I think OP is talking about those crazy doge meme token!
same question for me, where do they get the news of the launching of those tokens!
It easy to pump 10x or 100x for a new meme token if you buy from beginning these days!
..And 100x loss of money when the dump happens.

Launching of tokens are mostly here in the forum. You can see it in the Announcement board it Altcoin section.
