These Ponzi Schemes Involve Millions of Stolen Dollars and Fraudulent CEOs

Most people dream of achieving financial freedom, whether that means traveling the world, retiring early, giving back through charity, or simply living without debt. While many pursue these goals through hard work, disciplined saving, and long-term investments, others take riskier routes. Regardless of the path, success often depends on trust, especially in the people and platforms managing your money.

That trust was severely shaken by the rise and fall of cryptocurrency exchange FTX, led by former billionaire Sam Bankman-Fried. Once hailed as a crypto visionary, Bankman-Fried was convicted of misusing billions in customer funds and was sentenced to 25 years in prison in March 2024. He joins the ranks of con artists, Ponzi schemers, corrupt CEOs, and rogue traders who betrayed the very investors and institutions they promised to serve. But who else is among these ranks?

To compile this list of the most infamous white-collar criminals in history, 24/7 Tempo reviewed reports and research from King University, Investopedia, Yahoo Finance, and additional financial crime databases. Selections were based on the size of the financial impact, global notoriety, and lasting cultural or legal consequences.

• Crime: Defrauding investors out of about $20 million
• Date of crime: 1919

The original "Ponzi scheme" involved luring investors with the promise of doubling their money within 90 days through the arbitrage of international reply coupons – vouchers accepted by multiple countries that can be converted into local postage stamps. Instead of trading IRCs, Ponzi used new investors to fund returns to older ones while seeking legitimate investments, like the purchase of a macaroni company, to keep the scam rolling.

Ponzi's scheme eventually cost investors $20 million (a quarter billion dollars today) and would have required 160 million IRCs when there were only 30,000 in circulation. Ponzi served 42 months in prison for the scam. After a second prison sentence, Ponzi was deported back to his home country of Italy where he died in poverty.

• Crime: Insider trading and stock manipulation
• Date of crime: 1980s

New York-based global investment bank Drexel Burnham Lambert saw Milken as head of the high-yield bond department until the company went belly up in 1990 (due to Milken's illegal activities). High-yield bonds are also called "junk bonds" because they have a very high risk of default but pay higher yields to attract investors.

Milken was outed by a colleague for his illegal transactions and was sentenced to 10 years in prison for securities fraud in 1989. He served about two years before being released, and in 2020, at the urging of conservative media mogul Rupert Murdoch, current House Majority Leader Kevin McCarthy, and other high-profile conservatives, he was pardoned by President Donald Trump.

• Crime: Insider trading
• Date of crime: Mid- 1980s

Boesky was known as "Ivan the Terrible" at the peak of his career. He was one of the country's wealthiest stock traders in the late '70s – until his arrest in 1986 for insider trading. Boesky epitomized the free-wheeling "greed is good" excesses of Wall Street in the 1980s, and partially inspired the character of Gordon Gekko in the 1987 Oliver Stone film "Wall Street."

He served two years in prison, paid a $100 million penalty to the Securities and Exchange Commission, and was banned from the financial services industry for his actions. His light sentence came after he agreed to help convict his associate, junk bond trader Michael Milken. Boesky is reportedly living a private life in California after winning $20 million in a divorce settlement.

• Crime: Stole retirement savings from investors, embezzled $200 million from insurance companies
• Date of crime: 1980s-1990s

Frankel was a discredited Toledo stockbroker who moved to Connecticut in the 1990s to become a brazen swindler, stealing more than $200 million from a network of small Southern insurance companies to fund his extravagant lifestyle at his Greenwich estate. When the law began to catch up with him, he lit his mansion on fire to destroy evidence and fled the country with $10 million worth of diamonds and two girlfriends on a chartered flight to Rome.

He was apprehended months later, in September 1999, in Hamburg, Germany, where he was jailed for passport fraud. He was then extradited to the U.S., where he was found guilty of embezzling money from 11 insurers he'd acquired through aliases and shell corporations. Frankel served more than 16 years in prison but returned to custody twice for parole violations.

