Spotting a good community:

Good:

Active community with many different kinds of people

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

Some people go on rocketmoon style sites and just buy 30 bucks worth of random shitcoins that are just made
