Cryptocurrencies have evolved from a niche digital trend into a multi-trillion-dollar global industry. What began as an experiment in decentralized finance has now infiltrated nearly every corner of modern life—including sports betting, online retail, e-commerce, and digital content creation.

Platforms offering everything from megaways slots to streaming services have started integrating blockchain-based payment systems, signaling crypto’s widespread adoption. One of the industries most visibly influenced by this shift is entertainment. Celebrities—whether actors, musicians, athletes, influencers, or entrepreneurs—have increasingly gotten involved in the crypto space.

Some are investors like Ashton Kutcher who've put their own funds into Bitcoin, Ethereum, or blockchain startups. Others use their platforms to endorse new coins, NFT projects, or exchanges. Their presence brings mainstream attention to digital assets, accelerating public interest and adoption.

However, celebrity involvement is a double-edged sword. While some stars have backed legitimate, forward-thinking blockchain initiatives, others have promoted questionable coins or been associated with failed projects. From genuine believers to bandwagoners, the impact of celebrity actions in the crypto world has been both powerful and polarizing.

Elon Musk – Bitcoin, Dogecoin, Ethereum

Elon Musk isn’t just a tech mogul; he’s a major voice in the crypto world. Tesla’s $1.5 billion Bitcoin investment in 2021, followed by their decision to accept BTC payments, marked a turning point.

Although Tesla later sold 75% of its BTC citing environmental concerns, they still hold around 10,000 BTC. Musk is particularly fond of Dogecoin—calling himself the “Dogefather”—and is speculated to own a large share. He also holds Ethereum and has stated he intends to "HODL" his assets.

Gwyneth Paltrow – Bitcoin

In 2017, the Oscar-winning actress, Gwyneth Paltrow became an investor in the Bitcoin wallet app Abra, lending credibility to the space and helping increase public trust in Bitcoin.

Maisie Williams – Bitcoin

The Game of Thrones star asked her fans on Twitter if she should buy Bitcoin. Despite most voters saying no, she went ahead—and profited. Since then, she’s become an outspoken supporter.

Mike Tyson – Bitcoin

Tyson has been involved with Bitcoin since 2016, even launching a branded wallet with Bitcoin Direct.

Despite his Bitcoin ATM venture not taking off, Tyson remains an enthusiastic crypto supporter.

Snoop Dogg – Bitcoin, Ethereum, NFTs

Snoop embraced crypto early on, accepting it as payment for his music in 2013. He’s since promoted various crypto-friendly businesses and revealed himself as NFT collector “Cozomo de’ Medici,” actively investing in Bitcoin, Ethereum, and numerous NFT projects.

Lindsay Lohan – Ethereum, NFTs

Living in tax-free Dubai, Lohan has launched several NFT collections on the Ethereum blockchain, combining music and digital art. She’s a consistent promoter of blockchain technology and decentralization.

Tom Brady – Bitcoin, FTX

The NFL legend was a prominent ambassador for FTX, holding 1.8 million shares alongside then-wife Gisele Bündchen. After the exchange collapsed, they reportedly lost $30 million. While he was later compensated, Brady remains optimistic about DeFi’s future.

Paris Hilton – Ethereum, NFTs

Paris Hilton was an early backer of crypto and one of the first celebrities to launch her own NFTs. She played a key role in bringing crypto and digital collectibles into mainstream pop culture.

Ashton Kutcher - Bitcoin, Ethereum, Blockchain Ventures

Serena Williams – Coinbase

In 2019, Serena revealed her firm Serena Ventures had invested in Coinbase, signaling trust in crypto as a stable asset class and encouraging other athletes to follow suit.

Celebrities Who Promoted Cryptocurrencies

Celebrity promotions in crypto can be powerful but risky. When informed and transparent, endorsements like Reese Witherspoon’s help drive awareness. But when driven by compensation without understanding, they can mislead audiences and damage reputations.

Matt Damon – Crypto.com

Damon’s “Fortune Favors the Brave” campaign for Crypto.com was widely seen but unfortunately coincided with a crypto market downturn, leading to criticism despite his good intentions.

Kim Kardashian – EthereumMax

Kardashian promoted EthereumMax on Instagram without disclosing it was a paid endorsement. The SEC fined her $1.26 million. Since then, she’s avoided any further public crypto engagement.
