"The Big Pump Signal" is a Telegram group of traders who have decided to pump and dump various coins every few days. They have approximately 50,000 followers who may contribute to the pump and dump announcements.
Example of their announcement:
Dear members,
For today we have a different setup. Not a ussual pump. We are spreading news again, just like the OAX pump, one of our most succesful pumps.
This time you have the ability to earn a prize if you retweet and react on the tweet. Just like yesterday's give away, we will be giving away 2x 200$ sponsored by Althansia (one of our Discord members) . To win: Retweet, like and react on the news tweets and upvote the reddit post. We share these news posts, so we can get outsiders in the pump to optimize the profit of our members. Right after the pump, we will announce two winners.
Also, after the pump the invites on Discord will be turned off for a small while. We are upgrading and improving the current system and implementing some anti-spam features.
Let's make this a pump we will never forget!
The Pump team
