I find that the pipeline for me goes something like this:
I go on crypto twitter and I read lots of tweets from lots of different people
If something seems interesting to me and I want to potentially invest, I go to their Discord
2a. If they only have a Telegram, it's a shit project. Avoid
I join and lurk for a couple of weeks in their #trading channels, if they have one, I check out their memes channel(s) and I shitpost to see what kind of community I'm dealing with
If the dialogue is good and people are intersting to talk to, I invest in the crypto and stay in the community as long as the community is interesting and engaging
I delete my discord account and get another one if need-be, which usually means I was banned. If I'm banned, I divest from the crypto and I clean house and try again.
