What a crypto telegram channels do you know? (by eng)
Don't joint on such telegram groups because they only share spams there and its not possible to trace all the messages send on such channels so as the second post mentioned try to follow the reputed crypto news sites to get the legit news related to cryptos.
My favorite site is coindesk which is also available in apps.
i see that most of the channels and groups shared by users here are legit and somehow well know so i dont think there are spams on here and also they will monitor thier channel more strict so spams will be manageable compare to some random crypto groups thats only want to grow thier group so they will tolerate spams to look like thier group is lively . there are also telegram channel only where you cant write posts , this is the perfect way to combat spams
