The exact criteria for choosing a coin?
Everyone talks about a "strong community"
I think sometimes you need to explain more precisely
If you want to put it briefly - do not choose projects with only a large community. Choose fanatics. One faithful one is more important than ten greedy ones. Only such a project will make you rich.
This is not an easy job
But it is an obvious and necessary job
I can talk about this for a long time, and I will definitely continue to do so
Simple advice on how to find a project with fanatics:
Choose among projects that are several years old
Start searching on Bitcointalk, reddit, discord
In discord you can communicate personally with people
In the rest - look for posts from five years ago
Look at their authors. Look at recent posts. Find regular commentators. Find their first messages
If they were written a long time ago - this is a good sign
But that's not all
The main thing is that among the discussions there are technological nuances, a discussion of where the project is heading. A share of criticism from old-timers is not a bad sign.
Trust an experienced hunter - there are many old projects that no one is interested in discussing all the time
Sometimes there are local stars in fan communities
This is a great sign
Good hunting
