You must also be an active person to keep update with the latest news. You must also search for an active telegram group that was discussing about the news that come to the crypto market. Remember that some people may not update with the latest news. You can use the announcement thread to get the latest information but some thread lack of update. The only best thing to be active and join in the telegram news channel. You will be rarely seeing people to talk about the coin before it was booming. I see that so many times people have been doing this thing on the speculation sub section.
You can to go there but there's no guarantee if you can get what you are looking for.
