Co-founder of BitMEX crypto exchange and an Oxford graduate Ben Delo has become Britain’s youngest self-made billionaire, Daily Mail reports July 2.

Aged 34, Delo, who founded BitMEX in 2014, told Daily Mail that he used to spend 18 hours a day to build his platform. His work has apparently paid off, as BitMEX is currently one of the largest crypto exchanges in the world with a daily trade volume of around $2 billion, according to data from Coinmarketcap.

“I have had my nose down in a start-up for the past four years. I was doing 18-hour days at one point.”

Delo graduated Worcester College, Oxford in 2005 with a first-class degree, majoring in mathematics and computer science. Having experience as Software Engineer at IBM, and assistant Vice President at JP Morgan, the youngest UK’s Bitcoin (BTC) billionaire is now based in Hong Kong, according to Daily Mail.

Delo told that he mimics the frugal lifestyles of the U.S. billionaire investor Warren Buffett and entrepreneur Bill Gates, claiming that he prefers to give away his money to various charities.

In January, a representative of BitInfoCharts claimed the company estimated that there were no fewer than 35 Bitcoin billionaires worldwide, and possibly as many as 200.

In December, Winklevoss twins made the headlines by becoming the first “official” Bitcoin billionaires, reportedly holding about 91,666 bitcoins,worth about $1.063 billion at the time.
