Wences Casares (born February 26, 1974) is an Argentine-born technology entrepreneur and investor widely credited with introducing Bitcoin to Silicon Valley's most influential executives, investors, and technologists. He is the founder and CEO of Xapo, a Bitcoin custodian and private bank, and has served on the boards of PayPal, Libra (now Diem), and other major technology and financial companies.
Casares occupies a singular role in Bitcoin history -- not as a developer or protocol contributor, but as the person who brought Bitcoin into the conversations of the world's most powerful investors and technologists. His personal story of growing up in a country with broken money gives his advocacy a particular authenticity that resonated deeply with his audience.
Early Life and Background
Casares was born and raised in Patagonia, Argentina, a background that profoundly shaped his understanding of money. Growing up in Argentina during the 1980s and 1990s, he experienced firsthand the devastating effects of hyperinflation, currency devaluations, bank freezes, and the wholesale confiscation of citizens' savings. He watched his parents lose their life savings multiple times -- not through bad decisions, but through the failure of the monetary system itself.
These formative experiences gave Casares an intuitive understanding of monetary fragility that most people in developed economies lack. When he later encountered Bitcoin, he recognized its properties immediately -- not as an abstract technological curiosity, but as a concrete solution to problems he had lived through.
Career Before Bitcoin
In the late 1990s, while still in his twenties, Casares founded Internet Argentina, which became Patagon -- Latin America's largest online brokerage and financial portal. The company expanded across Latin America and into Europe, offering online banking, brokerage services, and financial content.
In 2000, at the height of the dot-com boom, Banco Santander acquired Patagon for $750 million -- one of the largest internet acquisitions in Latin American history. This exit established Casares's reputation as a world-class fintech entrepreneur and gave him the credibility and network that would later prove essential to his Bitcoin evangelism.
After Patagon, Casares founded several additional companies including Lemon Wallet (acquired by LifeLock), Banco Lemon (a digital banking venture in Brazil), and Bling Nation (a mobile payments startup). Each venture deepened his expertise in payments, banking, and the intersection of technology and finance.
Bitcoin Evangelism
Casares discovered Bitcoin around 2011-2012 and quickly became convinced it represented the most important financial innovation of his lifetime. His conviction rested on two pillars: his technical understanding of Bitcoin's protocol and his personal experience with the failure modes of fiat currency systems.
Beginning in 2012-2013, Casares undertook what amounted to a systematic, personal campaign to introduce Bitcoin to the most influential people in technology and finance. He hosted intimate dinners -- often at his home -- where he would walk attendees through Bitcoin's properties, history, and significance. His guest lists included figures such as Reid Hoffman (co-founder of LinkedIn), Bill Gates, and numerous venture capitalists and hedge fund managers.
What made Casares uniquely effective was his credibility. He was not a cypherpunk, a libertarian ideologue, or a speculator. He was a proven fintech entrepreneur who had built and sold companies for hundreds of millions of dollars, who sat on the board of PayPal, and who spoke about Bitcoin in the measured language of someone who had spent decades thinking about money and technology. His role in Bitcoin's Silicon Valley adoption story is documented in Nathaniel Popper's Digital Gold.
Xapo
In 2013, Casares founded Xapo to address what he considered Bitcoin's most urgent practical problem: secure custody. Recognizing that most Bitcoin losses were due to poor key management rather than protocol flaws, he built an institutional-grade custody solution anchored by a cold storage vault inside a decommissioned Swiss military bunker in the Swiss Alps.
Xapo grew to become one of the largest Bitcoin custodians in the world. The company later obtained a banking license in Gibraltar and rebranded as Xapo Bank, offering a full-stack private banking experience that combines Bitcoin custody with traditional banking services.
Philosophy on Bitcoin
Casares is perhaps best known for his pragmatic, accessible framing of Bitcoin as an investment:
"I tell everyone: put 1% of your net worth in Bitcoin. If Bitcoin fails, 1% won't matter. If Bitcoin succeeds, you'll want to have been early."
This framing -- low-risk, high-optionality -- was specifically designed to resonate with the risk-averse mindset of traditional investors. He has also spoken extensively about Bitcoin's potential for financial inclusion, particularly for the billions of people worldwide who lack access to stable currencies and reliable banking systems.
Significance
Wences Casares's contribution to Bitcoin cannot be measured in lines of code or BIPs authored. His contribution was social and cultural: he took Bitcoin out of the cypherpunk forums and into the boardrooms of the world's most powerful companies. In the history of Bitcoin's adoption, the period from 2012 to 2015 -- when Silicon Valley's attitude shifted from dismissal to curiosity to investment -- bears Casares's fingerprints more than perhaps any other individual's.
