If you want to know about cryptocurrency trading, you need to join different telegram groups.
At least 100k different telegram groups are available; what should I do now? You do not need to check on everywhere for news and events which are impacting crypto space; just following one or two crypto news portal will be enough along with any reputed social media group.
I guess these days you must stay away from any telegram groups and more importantly from all crypto related social media. Because, what I have observed is, almost all social media groups are trying to make people into their pump and dump attempts without letting people aware of that.
