These real-life incidents highlight the risks—and why $MASTR is here to protect investors with tools, alerts, and insurance.
Here’s a look some of the biggest #crypto #scams, by $MASTR
1. OneCoin ($4B Ponzi Scheme)
- Details: Marketed as the "Bitcoin killer," OneCoin claimed to have a unique blockchain and promised huge returns. In reality, there was no blockchain or transparency. It targeted investors worldwide through aggressive marketing and multi-level marketing schemes. Ruja Ignatova, known as the "Cryptoqueen," disappeared in 2017, evading law enforcement. The scam affected over 3 million victims globally.
- Impact: One of the largest financial scams in history, eroding trust in cryptocurrency.
- $MASTR Solution: Scam alerts and pre-investment checks help identify fraudulent projects before investors commit funds.
2. Squid Game Coin ($3.3M Rug Pull)
- Details: Using the popularity of Netflix's "Squid Game," developers created a token that surged in value due to hype and limited withdrawals. Investors were lured with promises of a play-to-earn game. When the value peaked, developers pulled the liquidity and disappeared.
- Impact: A classic pump-and-dump scheme that preyed on cultural trends and investor FOMO (Fear of Missing Out).
- $MASTR Solution: Early detection of suspicious projects and insurance options provide a safety net for investors.
3. Thodex ($2B Exchange Exit Scam)
- Details: Thodex, a Turkish crypto exchange, offered promotions like luxury cars to attract investors. In 2021, it abruptly froze withdrawals, claiming technical issues, and its CEO fled the country with $2 billion in user funds. Victims ranged from small retail investors to large-scale traders.
- Impact: Highlighted the lack of regulatory oversight in crypto exchanges.
- $MASTR Solution: Promote due diligence, transparency, and provide insurance for exchange-related assets.
4. Bitconnect ($3.4B Ponzi Scheme)
- Details: Bitconnect claimed to use an automated trading bot to generate 40% monthly returns. Investors were paid with funds from new participants, making it a classic Ponzi scheme. It collapsed in 2018, leaving thousands of investors with massive losses.
- Impact: Damaged the reputation of legitimate cryptocurrency projects and increased regulatory scrutiny.
- $MASTR Solution: Education on unrealistic return promises and tools to conduct due diligence on investment opportunities.
5. Mt. Gox ($450M Exchange Hack)
- Details: As the world’s largest Bitcoin exchange at the time, Mt. Gox handled 70% of all Bitcoin transactions. In 2014, hackers exploited vulnerabilities, stealing 850,000 BTC, worth $450 million then and billions today. Victims waited years for partial reimbursements.
- Impact: A wake-up call for the importance of exchange security in the crypto industry.
- $MASTR Solution: Advocate for secure platforms, regular audits, and insurance coverage to protect against similar hacks.
6. PlusToken ($2B Ponzi Scheme)
- Details: Marketed as a wallet and investment scheme, PlusToken promised users unrealistically high returns from "crypto arbitrage." In 2019, the scheme collapsed when developers disappeared, leaving behind a $2 billion void.
- Impact: Millions of victims, primarily in Asia, were left with significant financial losses.
- $MASTR Solution: Pre-investment analysis and scam alerts to identify and avoid high-risk schemes.
7. CryptoZoo ($7.7M NFT Fraud)

- Impact: Exposed the risks of influencer-backed projects without accountability.
- $MASTR Solution: Tools to verify project legitimacy and assess the reliability of the development team.
8. Terra/LUNA Collapse ($60B Market Crash)
- Details: Terra’s algorithmic stablecoin (UST) and its native token, LUNA, were designed to maintain a peg through a burn-and-mint mechanism. When market pressure destabilized UST, LUNA's value collapsed, wiping out $60 billion in market value and destroying investor confidence.
- Impact: Triggered widespread panic, affecting both retail and institutional investors.
- $MASTR Solution: Insurance coverage to mitigate losses and tools to assess risk in algorithmic systems.
9. SaveTheKids Token ($Multi-Million Rug Pull)

- Impact: Damaged public trust in charity-focused crypto projects and influencer-backed campaigns.
- $MASTR Solution: Monitor and expose pump-and-dump schemes, particularly those promoted by influencers.
10. FTX Collapse ($8B Fraud)
- Details: Once the second-largest crypto exchange, FTX collapsed in 2022 after it was revealed that customer funds were misused to cover losses in affiliated trading firm Alameda Research. The collapse wiped out $8 billion, leaving users and investors devastated.
