The Biggest Cryptocurrency Scams in History
The cryptocurrency market, known for its high volatility and potential for massive gains, has also become a breeding ground for fraudsters and scammers. Over the past decade, numerous high-profile scams have resulted in billions of dollars in losses for investors worldwide. This article explores some of the most infamous cryptocurrency scams in history, detailing how they worked and their impact on the industry.

1. Bitconnect (2016-2018) โ The Largest Ponzi Scheme in Crypto
One of the most notorious cryptocurrency scams, Bitconnect, lured investors by promising daily returns of up to 1% through an automated trading bot. The platform claimed that its proprietary software could generate consistent profits regardless of market conditions. Investors were encouraged to lock their Bitcoin into Bitconnect in exchange for Bitconnect Tokens (BCC), which they could then lend on the platform to earn massive returns.
However, Bitconnect was nothing more than a classic Ponzi scheme, where returns were paid using new investors’ money rather than actual profits from trading. In January 2018, the scam collapsed when regulators in the U.S. and other countries issued cease-and-desist orders. Bitconnect shut down, and its token value plummeted from over $400 to nearly zero, leading to losses exceeding $2.5 billion.
2. Mt. Gox (2014) โ The Largest Exchange Hack
Mt. Gox was once the largest Bitcoin exchange, handling over 70% of all Bitcoin transactions at its peak. However, in 2014, the platform abruptly suspended withdrawals, citing technical issues. Soon after, it was revealed that hackers had stolen 850,000 BTC (worth about $450 million at the time), making it the largest cryptocurrency hack in history.
Further investigations revealed that the exchange had been compromised since 2011, with poor security measures allowing hackers to siphon funds unnoticed. The collapse of Mt. Gox sent shockwaves through the crypto industry, highlighting the need for better security and regulatory oversight. Years later, victims are still awaiting full compensation through ongoing legal battles.

3. OneCoin (2014-2019) โ The Billion-Dollar Pyramid Scheme
OneCoin, founded by Bulgarian entrepreneur Ruja Ignatova, marketed itself as the โBitcoin killer.โ It claimed to be a revolutionary cryptocurrency that would soon surpass Bitcoin in adoption and value. Through aggressive multi-level marketing (MLM), OneCoin attracted investors by promising extraordinary returns.
However, OneCoin was a complete scamโthere was no actual blockchain or cryptocurrency behind it. Instead, it was a pyramid scheme, where profits were made solely by recruiting new investors. By the time the scheme was exposed in 2019, over $4 billion had been stolen from investors worldwide.
Ruja Ignatova, now infamously known as the โCrypto Queen,โ disappeared in 2017 and remains on the FBIโs Most Wanted List. Several of her associates have been arrested, but the full extent of the scam’s damage is still unfolding.
4. PlusToken (2018-2019) โ A $6 Billion Ponzi Scheme
Another massive Ponzi scheme, PlusToken, originated in China and spread globally, attracting millions of investors. The platform marketed itself as a high-yield investment program, promising guaranteed returns if users stored their cryptocurrencies in the PlusToken wallet.
By mid-2019, the scheme unraveled when users found themselves unable to withdraw their funds. Investigations revealed that the operators had siphoned off over $6 billion worth of cryptocurrencies, including Bitcoin and Ethereum. Chinese authorities arrested several key members of the PlusToken team, but much of the stolen funds remain unrecovered.
5. Squid Game Token (2021) โ The โRug Pullโ Scam
Taking advantage of the global popularity of Netflixโs hit series Squid Game, developers launched the Squid Game Token (SQUID), claiming it would be used for a play-to-earn gaming platform. Investors rushed in, and within days, the tokenโs value skyrocketed from a few cents to over $2,800.
However, the project had red flags from the startโsuch as a lack of a legitimate development team and no real utility. Soon after the token peaked, the developers performed a โrug pullโ, draining liquidity from the project and disappearing with an estimated $3.3 million. The tokenโs price plummeted to nearly zero within minutes, leaving investors with worthless holdings.
6. Africrypt (2021) โ South Africaโs Largest Crypto Scam
In one of Africaโs biggest crypto scams, Africrypt, a South African investment firm run by two brothers, Raees and Ameer Cajee, vanished with $3.6 billion in Bitcoin. The company initially promised high returns and attracted thousands of investors.
In April 2021, Africrypt claimed it had been hacked and urged investors not to contact authorities, raising immediate suspicion. Soon after, the brothers disappeared, taking billions in Bitcoin with them. Despite legal efforts to trace the funds, most of the stolen assets remain unaccounted for.
Lessons Learned from Crypto Scams
These scams have had a profound impact on the cryptocurrency industry, leading to increased regulatory scrutiny, improved security measures, and greater investor awareness. Here are some key takeaways:
- Be Wary of Unrealistic Promises โ If an investment promises guaranteed high returns with little or no risk, itโs likely a scam.
- Verify the Team Behind the Project โ Ensure that the developers and founders have a verifiable track record in the industry.
- Use Reputable Exchanges โ Always trade and store crypto on well-established, regulated platforms with strong security features.
- Beware of Ponzi and Pyramid Schemes โ Any project that requires recruiting new investors to generate returns is a red flag.
- Conduct Thorough Research โ Before investing in any cryptocurrency or project, conduct extensive research and read independent reviews.
Conclusion
While cryptocurrencies have the potential to revolutionize the financial industry, they have also provided opportunities for scammers to exploit unsuspecting investors. By learning from past scams and staying vigilant, investors can protect themselves from falling victim to fraudulent schemes. As the industry matures, continued advancements in security, regulation, and investor education will play a crucial role in making the cryptocurrency space safer for everyone.
