Early Life and Immigration to Canada CZ's father immigrated to Canada in 1984 from China for an exchange program at the University of Toronto, later moving to UBC. The family's application for a Chinese passport and Canadian visa took several years, eventually allowing them to immigrate in 1989, shortly after the Tiananmen Square incident. Upon arrival in Vancouver, CZ, then 12, knew little English. His father worked as an assistant professor, earning $1,000 CAD per month. His mother, a math and history teacher in China, worked in a sewing factory for minimum wage for 7-10 years due to language barriers. CZ started his first job at McDonald's at age 14 or 15, earning $4.50, below the minimum wage of $6 due to a special exemption for young workers. He describes his teenage years in Canada as instrumental in shaping him into a happy and stable person. Education and Early Career CZ initially studied biology at McGill University but switched to computer science after one semester. He financed his education by working every summer and part-time during the school year, graduating without student debt. He did not officially graduate from McGill, leaving for an internship in his third year, and later obtained a bachelor's degree from the American College of Computer Science via an online program for work visa requirements in Japan. His first programming job was in Tokyo at Fusion Systems, writing order execution systems for brokers of the Tokyo Stock Exchange. He found the work appealing due to its focus on efficiency and low latency, requiring significant technical expertise. He describes optimizing software by removing database lookups, performing operations in memory, and simplifying risk checks, eventually moving to FPGA for even lower latency. He explains that custom ASICs are not widely used in high-frequency trading because algorithms change too frequently, making FPGAs a better balance between efficiency and adaptability. Fusion Systems was later sold for $52 million, but CZ, being a young coder, did not receive any proceeds. After Fusion Systems, he joined a failed startup with zero revenue, learning that "previous success doesn't guarantee future success." He then worked at Bloomberg in New York for four years (2001-2005) as a senior developer, leading a team of up to 80 people. Entrepreneurial Ventures in China In 2005, CZ moved to Shanghai with five friends to start a fintech company, aiming to bring Wall Street trading technology to China. He was a junior partner, owning 11% equity, but was unaware of shareholder rights or preferred vs. common stock. They discovered Chinese financial institutions couldn't work with wholly foreign-owned enterprises, forcing them to pivot to IT "work-for-hire" services. The company became successful, serving automotive clients like Shanghai General Motors and later expanding to Hong Kong, working with Morgan Stanley and Deutsche Bank. CZ left the company in 2013 after 8 years, having invested most of his savings back into it and not cashing out any profit, though it paid six-figure salaries allowing partners' children to attend international schools. Discovery of Bitcoin and Binance's Genesis In July 2013, a friend, Ron Tao, introduced CZ to Bitcoin. It took him about six months to fully understand it after reading the white paper and engaging with the community. He also had lunch with Bobby Lee, who was about to become CEO of BTCC, who advised him to put 10% of his net worth into Bitcoin. Despite Bitcoin's price soaring from $70 to $1,000 by the end of 2013, CZ initially felt he was "too late." He attended a Bitcoin conference in Las Vegas in December 2013, meeting early figures like Vitalik Buterin and Charlie Lee, and realizing the community was composed of "nice people" despite negative media perception. Convinced by Bitcoin's potential, CZ told his partners he would quit to work in the industry and sold his Shanghai apartment for nearly $900,000 to buy Bitcoin, averaging an entry price of $600 as the price dropped. He briefly worked as VP of Engineering at Blockchain.info (6-7 months), learning about remote work (paying in Bitcoin) and guerrilla marketing. He then became CTO at OKCoin (8 months), leaving due to cultural differences, including deceptive promotion practices. In 2015, after the Mt. Gox incident, CZ, with two former colleagues, decided to build a Bitcoin exchange in Japan to fill the market vacuum. They quickly developed a demo using an open-source exchange software and Bitfinex market data. Investors were impressed by CZ's deep technical knowledge but advised against running an exchange in Japan due to language barriers. They pivoted to selling their exchange technology as a "software as a service" (SaaS) provider, signing a contract for $360,000 and making a down payment of $180,000. Over two years, this business licensed software to 30 different exchange clients, generating multi-million dollar revenue. In March 2017, the Chinese government shut down most of their clients, forcing another pivot. In May 2017, CZ decided to launch their own crypto-to-crypto exchange, seeing an opportunity after a co-founder of BTC.com successfully raised $15 million via an ICO with just a white paper. Binance launched in July 2017, raising $15 million by selling 60% of BNB tokens (Binance Coin) to approximately 20,000 largely Chinese buyers. The main utility was a 50% fee discount on the Binance platform. In September 2017, the Chinese government banned crypto exchanges and ICOs. Binance, with 30 people, quickly moved its operations to Tokyo. Binance achieved product-market fit due to a hot crypto market, its token-based fee discounts, and superior technical performance compared to competitors like Poloniex and Bittrex. Binance's Growth and Challenges CZ describes Binance's early success as "surreal," with rapid revenue growth and the BNB token price soaring by 