Spotting a good community:
Good:

Active admins actually communicating with the users
A website for the coin
Presence of well-created bots
Bad:
Broken English from ~half of the community + admins
Spamming of rocket ship emojis/stickers
Large community with almost no activity
Large presence of "FUD" without much response from the community
