Cryptocurrency markets have experienced explosive growth over the past decade, attracting millions of investors worldwide. With daily trading volumes exceeding tens of billions of dollars, digital assets like Bitcoin and altcoins have become fertile ground for speculative behavior—and market manipulation. Among the most prevalent forms of fraud is the pump and dump scheme, where coordinated groups artificially inflate a cryptocurrency’s price before selling off their holdings at a profit, leaving unsuspecting investors with significant losses.
This article explores the mechanics, real-world impact, and detection methods of cryptocurrency pump and dump operations. Based on academic research and data-driven analysis, we break down how these schemes operate, examine case studies, and introduce advanced detection techniques that outperform existing models.
Understanding Pump and Dump Schemes
Pump and dump schemes are not new—they’ve existed since the early days of stock markets. One infamous example occurred in the 1920s with RCA Corporation stock, where a group known as the “Radio Pool” drove prices from modest levels to $549 before collapsing them to under $10. Today, these manipulations have migrated online, leveraging instant communication platforms and decentralized exchanges to target low-liquidity cryptocurrencies.

In the modern context, a pump and dump involves three core phases:
- Accumulation: A group quietly acquires large amounts of a targeted altcoin.
- Pump: Members simultaneously buy the asset, creating artificial demand and driving up the price.
- Dump: Once the price peaks, organizers sell their holdings, causing a rapid decline and trapping latecomers.
Unlike traditional markets, cryptocurrency exchanges often lack robust regulatory oversight, enabling such schemes to flourish—especially on coins with low market capitalization and trading volume.
The Anatomy of Pump and Dump Groups
These fraudulent operations are typically orchestrated through self-organized communities on platforms like Telegram and Discord. These groups operate publicly, allowing anyone to join, though they often feature tiered membership structures that reward recruitment or payment.
Group Hierarchy and Incentives
Most pump and dump communities use a hierarchical model:
- Admins/Leaders: Control all decisions, including timing, target coin, and exchange.
- VIP Members: Pay fees (often in Bitcoin) or refer new users to gain early access to pump signals—sometimes seconds ahead of regular members.
- Common Members: Receive signals later, reducing their profit potential.
This time advantage is critical. Even a 10–30 second head start allows VIPs to buy at lower prices before the price surge hits public awareness.
Communication Structure
Groups organize their Discord or Telegram servers into structured sections:
- Info & How-Tos: Rules, FAQs, and guides on participating.
- Invite Rooms: Bot-powered tools to track referrals.
- Signal Channels: Admin-only zones where pump announcements are posted.
- Discussion Forums: Member-driven conversations about strategies and results.
To prevent automated bots from exploiting signals, admins often obfuscate messages—posting target coins in distorted images that only humans can interpret quickly.
Execution Strategy
A typical operation unfolds as follows:
- Pre-Announcement: The group announces an upcoming pump, specifying time and exchange.
- Target Reveal: At the designated moment, admins disclose the target cryptocurrency—usually via image.
- Coordinated Buying: Members execute rapid buy orders.
- FOMO Generation: Admins encourage members to spread bullish news on social media to attract external investors.
This last step exploits Fear of Missing Out (FOMO), luring retail traders into buying near the peak—just in time for the dump.
Case Study: The Big Pump Signal Group
One of the largest known pump and dump communities is Big Pump Signal (BPS), which grew to over 200,000 members across Discord and Telegram by early 2019. Between December 2017 and January 2019, BPS executed 32 documented pump-and-dump operations—27 on Binance and 5 on Cryptopia.
Their most notable operation targeted SingularDTV (SNGLS) on May 10, 2018. The price surged dramatically within minutes, generating over $4 million in trading volume (equivalent to ~80 BTC at the time). The group used aggressive marketing—referral programs, Bitcoin giveaways, and social media campaigns—to fuel exponential growth.
Operational Evolution
BPS refined its tactics over time:
- Initially revealed targets in plain text; later switched to obfuscated images to block bots.
- Stopped announcing price targets after members began selling prematurely.
- Shifted focus from small-cap to medium-cap coins as their capital base expanded.
- Leveraged fake news accounts (e.g., impersonating John McAfee) to amplify hype.

Detecting Pump and Dumps in Real Time
Protecting investors requires early detection. Traditional methods rely on sudden price or volume spikes—but these are common in volatile crypto markets and lead to false positives.
Our research introduces a more accurate approach: monitoring rush orders, a proxy for market buy orders executed at any cost for speed.
What Are Rush Orders?
A market buy order executes immediately by purchasing available asks in the order book. In low-liquidity markets, this can cause sharp price increases. While rare in normal trading, they dominate during pump events as group members rush to buy.
Since exchange APIs don’t label order types, we infer market activity by aggregating trades executed within the same millisecond—defining them as rush orders.
Detection Model: Features & Performance
We trained machine learning models using Binance trading data from 73 confirmed pump events. Key features included:
- StdRushOrders / AvgRushOrders: Standard deviation and average volume of rush orders.
- StdTrades / StdVolumes: Variability in trade count and volume.
- Price volatility metrics: Moving averages and deviations in closing prices.
Using a Random Forest classifier with 25-second data chunks, our model achieved:
- 92% F1-score
- Detection within 25 seconds of pump initiation
- Outperforming prior state-of-the-art models (e.g., Kamps et al.) by over 30 percentage points in accuracy
Crucially, our method detects pumps based on behavioral patterns, not just price changes—making it more reliable amid natural market noise.
Why Rush Orders Matter
During a pump on VIBE (September 9, 2018), rush orders surged from near-zero to over 15 BTC within seconds—while price-based indicators lagged. This confirms that abnormal buying behavior precedes visible price movement.
Our classifier also identified previously undocumented suspicious events—such as unexplained spikes in Agrello (DLT) trading—suggesting undetected or obscured manipulations.
Frequently Asked Questions
Q: Can pump and dump groups manipulate major cryptocurrencies like Bitcoin?
A: Practically no. Even the largest pump operations (~80 BTC) cannot meaningfully move Bitcoin’s price due to its deep liquidity and high market cap. Simulations show such efforts would shift BTC by less than $10—dwarfed by normal volatility.
Q: Are all low-market-cap coins vulnerable?
A: Yes. Over 90% of pump targets have market caps below $50 million. Many trade less than $1 million daily—making them easy to manipulate with relatively small capital.
Q: Can exchanges stop these schemes?
A: They could. Exchanges have access to granular trade data—including order types and user identities—that would make detection easier than for external researchers. Some, like Bittrex, have reduced pump activity by enforcing anti-manipulation policies.
Q: Is it possible to avoid detection?
A: Only partially. Gradual “pre-pumping” might evade detection temporarily, but it risks insider leaks and erodes member trust. Most groups prioritize speed over stealth.
Q: How can investors protect themselves?
A: Avoid coins with sudden spikes in trading volume without news. Use tools that monitor order book dynamics. And never follow anonymous “signal” groups promising quick gains.
The Bigger Picture: Regulation and Investor Awareness
While technology can help detect fraud, long-term solutions require collaboration between exchanges, regulators, and investors. Possible measures include:
- Real-time monitoring systems using behavioral analytics.
- Temporary trading halts when abnormal rush order volumes occur.
- Stricter KYC/AML enforcement on high-risk altcoin pairs.
Ultimately, awareness is the first line of defense. Understanding how these schemes work empowers investors to recognize red flags before it’s too late.
