How scammers are getting rich using social media, scam news sites, and private pump and dump group chats to spread false information about cryptocurrencies
In the largely unregulated world of bitcoin and cryptocurrency, fraudsters are getting rich by deliberately spreading false information … Tweets: @rmac18 and @rmac18 Tweets: Ryan Mac / @rmac18 : If you're thinking about putting your money into bitcoin or other cryptocurrencies, here are some scams to avoid http://www.buzzfeed.com/... Ryan Mac / @rmac18 : Earlier today we published a story about the spread of pump-and-dump cryptocurrency groups like the 70K-member Big Pump Signal. And now, Twitter just shut down @BigPumpSignal's account. http://www.buzzfeed.com/...
Context & Ripple Effects
Ryan Mac's reporting lands at the moment the pump-and-dump playbook went industrial: private Telegram-style chats like the 70K-member Big Pump Signal coordinate buy signals across fake news sites and social accounts, then dump on the pool that bought last. The Outline's follow-up inside the chats showed the structural tell — high-ranking members receive the signal 0.5 to 3 seconds before everyone else, meaning the general membership is the exit liquidity by design.
The story also captures the first platform response: Twitter shutting down @BigPumpSignal's account within a day of publication. But the same month's coverage shows enforcement chasing tactics rather than closing them — scammers pivoting to fake celebrity giveaways and, weeks later, keeping verified badges after changing handles to lend stolen credibility to wallet addresses.
First-order effects
- Twitter's takedown of @BigPumpSignal removes the group's public recruiting funnel, but the 70K-member chat itself persists off-platform where moderation can't reach it.
- Retail traders who joined these pools are structurally guaranteed losers: with insiders dumping seconds ahead of the broadcast signal, the average member buys the top the organizers created.
Second-order effects
- Platforms are pushed into reactive verification work — Twitter probing how scammers retained verified badges through handle swaps shows the trust infrastructure itself becoming the attack surface.
- Scam operations diversify beyond pump groups into adjacent formats: impersonation giveaways and, later, a professionalized paid-promotion market with middlemen like Dapp Centre coordinating influencer campaigns that test the edges of US securities law.
Third-order effects
- If the pattern holds, crypto promotion consolidates from ad-hoc chat rooms into an influencer-industrial complex — the 2021 wave of celebrities like Kim Kardashian and FaZe Clan pushing altcoins to fans is this same mechanism scaled up and monetized.
- Sustained manipulation in an unregulated market builds the case for treating paid coin promotion as a disclosure problem, forcing regulators to decide whether influencer hype counts as a security solicitation.
The trend: Cryptocurrency fraud is migrating from improvised chat-room pumps toward professionalized influencer promotion networks, with platform enforcement and securities regulators trailing one tactic behind.
