What Is Giancarlo Devasini’s Net Worth?
Giancarlo Devasini is an Italian entrepreneur, former plastic surgeon, and cryptocurrency executive whose estimated net worth is $55 billion, placing him among Italy’s wealthiest individuals.
He is chairman and controlling shareholder of Tether, the company behind USDT, the world’s leading dollar-backed stablecoin. Devasini was also instrumental in developing Bitfinex, one of the crypto sector’s longest-running major exchanges.
Devasini’s rise to the upper ranks of Italy’s rich list followed an unusual route. After training as a doctor and spending a short time in plastic surgery, he left medicine for the computer-hardware trade. Nearly 20 years of importing, selling, and redistributing electronic components preceded his discovery of Bitcoin in 2012 and his entry into Bitfinex a year later.
He later became the financial strategist behind both Bitfinex and Tether. For years, Devasini served as chief financial officer, built relationships with banks, and helped steer the businesses through cyberattacks, regulatory conflicts, and repeated difficulties accessing traditional financial institutions. He eventually became Tether’s largest shareholder.
Tether’s business model became highly profitable as demand for USDT surged. Customers exchange dollars for the tokens, while Tether invests much of the underlying reserve in income-generating assets, especially short-term U.S. government debt. The company reported more than $13 billion in profit during 2024 and over $10 billion in 2025. By 2026, USDT in circulation exceeded $180 billion.
Early Life
Giancarlo Devasini was born in Turin, Italy, in 1964. He studied medicine at the University of Milan and earned his Doctor of Medicine degree in 1990.
He began his professional life in plastic surgery, but remained in the field for only about two years. Devasini later said he grew uneasy with cosmetic procedures because he believed some patients did not genuinely require them.
In 1992, he walked away from medicine and moved into a field that had long captured his interest: computing.
Computer Hardware Business
Devasini established his first significant business in computer hardware in 1992, founding Point-G Srl in Milan. The company imported components from producers in China, Hong Kong, and Taiwan before distributing them across European markets.
As the semiconductor and personal-computer markets expanded, Devasini built a business around sourcing low-cost parts and reselling them in Europe. He founded Solo SpA in 1997, one of several companies he ran during his hardware career.
Solo specialized in part in DRAM memory. Instead of taking on major chipmakers directly, Devasini targeted memory batches that fell short of manufacturers’ initial specifications but could still be tested, sorted, graded, and marketed for alternative uses.
His business network later grew to include firms such as Compass, Alcosto, Freshbit, and Acme. Bitfinex subsequently characterized the hardware group as employing more than 100 people and producing €113 million in annual revenue. Other accounts drawing on Italian corporate records describe a less expansive final chapter, including a major warehouse fire in early 2008 and the eventual liquidation of Solo SpA.
Regardless of the group’s exact peak size, Devasini spent much of two decades sourcing, trading, financing, and transporting technology products across borders. That experience became a valuable foundation for his move into cryptocurrency, another globally connected industry that often faced serious challenges in dealing with conventional banks.
Discovering Bitcoin
After exiting the hardware sector, Devasini made a brief attempt at retirement. It soon ended after he discovered Bitcoin in 2012, when the digital-currency market was still in its infancy.
An early public indication of his involvement appeared on online crypto forums, where he offered CDs and DVDs in exchange for Bitcoin. At the time, the cryptocurrency traded at only a tiny fraction of its eventual value.
Devasini quickly came to see cryptocurrency as a potentially transformative business opportunity. Later in 2012, he met Raphael Nicolle, founder of the exchange that would become Bitfinex, and joined the venture as a partner in 2013.
Bitfinex
Bitfinex went on to become one of the defining exchanges of Bitcoin’s early years. Devasini’s role centered less on software development than on addressing the operational, funding, and banking hurdles that challenged young crypto companies.
He helped build the workforce, secure banking partners, attract capital, and shift operations across jurisdictions. Devasini ultimately took on the position of Bitfinex chief financial officer.
While Brian Armstrong’s Coinbase eventually became a publicly listed U.S. company, Bitfinex remained privately controlled and operated through a collection of entities outside the United States. Its parent company, iFinex, would later become deeply linked to Tether.
What Is Tether?
Tether began as a cryptocurrency venture called Realcoin, launched in 2014 by Brock Pierce, Reeve Collins, and Craig Sellars. The project aimed to pair cryptocurrency’s speed and portability with the relative stability of the U.S. dollar. Later that year, Realcoin was renamed Tether.
Bitcoin can rise or fall dramatically in a matter of hours, while a stablecoin attempts to solve that problem by maintaining a fixed value. Tether’s flagship product, USDT, is designed so that:
1 USDT = $1
A customer can provide dollars to Tether and receive an equivalent quantity of USDT tokens. Those tokens can then be transferred across blockchain networks, traded on cryptocurrency exchanges, or held as a digital representation of dollars.
For cryptocurrency traders, USDT provided a way to move in and out of volatile assets without constantly transferring money through banks. In countries with unstable currencies or limited access to U.S. banking, it also provided a way for people to hold and transfer a digital asset tied to the dollar. The idea proved enormously successful.
Pierce’s involvement with Tether ended during the project’s early years. As Tether became increasingly intertwined with Bitfinex, Devasini and the Bitfinex ownership group emerged as the people controlling and operating the company that would turn USDT into a global financial giant.
Devasini and Tether
Devasini was not one of Tether’s original founders, but he became one of the central figures behind the company as it grew. Tether and Bitfinex shared senior executives and ownership, with Devasini serving as chief financial officer of both businesses for years.
Although other executives became more publicly visible, Devasini developed a reputation inside the cryptocurrency industry as the key financial strategist behind the companies. He also became Tether’s controlling shareholder.
Because Tether remains privately held, its complete capitalization table is not publicly disclosed. Public reporting has placed Devasini’s ownership in the 40% to 47% range, making him by far the company’s largest individual shareholder.
For much of Tether’s history, Devasini avoided interviews and public appearances. Paolo Ardoino, who became Tether’s chief executive officer in 2023, increasingly served as the company’s public face while Devasini remained focused on strategy and finance.
In March 2025, Devasini stepped down as Tether’s chief financial officer and became chairman of the group. Simon McWilliams was appointed CFO.
How Tether Makes Money
Tether’s extraordinary profitability comes from what happens to the money customers exchange for USDT. If a customer provides Tether with $1 million in exchange for one million USDT tokens, Tether now controls $1 million that must remain available to support those tokens.
Rather than leaving all of that money sitting in non-interest-bearing bank accounts, Tether invests much of its reserves in highly liquid assets, especially U.S. Treasury securities and repurchase agreements backed by government debt. Tether keeps the investment income.
At sufficient scale, that is an extraordinary business. When tens of billions of USDT were outstanding, Tether controlled tens of billions of dollars of reserves. When circulation climbed past $100 billion, the interest generated by