• Crime: Stock market manipulation and running of a long-term scam involving penny stocks
• Date of crime: 1990s

Belfort served 22 months in prison for a massive pump-and-dump scheme involving risky penny stocks and misleading statements used to lure unwitting investors to his Long Island brokerage firm Stratton Oakmont, which employed hundreds of traders until securities regulators shut it down in 1996. (He was played by Leonardo DiCaprio in the 2013 Martin Scorsese film "The Wolf of Wall Street.")

In 2003, Belfort was ordered to pay $110 million in restitution, but by 2018 he had only forked out about $13 million. Belfort's net worth is a matter of speculation, but he makes significant money from his memoirs (including proceeds from the film adaptation of his first book) and motivational speaking engagements.

• Crime: Hundreds of people defrauded out of life savings
• Date of crime: 1991-1995

Many people are now subjected to constant streams of fraudulent robocalls aimed at gathering enough details about them to enable the callers to commit identity theft and wire fraud. But the heyday of U.S. telemarketing scams took place in the 1990s when scammers would use different methods to obtain bank information, enabling them to steal the life savings of their targets – especially the elderly, who were perceived to be more gullible.

The scams included posing as charity fundraisers; claiming the target had won a prize but needed to pay a fee; or even targeting previous fraud victims who were told they could recover their money, also for a fee. The FBI cracked down on these scams in the 1990s, including Operation Senior Sentinel, which led to about 1,200 arrests and hundreds of convictions.

(now operating as Encompass Health Corp.) was put on trial in the early 2000s for conspiracy, securities fraud, wire fraud, and money laundering. Prosecutors said Scrushy directed underlings at the company to commit $2.7 billion worth of accounting fraud in financial reports from 1996 to 2002.

However, in 2005, he was acquitted of all charges in an outlandish defense that convinced a jury. In 2007 he was convicted in another federal trial for bribery, conspiracy, and mail fraud, and was sentenced to nearly seven years in prison. In 2020, Scrushy's high-profile case was featured in the Netflix documentary series "Trial by Media."

Madoff was the man behind the biggest financial fraud crime in U.S. history who defrauded thousands of people and institutions out of billions of dollars over decades through his sham Wall Street firm Madoff Investment Securities. His strategy was to exude an air of exclusivity to exploit the fear of missing out on his high-value targets, which included celebrities like Kevin Bacon, Krya Sedgewick, Steven Spielberg, and Larry King, as well as banks, colleges, churches, and charitable organizations.

As early as 2003, a whistleblower exposed Madoff's scheme but it wasn't until the economic crash of 2009 that investigators began to look into his massive ruse. In 2021, Madoff died in prison while serving a 150-year sentence.

• Crime: Risky bets sank his company

In 1995, Japan's Kobe earthquake illustrated how a natural disaster can destroy a bank when one of its derivatives traders goes rogue. Trader Nick Leeson, a rising young star derivatives trader at the bank's Singapore-based futures operations worked for Barings Bank, then the U.K.'s oldest merchant bank. But his performance was a ruse to cover his failures.

He hid his losses and kept doubling down to recover them, including a fateful bet on the performance of the NIKKEI stock market right before the earthquake sent markets plummeting.By the time he was caught, his losses had grown to $1.4 billion, sending the 230-year-old bank into insolvency. After serving a six-and-a-half-year prison sentence, Leeson obtained a psychology degree, got married, and now spends his time on the speaking circuit.

Waksal was arrested and charged with insider trading after he informed family and friends of the impending FDA decision that had yet to be made public.

Waksal paid $4.3 million and served 87 months in prison before being released in February 2009.Among the people found to have benefitted from the insider trading was family friend Martha Stewart, who sold her ImClone shares days before the FDA announcement.

Even before he became a crooked preacher, Minkow was conning investors through their carpet cleaning and restoration company, ZZZZ Best, which was a front for numerous criminal financial acts. Minkow and an associate created a separate fake appraisal company to commit fraud through insurance claims adjustments.

While serving a 25-year sentence beginning in 1989 for these offenses, Minkow earned a master's degree in divinity from Virginia's Liberty University.After his early release from prison in 1995, the newly minted minister began defrauding churchgoers and using his anti-fraud business to short stocks in companies he was investigating – for which he was sentenced to another five years in prison in 2014.

