The world of cryptocurrency offers immense opportunities—but with those opportunities come significant risks. Among the most devastating are "rug pulls," a form of scam where project creators abandon their ventures after collecting investor funds, leaving behind worthless tokens and broken promises.
While blockchain technology promotes transparency and decentralization, the lack of regulation in certain corners of the space has allowed malicious actors to exploit eager investors. According to blockchain risk monitoring firm Solidus Labs, over 117,000 scam tokens were deployed within a single year—averaging nearly 41 new fraudulent projects every hour. In 2022 alone, rug pulls accounted for a staggering portion of crypto-related losses.
Understanding these failures is crucial for anyone navigating the digital asset landscape. Below, we examine five of the most notorious crypto scams in history, uncovering how they operated and what red flags could have warned investors in time.

What Is a Rug Pull?
A rug pull occurs when the developers behind a cryptocurrency or NFT project suddenly disappear with investors' funds after raising significant capital. These schemes often involve creating hype through social media influencers, fake roadmaps, or misleading claims about partnerships and utility.
Unlike traditional frauds, rug pulls can happen rapidly—sometimes within hours of launch—especially in decentralized finance (DeFi) ecosystems where liquidity pools are easily manipulated.
One major warning sign is unnatural token distribution, such as developers holding a large percentage of supply or locking minimal liquidity. Other red flags include anonymous teams, unaudited smart contracts, and aggressive marketing without a functional product.
Even influencers aren't immune to scrutiny. In a recent sting operation, cryptocurrency investigator Coffeezilla exposed MMA fighter Dillon Danis for promoting a fake NFT project without disclosing it was paid advertising—a violation of SEC guidelines. Fans who clicked the link were redirected to a site titled "Did Dillon Danis Scam You?" showcasing charts of failed projects he had previously endorsed.
This incident underscores a vital rule: never rely solely on influencer endorsements. Always conduct independent research before committing funds.
5 Infamous Crypto Rug Pulls You Should Know
1. OneCoin – The Billion-Dollar Ponzi Scheme
Dubbed the largest cryptocurrency scam in history, OneCoin defrauded investors of an estimated $4 billion. Promoted as the "Bitcoin killer," the so-called "crypto" had no real blockchain—its transactions were recorded on a simple SQL database.
Founded by Bulgarian entrepreneur Ruja Ignatova, OneCoin lured victims with promises of high returns and legitimacy, even selling educational courses to boost credibility. Ignatova disappeared in 2017 and remains at large, now listed on the FBI’s Ten Most Wanted Fugitives list—the only woman currently featured.
Her brother, Konstantin Ignatov, took over briefly but was arrested in 2019 and later pleaded guilty to fraud and money laundering charges.
Despite its elaborate facade, OneCoin lacked core blockchain features: no mining, no public ledger, and no way to independently verify transactions. It was, in essence, a classic Ponzi scheme masked as innovation.

2. Thodex – The Exchange That Vanished Overnight
In April 2021, Turkish exchange Thodex abruptly halted trading, stranding over $2 billion in user assets. CEO Faruk Fatih Özer claimed the shutdown was due to a cyberattack and assured users their funds were safe—only for him to flee the country shortly after.
Turkish authorities launched an investigation into alleged fraud and organized crime, arresting dozens of employees and seizing company servers. Interpol issued a Red Notice for Özer, who was eventually captured in Albania in 2022.
Chainalysis reported that Thodex’s collapse accounted for nearly 90% of all centralized exchange-related losses that year. Prosecutors are seeking up to 40,564 years in prison for Özer and accomplices, with over 2,000 victims named in the case.
This incident highlights the dangers of centralized platforms with weak oversight and opaque operations.
3. AnubisDAO – A Flash Crash After Launch
Launched in October 2021, AnubisDAO raised approximately $60 million worth of ETH (13,597 ETH) by positioning itself as a spin-off of OlympusDAO—a respected DeFi reserve currency protocol.
Within 24 hours, however, all funds were drained from the liquidity pool and transferred to unknown addresses. Investors found themselves holding ANKH tokens with zero value due to complete loss of liquidity.
The project had no official website or whitepaper at launch—only a Discord server and an inactive Twitter account. Developers operated under pseudonyms, and the code was never audited.
Chainalysis labeled AnubisDAO a cautionary tale: "Investors should avoid new tokens without code audits and transparent development teams."
4. Squid Game (SQUID) Token – Hype-Driven Collapse
Riding the wave of Netflix's Squid Game popularity, the SQUID token launched in late 2021 on Binance Smart Chain. Marketed as part of a play-to-earn Web3 game, it gained viral traction through influencer promotions and media buzz.
Despite having no actual game or working product, SQUID’s price surged from pennies to over $2,800 in weeks—until developers pulled the plug.
Using a honeypot contract, they prevented most users from selling while draining millions from the liquidity pool. A Twitch streamer captured the crash live as the token’s market cap plummeted from $2.2 billion to near zero in minutes.
At the time of writing, SQUID trades below $0.01, down over 99% from its peak.
5. Mutant Ape Planet (MAP) NFT – Fraudulent Clone Scheme
Capitalizing on the popularity of Bored Ape Yacht Club (BAYC) and Mutant Ape Yacht Club (MAYC), the Mutant Ape Planet (MAP) NFT project launched as a near-identical copycat.
Developer Aurelien Michel, a 24-year-old French national based in the UAE, was arrested upon arrival at JFK Airport in New York. Prosecutors allege he and unnamed co-conspirators raised nearly $3 million by promising buyers exclusive rewards, metaverse land, and community benefits—all of which were never delivered.
After minting concluded, funds were funneled into wallets controlled by Michel, who allegedly used the alias "James" to manage Discord communications before cutting contact.
Blockchain analyst ZachXBT traced millions more in illicit proceeds from similar schemes like Fashion Ape NFT and Crazy Camels, suggesting a broader pattern of deception.
Frequently Asked Questions (FAQ)
What is the most common sign of a rug pull?
A major red flag is when developers hold a large portion of tokens or fail to lock liquidity. Anonymous teams, unaudited contracts, and unrealistic ROI promises are also strong indicators.
Can rug pulls be prevented?
Yes—by conducting thorough due diligence. Check for smart contract audits, team transparency, community engagement, and whether liquidity is locked via verifiable tools like Unicrypt or Team Finance.
Are all anonymous crypto projects scams?
Not necessarily. Some legitimate projects value privacy, but anonymity increases risk. Always assess whether there's sufficient third-party validation and ongoing development activity.
How do hackers execute a honeypot rug pull?
In honeypot scams, the smart contract allows buying but blocks selling. Users can transfer tokens but cannot sell them on exchanges, trapping their funds while developers freely withdraw liquidity.
Is it possible to recover funds after a rug pull?
Recovery is extremely rare. Once funds are moved across chains and mixed through tumblers, tracing becomes difficult. Legal action is possible but often slow and costly.
Which blockchain has the most rug pulls?
Binance Smart Chain (now BSC) has historically seen high volumes of scam tokens due to low deployment costs and less scrutiny compared to Ethereum.