20% consistently. He measures success by Daily Active Users (DAO), believing that providing value to more users is paramount for long-term growth, rather than short-term revenue or profit. The first indication of "bad actors" was on New Year's Day 2018, when a US Homeland Security agent contacted Binance for help tracking funds from the EtherDelta hack. This led CZ to realize the need for law enforcement interface. In 2019, Binance launched Binance US as a separate, regulated entity after observing increased US government scrutiny on other exchanges like BitMEX and Bitfinex. CZ met Sam Bankman-Fried (SBF) in January 2019. Binance later invested 20% equity in FTX and acquired FT tokens. CZ recounts SBF's aggressive tactics, including badmouthing Binance in Washington and poaching employees with VIP client access. Binance exited its investment in FTX in July 2021, a year and a half before FTX's collapse, due to SBF's behavior and the perception that FTX was overvalued. CZ asserts he never asked for FTX's financial statements as a passive investor. Legal Challenges and Prison US government inquiries into Binance escalated in late 2022, becoming overtly hostile by early 2023, leading to negotiations for a deal or indictment. CZ describes the legal process as stressful, relying on diverse legal advice from many lawyers, which he found "tricky" and prone to tangents. He considered the best-case scenario as a fine and a Deferred Prosecution Agreement (DPA), and the worst-case scenario as imprisonment. He chose to face the charges in the US rather than remaining in the UAE (a non-extradition country) to avoid limiting his travel and causing trouble for the UAE government. Negotiations involved daily calls with 12-20 lawyers for over a year, with lawyers noting the government's unprecedented hostility. CZ recounted periods of "purgatory" where negotiations stalled, and he considered the possibility of a sealed indictment and a life confined to one country. He believes the DOJ used these silences as a "very useful negotiation tactic." The eventual plea agreement involved a single charge of banking secrecy act violation (registration failure), a federal crime for which no one had previously gone to jail. This charge was distinct from money laundering or aiding illicit transactions, focusing on Binance's failure to register as a financial services company in the US and inadequate KYC/AML procedures. The government tried to add two "enhancement" charges (layers three and four) alleging CZ's personal facilitation of bad transactions, but the court ultimately rejected these due to lack of evidence. Before going to the US, CZ was confident he wouldn't face jail time, based on legal advice and precedents like Arthur Hayes' six months of home confinement. Upon landing in the US, he stayed in a hotel in Seattle, joined by his mother and sister. The judge initially allowed him to return to the UAE pending sentencing, but the government appealed, resulting in CZ being confined to the US for six months (two three-month extensions) before sentencing. A week before his sentencing on April 30, 2024, the government requested 36 months in prison, double the maximum sentencing guideline, which his lawyers found unusual. Senator Elizabeth Warren's public declaration of "war on crypto" five days before his sentencing added to the pressure. The judge ultimately sentenced him to four months in prison, saying many good things about him but also acknowledging the violation. Concerns about safety and extortion in prison due to media coverage and his wealth were prominent. He received advice from prison consultants (ex-guards, ex-inmates). He learned that US prisons are often organized by ethnicity, which guards encourage to reduce conflicts. As a non-US citizen, he was sent to a low-security prison with drug offenders, rather than a minimum-security facility. Upon release on September 27, 2024, he immediately flew back to the UAE, having spent a year in America and not seeing his children for that period. Post-Binance Life and Future Endeavors CZ is "okay" with no longer running Binance; stepping down was initially difficult and emotional, but he now has more free time and recognizes other meaningful things he can do. He believes a presidential pardon for him would allow Binance to properly enter the US market and contribute to the US becoming a crypto capital. He speculates President Biden's own legal issues may foster sympathy. His current activities include: Giggle Academy: a free, gamified, fully digitized education platform delivered via a mobile app, aiming to educate the 1.2 billion illiterate adults and out-of-school children globally. He resists issuing a token for it to prevent speculation and ensure genuine learning. Consulting with governments on crypto regulatory policies. Investing in blockchain, AI, and biotech through his labs. Mentoring founders in the BNB chain ecosystem. CZ sees AI as the third fundamental technology of his life (after the Internet and Bitcoin). He envisions AI agents transacting money at a scale and speed that traditional banks cannot handle, making crypto essential for their payment systems. He believes privacy in crypto is a fundamental societal need and a missing feature in most cryptocurrencies, including Bitcoin, which limits their ubiquitous adoption. He is writing a book to share his story, address misconceptions about himself and Binance, and provide his perspective on the industry, especially for his children. He emphasizes that success does not require being "super smart" but rather values, emotional intelligence, and consistent effort (pushing oneself to 110-130% without burning out) over decades. He believes money is just "one thread" in life; beyond a comfortable amount, more money doesn't guarantee happiness. Health, family, time, and positive impact are equally, if not more, important.