Minkow later went on a reputation-rebuilding journey, in his case with the docuseries "King of the Con," which premiered last year on Discovery+.

Enron, the Houston-based energy and commodities firm that was one of the largest U.S. companies of the time, caused one of the most high-profile accounting scandals in U.S. history. At the center of one of the biggest frauds to occur during the irrational exuberance of the 90s dot-com era were company founder Kenneth Lay and C-suite executive Jeffrey Skilling.

They and other top executives deceived regulators using fake holdings and illegal accounting practices to hide Enron's mountain of debt and toxic assets from investors and creditors.In 2006, 64-year-old Lay died from a heart attack while vacationing in Aspen ahead of his sentencing. In 2019, Skilling was released early from a 24-year sentence and in 2021 established an energy trading company that has since become inactive.

After his release, he attempted to claim an $18 million tax refund on the $44 million he was ordered to pay in forfeiture for his crime. In 2017 the U.S. Supreme Court declined to hear Nacchio's appeal of a lower court's decision that he was not entitled to the refund.

While being investigated in 2009, Mizrahi fled to Israel, and Greenes followed his business partner there in 2012. A warrant for their arrest was issued in 2012, and the two men were arrested and extradited to the United States in 2021 to face trial.

Israel is currently serving a 22-year sentence for defrauding investors of more than $450 million from 1996 to 2005. Instead of reporting to prison in June 2008, Israel made a sloppy attempt to fake his suicide by parking his SUV on a bridge near New York City and leaving a message scrawled in dust on the hood of the vehicle that said "Suicide is painless," a reference to the title song in the 1970 Robert Altman film and the famous CBS television series "M*A*S*H."

Israel turned himself in at the urging of his mother and is serving time in the same prison that held another notorious Ponzi schemer, the late Bernie Madoff.In 2019, the Connecticut-based former hedge fund manager lost a bid for early compassionate release from prison based on his deteriorating health condition.

• Date of crime: 2011-2016

Company employees faced intense pressure from their managers to meet high sales quotas for lines of credit and savings accounts, which are more profitable to banks than checking accounts.

In desperate bids to meet unachievable goals and earn bonuses, salespeople opened fake accounts in the name of real customers. In 2020, the bank agreed to pay $3 billion to resolve its criminal and civil liabilities and in 2022 said it was still working to comply with a raft of government consent orders to clean up its act.

His crime included hacking into the bank's computer systems, fabricating positions, and executing about 1,000 illegal trades using about $1.4 billion worth of bank assets.

By the time Kerviel was arrested, he had cost the bank more than $7 billion. Kerviel's actions helped to expose the weak risk management in the global banking system that perpetuated the worldwide economic crash.

• Crime: Looting billions of dollars from the now-bankrupt FTX exchange
• Date of crime: 2019-2022

The 30-year-old founder of the failed cryptocurrency exchange FTX can be credited as the person responsible for exposing the problems with a loosely regulated, decentralized form of stored value.The MIT alum was arrested in the Bahamas in December 2022 after he was indicted on numerous federal charges for diverting customers' funds from FTX to his crypto-trading hedge fund Alameda Research.

FTX, which was one of the most well-respected cryptocurrencies on the market, faced a liquidity crunch and fell into bankruptcy, cutting off at least a million depositors from their accounts. Cryptocurrency detractors point to the fact that digital currency is subjected to wild swings in value, making it an unreliable form of payment for most transactions.

• Crime: Overbilling Native American casino owners
• Date of crime: Early 2000s

The disgraceful lobbyist and symbol of sketchy Washington influence-peddling was sent back to prison in 2020, becoming the first person charged under the Lobbying Disclosure Act after it was amended in 2007 in response to Abramoff's previous lobbying activities. This time, he pled guilty to criminal conspiracy to commit wire fraud for hiding his work on behalf of cryptocurrency and cannabis-related interests without registering as a lobbyist.

Abramoff had previously served nearly four years for bilking Native American tribes out of tens of millions of dollars in their effort to develop casinos on their reservations. Some of the money was used to purchase favors from federal lawmakers.
