Try searching on Telegram. Some communities are active on Telegram only.
The problem with telegram groups especially crypto discussion related ones just like Facebook groups, is that they are always filled with spam referral links of different ponzi schemes and HYIPs if no one does serious work to moderate the group.
For example

My advice to OP is, Just stick to this forum where moderation is awesome.
