there, the better.
