It always begins with trust.
A flashy ad. A celebrity endorsement. A promise that this time, you’ve found the ticket to financial freedom. And then—silence. Funds gone. Accounts frozen. Support emails are unanswered.
That’s the terrible machinery of crypto fraud.
The past decade has been a graveyard of shattered promises and stolen billions. Some scams were slick, wrapped in high-end marketing and political influence. Others were crude but devastating—Ponzi schemes dressed in digital clothing. Together, they form a chilling tapestry of betrayal.
This is the Top 10 Crypto Scams, where ordinary people lost everything while fraudsters lived in luxury.
1. FTX Collapse – $8 Billion Vanished Overnight
The most infamous crypto scandal of all.
Sam Bankman-Fried, once hailed as a genius, secretly funneled $8 billion of customer funds from FTX to his trading firm, Alameda Research. The backdoor in FTX’s code let Alameda withdraw unlimited funds, while customers believed their assets were safe.
When withdrawals froze in November 2022, millions were locked out of their life savings. In 2024, SBF was sentenced to 25 years in prison.
Villain’s excesses: $40 million penthouse, private jets, political donations.
Victim’s suffering: retirees testifying, “I’m 67 and starting over with nothing.”
2. OneCoin – The Billion-Dollar “Crypto” That Never Existed
Dr. Ruja Ignatova, the “Cryptoqueen,” promised investors the next Bitcoin. The catch? There was no blockchain. No real coin.
Between 2014 and 2017, OneCoin stole over $4 billion from investors worldwide. Court filings revealed classic Ponzi mechanics: new investor funds paid off old ones.
Ignatova vanished in 2017 and remains on the FBI’s Most Wanted list. Victims across Europe and Asia were left holding worthless “coins” that never existed.

3. Mt. Gox Collapse – The First Crypto Horror
Before FTX, there was Mt. Gox, once the world’s largest Bitcoin exchange. In 2014, it declared bankruptcy after losing 850,000 BTC (worth over $450 million at the time).
Hackers siphoned coins for years, undetected due to weak controls. The exchange’s CEO faced trial in Japan. For many early investors, it was their first brutal lesson: in crypto, your money can vanish overnight.
4. BitConnect – The Infamous Ponzi Token
“Guaranteed daily returns.” Those three words lured thousands into BitConnect, a lending platform that promised profits from a secret trading bot.
In reality, it was a classic Ponzi scheme. New deposits paid off old investors until the system collapsed in 2018, wiping out billions in value.
Court records show leaders spent investor money on luxury cars and real estate. One victim testified: “It destroyed my family’s savings. We believed them.”
5. Celsius Network – The “Safe” Lender That Wasn’t
Marketed as a safe place to earn yield, Celsius Network encouraged users to deposit crypto for interest. But behind the scenes, executives were making reckless bets with customer money.
When crypto markets crashed in 2022, Celsius froze withdrawals. Hundreds of thousands of customers couldn’t access funds, with losses in the billions. Bankruptcy filings revealed executives withdrew their own funds before shutting the doors.
The nightmare twist: customers were considered unsecured creditors, meaning they may never see full recovery.
6. Terra/Luna Collapse – The Algorithmic Stablecoin That Wasn’t Stable
Do Kwon’s TerraUSD (UST) was supposed to be a stablecoin, pegged to the dollar through an “algorithmic” system involving Luna tokens.
But in May 2022, the algorithm broke. $40 billion in value evaporated in days. Investors described the collapse as “financial suicide fuel,” with reports of lives lost.
Kwon was later arrested in Montenegro after months on the run.
7. PlusToken – The Asian Mega-Ponzi
From 2018 to 2019, PlusToken promised high returns to investors in China, South Korea, and beyond. Authorities later revealed it was a multi-level marketing Ponzi scheme that stole more than $2 billion in crypto.
The scam’s leaders were arrested, but billions remain missing. Chain analysis showed stolen coins being laundered through mixers, haunting markets for years.
8. QuadrigaCX – The Exchange That Died with Its Founder
In 2019, Canadian exchange QuadrigaCX announced its CEO, Gerald Cotten, had died suddenly in India. Along with him? The private keys to $190 million in customer funds.
Later investigations suggested mismanagement, and Cotten had been using customer funds to cover trading losses long before his death. To this day, victims debate whether he faked his death or left them trapped in one of crypto’s strangest mysteries.
9. Thodex – The Turkish Exit Scam
In April 2021, Turkish exchange Thodex abruptly halted trading. Its founder fled the country, leaving 400,000 users without access to $2 billion in crypto.
The founder was eventually extradited and sentenced to over 11,000 years in prison under Turkish law. Justice was symbolic, but the money? Mostly gone.
10. Mining Investment Scams – The Ongoing Horror
Beyond headline cases, countless investors still fall for crypto mining scams. These schemes promise huge returns from cloud mining contracts. In reality, many are simple frauds—collecting deposits, showing fake dashboards, then disappearing.
The FTC reported tens of thousands of complaints about such scams in the U.S. alone, with billions lost since 2021.
Justice Delivered, But Damage Done
Across these scams, the pattern repeats: flashy promises, hidden fraud, devastating losses. Yes, many perpetrators faced prison—Bankman-Fried, BitConnect leaders, Do Kwon, Thodex’s founder. But justice doesn’t restore stolen retirement funds or heal the trauma victims carry.
One victim of Celsius put it bluntly: “I trusted them more than my bank. Now I can’t pay my mortgage.”
How to Avoid Becoming the Next Victim
Here are red flags straight from government cases:
-
Guaranteed returns → Always a scam.
-
Celebrity endorsements without transparency.
-
No proof of reserves or audited financials.
-
Offshore registrations in weakly regulated jurisdictions.
-
Pressure to recruit others for bonuses (a Ponzi hallmark).
If it sounds too good to be true, it probably is.
The Horror Epilogue: Lasting Consequences
The Top 10 Crypto Scams left a trail of broken trust. Billions stolen. Families devastated. Lives derailed. Regulators worldwide are cracking down harder than ever, pushing for stricter oversight and investor protections.
But here’s the cruel truth: fraudsters adapt. The next scheme may already be underway.
Conclusion
Crypto promised freedom from banks. For many, it delivered something darker: nightmares disguised as opportunities.
From FTX’s $8 billion fraud to OneCoin’s phantom blockchain, the lesson is the same. Don’t trust hype. Don’t trust promises. Trust proof.
Your money deserves safety. And in the world of crypto, safety means skepticism.
