ToggleThe Beginnings of Isabelle Mercier
Isabelle Mercier was born on August 5, 1975, in Victoriaville, Québec (Canada). From a young age, she showed interest in poker, learning her first strategies during family gatherings. However, her professional path began in the legal field, as she studied law at the University of Montreal and briefly practiced as a commercial law attorney.
Her time in the legal world was short but meaningful. She soon realized her true calling lay elsewhere, prompting her to move to Paris, where she earned a master’s degree while working as a room manager at the prestigious Aviation Club de France (ACF). It was during these five years—described by her as “fabulous”—that her mentor Bruno Fitoussi, the man who introduced poker to France, became one of her closest friends and main influences. This role allowed her to combine her organizational skills with her growing passion for poker, serving as a springboard into her professional playing career. Her talent and dedication at the ACF were so notable that she was twice nominated for “Staff Member of the Year” at the European Poker Awards. This phase was fundamental, as it gave her a comprehensive understanding of the poker business—especially from the other side of the table—a perspective that would later prove invaluable in the creation of CoinPoker.
“No Mercy”: A Career Defined by Strategy
The nickname “No Mercy” is no coincidence. Isabelle earned it through her aggressive, calculated, and uncompromising playing style. As she moved into international tournaments such as the World Poker Tour (WPT) and the European Poker Tour (EPT), her standing as a respected figure in the professional circuit was cemented. Although she never won a World Series of Poker (WSOP) bracelet, Isabelle accumulated multiple prizes and a reputation as a meticulous strategist.
Her largest live tournament prize was $341,862, and her total earnings exceed one million dollars. But beyond the numbers, what sets Isabelle apart is her cerebral approach to the game. For her, poker is not just about luck or intuition—it’s a discipline that demands preparation, psychological insight, and emotional control.
The Crypto World and the Founding of CoinPoker
Isabelle Mercier’s drive didn’t stop at traditional poker. In 2017, she became an ambassador for CoinPoker, a then-emerging online poker platform based on blockchain technology. Her role went beyond being the public face; Isabelle Mercier is a co-founder of CoinPoker alongside fellow professional player and entrepreneur Tony G. CoinPoker was conceptualized by a group of crypto and poker enthusiasts who aimed to create a more transparent, secure, and decentralized alternative to established online poker rooms. The platform’s use of blockchain technology seeks to address common challenges in online poker, focusing on transparency of transactions and fairness of gameplay. Mercier and Tony G shared a clear goal: to create “a fair, fast, and accessible poker room for everyone.”
As co-founder, Mercier’s meticulous approach and experience have been key in designing the user experience, tournament structure, and building a strong community around the platform. Her transition into the crypto world was partly influenced by Tony G, whom she describes as “a man of vision” and credits for helping her become an early adopter of cryptocurrencies.

Isabelle contributed her expertise as both player and manager, helping to design a user-friendly, fair, and community-oriented interface. CoinPoker uses its own cryptocurrency (CHP) and allows deposits and withdrawals in USDT, ETH, and BTC, eliminating intermediaries and reducing costs. Most notably, the platform’s integration of blockchain-backed randomness and direct, borderless financial transactions illustrates CoinPoker’s intention to challenge the limitations of traditional online poker rooms. These aspects reinforce user trust and signal a shift in how online poker platforms can be constructed and managed.
At CoinPoker, Isabelle has managed to integrate all her facets: player, manager, and educator. Continuing her passion for poker, she actively participates on the platform, playing tournaments and one of her favorite formats, Open Face Chinese Poker (OFC), for which she even hosts a weekly bounty tournament. She also contributes content, sharing her knowledge and experiences through articles and posts that offer an intimate view of poker and pay tribute to the figures who inspired her.
Passions and Personal Projects
Isabelle Mercier’s creative energy extends beyond poker tables and boardrooms. Expanding her interests, she has cultivated a unique and diverse identity. Mercier is the creator of her own handmade jewelry line. Under the name “No Mercy Making,” she offers a poker-themed collection called “All-in,” featuring unique, handcrafted pieces that reflect her style and passion for the game.
In 2008, she published her autobiography, “Profession: Bluffeuse” (Profession: Bluffer), where she recounts the adventures of a woman traveling the world in pursuit of her dream to live off poker. The book, a testament to her life and career, is available in French and Italian. Her dedication to Open Face Chinese Poker (OFC) is such that in 2015 she won the first Progressive OFC World Championship in Prague, establishing herself as one of the top players in this discipline.
