The world of cryptocurrency is no longer confined to tech-savvy developers and financial pioneers. Today, a growing number of high-profile personalities—from Hollywood actors and music legends to sports icons and public figures—are stepping into the blockchain space, lending their influence to digital assets and decentralized technologies. Their involvement not only boosts public awareness but also legitimizes the industry in the eyes of mainstream audiences.
This shift mirrors the rise of technology evangelists in the early days of personal computing—visionaries like Steve Jobs and Guy Kawasaki, who combined charisma with technical insight to drive adoption. Now, a new breed of influencers—crypto ambassadors—is doing the same for blockchain. While some bring deep expertise, others leverage fame to spotlight innovation, privacy, and financial inclusion.
Below, we explore 12 notable figures who have publicly supported or invested in cryptocurrency, shaping how millions perceive this transformative technology.
Ashton Kutcher: Hollywood’s Leading Crypto Advocate
Ashton Kutcher isn’t just a celebrity; he’s a seasoned tech investor. Long before crypto went mainstream, Kutcher backed key infrastructure projects like BitPay and BitGo, investing millions at an early stage. His venture capital firm, Sound Ventures, has consistently prioritized blockchain innovation.
“Bitcoin… is like the internet in the 1980s.” — Ashton Kutcher, 2014
Kutcher sees cryptocurrency as foundational infrastructure—comparable to early internet protocols—and believes mass adoption hinges on usability and trust. His advocacy extends beyond investment; he actively promotes education and real-world utility for digital currencies.

Jennifer Lopez: A Star Embracing Fintech Innovation
Jennifer Lopez made headlines when she became one of the first celebrities paid in Bitcoin for a performance—reportedly receiving 1,500 BTC, tax-free. But her involvement goes deeper than one-time payments.
In 2019, The Wall Street Journal revealed that Lopez joined Acorns Grow Inc., a fintech platform focused on micro-investing. Alongside figures like Bono and Kevin Durant, she supports initiatives that democratize wealth-building tools. There are even indications she may help design financial products tailored to women and young investors.
Her move reflects a broader trend: celebrities using their platforms to promote financial literacy and accessible investing.
Jerome Flynn: From Westeros to Vegan Crypto
Best known as Bronn in Game of Thrones, Jerome Flynn brings unexpected depth to the crypto world. As an animal rights activist and patron of The Vegan Society alongside Stella McCartney, his role as advisor to VeganNation—an Israeli blockchain project promoting cruelty-free commerce—feels natural.
VeganNation’s ecosystem allows users to earn and spend a native token while supporting ethical brands. Flynn’s endorsement highlights how blockchain can align with personal values like sustainability and transparency.
“To all my beloved Game of Thrones fans: I’m just as excited as you!” — Jerome Flynn, 2019
Ellen DeGeneres: Humor Meets Crypto Curiosity
Ellen DeGeneres used her massive platform to demystify Bitcoin during a 2019 episode of The Ellen Show. Joking that Bitcoin was “like a goat that doesn’t exist except on the internet,” she compared its value mechanism to stocks—while playfully preferring actual goats.
Ironically, later that year, Ashton Kutcher gifted her $4 million worth of Ripple (XRP) during a taping. The gesture underscored how crypto is becoming part of celebrity culture—not just as investment, but as currency for philanthropy and gifting.
Music Legends Rally Behind Monero
In 2017, Monero—a privacy-focused cryptocurrency—took a creative turn by launching the Reef Project, partnering with over 40 artists including Mariah Carey, G-Eazy, Sia, Slayer, and Fall Out Boy. These stars offered 15% discounts to fans who paid in Monero during the holiday season.
This campaign wasn’t about quick profits—it aimed to increase real-world usability of privacy coins and educate consumers about secure, anonymous transactions.
“Mariah Carey, G-Eazy, Sia among artists accepting Monero this holiday season.” — Forbes, 2017
Athletes Join TokenStars: Blockchain Meets Sports Management
Legendary athletes like Lothar Matthäus (Germany), Tommy Haas (Germany), Nikita Kucherov (NHL), and Martina Hingis (tennis) united under TokenStars, the first blockchain-based platform for managing celebrity sports talent.
Matthäus called it his “first and only blockchain project,” expressing eagerness to learn more about decentralized finance. The platform enables fans to invest in athletes’ careers through tokenized shares—a glimpse into the future of sports economics.
David Stern: NBA Legend Champions FanChain
David Stern, former NBA commissioner, serves as advisor to FanChain, a cryptocurrency aiming to revolutionize sports entertainment via decentralization. Joined by NFL player Vernon Davis and NBA legend Billy Owens, Stern acknowledges he doesn’t fully grasp crypto valuations—but chooses engagement over exclusion.
“I still struggle to understand why Bitcoin or Ethereum have such unbounded value.” — David Stern
Yet his participation signals institutional curiosity: if legacy sports leaders see potential in blockchain fan engagement, the industry’s credibility grows.
Ronaldinho: Building a Football Empire on Blockchain
Brazilian football icon Ronaldinho launched Ronaldinho Soccer Coin (RSC) to fund global football academies, amateur leagues, betting platforms, and virtual stadiums. His vision includes a blockchain-powered database analyzing player skills to form AI-curated teams.
This fusion of sport, gaming, and decentralized data could redefine athlete development and fan interaction.

Dennis Rodman: Controversial Promoter of PotCoin
Dennis Rodman stirred debate when he wore a PotCoin T-shirt during a diplomatic trip to North Korea alongside Donald Trump-era tensions. Sponsored by the cannabis-focused cryptocurrency, Rodman has long promoted PotCoin despite criticism over its speculative nature.
While controversial, his visibility brought national media attention—including coverage by CNN—highlighting how crypto marketing often walks the line between advocacy and hype.
Manny Pacquiao: The Senator-Turned-Crypto Creator
Boxing legend Manny Pacquiao took an innovative step by launching his own fan token, allowing supporters to buy merchandise and engage via social channels. Backed by investors like Michael Owen and Sheikh Khaled bin Zayed Al Nahyan, Pacquiao’s project blends fandom with utility.
More notably, as a sitting senator in the Philippines since 2016, he stands out as the most politically influential figure to launch a cryptocurrency, bridging governance and decentralized finance.
Floyd Mayweather & Steven Seagal: Cautionary Tales
Not all celebrity endorsements are trustworthy. Floyd Mayweather earned the nickname “Crypto Mayweather” for promoting multiple Initial Coin Offerings (ICOs), including Centra Tech, later exposed as a scam. He advertised a non-functional Centra debit card without disclosure—resulting in an SEC fine.
Steven Seagal similarly endorsed fraudulent ICOs tied to Russian-linked entities. These cases remind us: fame doesn’t equal credibility. Due diligence remains essential.
⚠️ Always research projects independently—celebrity backing isn’t a safety guarantee.
Nicolás Maduro: Nation-State Crypto Experimentation
Venezuelan President Nicolás Maduro launched Petro (PTR), a government-backed cryptocurrency allegedly tied to oil reserves. While criticized for evading sanctions rather than empowering citizens, Petro represents a bold—if controversial—step toward hybrid monetary systems.
José Angel Alvarez, head of Venezuela’s National Cryptocurrency Association, called it “a bold and correct decision” toward economic duality—fiat vs. digital.
Despite U.S. sanctions freezing Venezuelan assets, peer-to-peer crypto trading surged locally, proving demand for alternative financial tools amid crisis.
