The Antoine Marsan Pump-and-Dump Scheme: How a Crypto Fraud Led to Murder in Canada

The cryptocurrency industry has become synonymous with innovation, yet cases like that involving Antoine Marsan and Kevin Mirshahi reveal the dark underbelly of digital asset promotion. In 2024, a chain of events unfolded that would transform a financial fraud into a criminal tragedy, highlighting how unchecked crypto schemes can spiral into violence. The story begins not with kidnapping but with a carefully orchestrated token manipulation scheme that victimized thousands of young Canadians.

How Antoine Marsan and Bastien Francoeur Created a Market Manipulation Scheme

In April 2021, Antoine Marsan and Bastien Francoeur launched Marsan Exchange and released a token called Marsan ($MRS). The project appeared legitimate on the surface, but within days, the reality became clear: this was a textbook pump-and-dump operation. The token launched on April 14, 2021, and skyrocketed to CAD $5.14 ($3.67 USD) within just three days. However, this explosive growth was artificial. On April 18, 2021, just four days after launch, major token holders cashed out en masse, causing the price to collapse to $0.39—a 92% loss in value.

The scheme targeted primarily young investors, with approximately 2,300 members losing substantial sums. Notably, many victims were between 16 and 20 years old, making them particularly vulnerable. Antoine Marsan’s company profited by creating artificial scarcity and demand, then dumping their holdings when retail investors (mostly teenagers) had bought in at peak prices.

Kevin Mirshahi: The Promoter Who Refused to Stop Despite Regulatory Warnings

Kevin Mirshahi, a 25-year-old crypto entrepreneur, played a crucial role in promoting the Marsan token. He received compensation in the form of the token itself, incentivizing him to recruit more participants through his Telegram group, “Crypto Paradise Island,” which served as a hub for investment discussions. As the scheme unraveled and regulators began investigating, Mirshahi’s activities should have ceased—but they didn’t.

Quebec’s financial watchdog, the Autorité des marchés financiers (AMF), opened an investigation into the Marsan Exchange and related activities in 2021. Mirshahi and his company faced serious sanctions: they were banned from acting as brokers or investment advisers, prohibited from conducting securities transactions, and ordered to remove all social media content and delete any references to the AMF. Despite these explicit prohibitions, Mirshahi defiantly continued operating a Telegram group called “Amir” to promote cryptocurrency investments to the public.

From Regulatory Evasion to Murder: The Tragic End

Mirshahi’s defiance of regulatory authority had consequences far beyond financial penalties. On June 21, 2024—nearly three years after the initial pump-and-dump—Mirshahi and three others were kidnapped from a Montreal condo parking garage. The following day, three of the four abductees were discovered alive in western Montreal. But Mirshahi remained missing. By August 2024, authorities had determined that he had been murdered. His body was found on October 30, 2024, at Île-de-la-Visitation park.

While the exact circumstances of his death remain under investigation, the timeline raises troubling questions: Did victims of the Marsan scheme seek revenge? Did Mirshahi’s continued evasion of regulatory authority make him a target? The AMF’s apparent inability to stop Mirshahi’s illegal activities before his death suggests serious gaps in regulatory enforcement capabilities.

A Broader Pattern: Cryptocurrency Crimes Are Escalating Across Canada

The Mirshahi case is not an isolated incident. Canada has witnessed a sharp rise in cryptocurrency-linked crimes, including kidnappings, extortion, and violence. These incidents reflect a growing tension between a largely unregulated crypto ecosystem and those who exploit it for personal gain. The fact that someone like Antoine Marsan could launch a fraudulent scheme that resulted in hundreds of thousands of dollars in losses to young Canadians, with regulatory bodies struggling to enforce compliance, exposes a critical vulnerability.

The Antoine Marsan Marsan token case and its aftermath serve as a grim reminder: cryptocurrency fraud can have consequences that extend far beyond financial loss. When regulatory systems fail to stop bad actors, violence may follow.
