Giancarlo Devasini is an Italian businessman, the self-made billionaire Chief Financial Officer (CFO) of Bitfinex (a major crypto exchange) and the co-founder of Tether (USDT), the world's largest stablecoin. His career is one of extreme pivots: he completed his medical studies at the University of Milan in 1990 and began his career as a plastic surgeon.

Devasini soon left medicine, recognizing his calling in technology and finance. In 1992, he founded his first company, importing computer components from Asia. After selling his successful hardware business, he accidentally discovered Bitcoin in 2012. Recognizing its massive potential, he partnered with others to found Bitfinex in 2012. This unique journey—from plastic surgeon to hardware mogul to crypto titan—defines his immense fortune.

Giancarlo Devasini officially became Bitfinex's CFO in 2013. His most significant strategic move was co-founding Tether (USDT) in 2014. Tether's innovation was the creation of the US dollar-pegged stablecoin, designed to bridge the gap between the traditional financial system and the volatile crypto world. USDT quickly became the largest stablecoin by market capitalization and a crucial component of global crypto liquidity.

His career is marked by controversies over Tether's backing, possible market manipulation, and high-profile legal scrutiny from U.S. and international regulators. Despite this, his immense wealth (estimated at $22.4 billion in 2025) is secured by his large stake (47 percent) in Tether. He maintains a notoriously low profile, running his multi-billion dollar business from a discreet office above a sports bar in Lugano, Switzerland, and actively promoting cryptocurrencies and blockchain technology through partnerships with the city of Lugano.

Giancarlo Devasini's social impact is structural, stemming from Tether's role in providing the bedrock of liquidity for the entire global cryptocurrency market. The stablecoin is a crucial infrastructure component for the multi-trillion dollar crypto economy.

His personal philanthropy supports various community and educational initiatives, often tied to promoting blockchain technology and financial innovation. His career provides a compelling narrative of a serial entrepreneur who successfully adapted to multiple industry transitions, culminating in dominance over the most influential product in the crypto space.

Giancarlo Devasini maintains the professional, yet highly discreet, style of a crypto mogul. His attire is consistently formal and high-quality, favoring tailored business suits. His aesthetic is one of stability and commanding competence, reflecting his deep involvement in finance and technology, often contrasting with the low-profile office location above a sports bar in Lugano.

Residing in Lugano, Switzerland, his luxury is the immense security and financial power derived from his multi-billion dollar fortune. His life is dedicated to digital finance innovation, strategic market control, and navigating the complex regulatory challenges of the crypto world.
