21. Song Chi-hyung, net worth: $1 billion (£744m)
The crypto crash of 2022 knocked a number of the industry's elite off the billionaire pedestal, including Song Chi-hyung, the co-founder and chairman of Dunamu, the firm behind Upbit, South Korea's leading crypto exchange.
With the market on a spectacular bull run since last year, Song recently regained his billionaire status, unlike his Dunamu co-founder Kim Hyoung-nyon, who has yet to recover his former fortune.

=19. Joe Lau, net worth: $1.5 billion (£1.1bn)
Joe Lau joined the billionaire club in early 2022 when Alchemy, the blockchain software company he co-founded in 2020, reached a peak valuation of $10.2 billion (£7.6bn). The number has since dropped to around $6 billion (£4.5bn), due mainly to the general decrease in the valuations of private tech companies over the past three years, according to Forbes.
Lau's wealth has declined in tandem, falling from $2.4 billion (£1.8bn) in 2022 to $1.5 billion (£1.1bn) at the last count.

=19. Nikil Viswanathan, net worth: $1.5 billion (£1.1bn)
Nikil Viswanathan started Alchemy alongside Lau in 2020. The duo met while studying at Stanford University and cut their entrepreneurial teeth with the meetup app Down To Lunch before venturing into the crypto space.
Like Lau, Viswanathan holds a 26% stake in the San Francisco-based company and has seen his net worth decline since 2022 in step with Alchemy’s valuation. Still, the crypto software whizz and his co-founder remain firmly in the billionaire ranks.

=17. Matthew Roszak, net worth: $2.9 billion (£2.2bn)
Matthew Roszak is the co-founder and chairman of Bloq, a leading US provider of blockchain infrastructure solutions. A former venture capitalist turned early Bitcoin investor, Roszak is a well-known figure in the crypto space and a vocal advocate for blockchain innovation. He has also chaired the Digital Chamber, the world’s largest trade association representing the blockchain industry.
Roszak became a billionaire in 2021 when his net worth reached $1.5 billion (£1.1bn). It peaked at $3.1 billion (£2.3bn) in 2024, before dipping earlier this year.

=17. Jed McCaleb, net worth: $2.9 billion (£2.2bn)
Another industry veteran, Jed McCaleb played an important role in the early blockchain days, co-founding three companies that helped shape the industry: Mt. Gox, the first ever Bitcoin exchange, as well as digital payment firms Ripple and Stellar.
As a Ripple co-founder, McCaleb bagged nine billion units of its native crypto XRP, the key source of his wealth. Given he cashed in the lot by 2022, McCaleb's fortune is now largely realised, rooted in hard currency and tangible assets rather than on-paper token valuations, unlike many of his crypto peers.

Seasoned Silicon Valley investor Tim Draper lucked out big-time in 2014 when he snapped up 29,656 bitcoins confiscated by US authorities from the notorious Silk Road online black market. Draper paid just $632 (£469) per coin, an incredible bargain in hindsight.
With Bitcoin hitting record highs and each coin now worth well over $118,000 (£87k), Draper’s crypto fortune has surged to $3.6 billion (£2.7bn), up from $2 billion (£1.5bn) last year and $1.2 billion (£891m) in 2022.

15. Jeremy Allaire, net worth: $4.1 billion (£3bn)
The newest member of the billionaire crypto club, Jeremy Allaire joined the coveted clique in June after his New York-headquartered firm Circle, which is behind the up-and-coming USDC stablecoin, went public in a showstopping IPO. Circle stock jumped over 200% on day one, making Allaire’s fortune soar.
The share price has continued to shoot up, as has Allaire's net worth, which just hit $4.4 billion (£3.3bn).

=12. Cameron Winklevoss, net worth: $4.4 billion (£3.3bn)
Along with his identical twin brother Tyler, Cameron Winklevoss shot to fame after suing Mark Zuckerberg over claims he stole the idea for Facebook from them. Using part of their multimillion-dollar settlement, the siblings began buying Bitcoins way back in 2012 when each coin was worth less than $10 (£7). Two years later, the early crypto advocates launched Gemini, one of America's first regulated exchanges for crypto.
The brothers reportedly hold around 70,000 Bitcoins. Given the surge in the crypto's value, their respective fortunes have swelled by around $1.6 billion (£1.2bn) in the past year alone.

=12. Tyler Winklevoss, net worth: $4.4 billion (£3.3bn)
The twins remain very hands-on at Gemini, with Cameron serving as president and Tyler as CEO. Not ones to rest on their laurels, they've put their all into making the crypto exchange a huge success, and it now processes an impressive $30 million (£22m) in trades a day. But the pair's achievements extend well beyond tech and finance.
The Winklevii, as they're nicknamed, are also world-class athletes. Accomplished rowers, they competed in the 2008 Olympics and have taken part in the prestigious Oxford-Cambridge Boat Race.

=12. Fred Ehrsam, net worth: $4.4 billion (£3.3bn)
Fred Ehrsam is the co-founder of Coinbase, America's number one crypto brokerage, which debuted in 2012. While he left to set up crypto investment firm Paradigm in 2017, Ehrsam continues to own a sizable 4% of Coinbase.
With the company's stock at an all-time high, the crypto pioneer's net worth has exploded this year, jumping from $2.7 billion (£2bn) in the spring to $4.4 billion (£3.3bn) at the last count.

11. Donald Trump, net worth: $5.3 billion (£3.9bn)
Now a bona fide crypto billionaire, the US president is raking it in from his questionable forays in the world of digital currencies. According to a Forbes study published in June, Trump's crypto holdings are now worth more than Trump Tower and Mar-a-Lago combined.
Launched in January, the POTUS' controversial $TRUMP meme coin has reportedly netted him $742 million (£551), while his other ventures, including his World Liberty stablecoin and NFT business, have pushed up the total to $1.2 billion (£891m).

10. Michael Novogratz, net worth: $6.1 billion (£4.5bn)
Michael Novogratz transitioned from Goldman Sachs and Fortress Investment Group to crypto back in 2013, investing in Bitcoin in those halcyon early days when it cost peanuts. Novogratz went on to found Galaxy Digital Holdings, one of the world's top crypto investment firms, and remains the company CEO and majority shareholder.
It hasn't all been plain sailing, with Novogratz losing big in 2022 after backing the ill-fated Terra Luna crypto network, which collapsed in the space of three days in May of that year. Nonetheless, Novogratz's net worth has bounced back and then some, with the current figure of $6.1 billion (£4.5bn) more than double last year's number.

9. Stuart Hoegner, net worth: $6.2 billion (£4.6bn)
Stuart Hoegner is one of four billionaires created by Tether, the world's largest stablecoin issuer. Hoegner has served as general counsel since its founding in 2014 and owns a tidy 13% of the firm.
The British Virgin Islands-based company, which has blown away Wall Street with its incredible profitability, recently attained a record valuation of $160 billion (£118bn). This has boosted the fortunes of its four billionaires no end. Hoegner's net worth now stands at $6.2 billion (£4.6bn), up from $2.5 billion (£1.9bn) last year.
