How Changpeng Zhao Built Binance: From Zero to the World's Largest Crypto Exchange

The story of how Changpeng Zhao built Binance into the world's largest cryptocurrency exchange is one of the most remarkable entrepreneurial journeys of the past decade. It does not start in Silicon Valley. It does not start with venture capital or an Ivy League network. It starts in rural China, in a family with very little money, in a country that was still finding its footing on the world stage.

Growing Up in Rural China

CZ was born in Jiangsu province, China. His family was not wealthy. His father was an academic whose career was disrupted during a period of political turmoil, and the family lived modestly. CZ has spoken about the experience of growing up without many of the material comforts that his eventual success would make seem routine.

When CZ was a teenager, his family immigrated to Canada, settling in Vancouver. The transition was not easy. CZ worked jobs to help support himself and his family while attending school in a new country, learning to navigate a culture and language that were not his own.

He went on to study computer science at McGill University in Montreal — one of Canada's top research universities. The technical foundation he built there would later prove decisive in how he approached building Binance.

Early Career: From Stock Exchanges to Bitcoin

After university, CZ worked in traditional finance. He built trading systems for the Tokyo Stock Exchange and worked at Bloomberg Tradebook, where he developed expertise in the technical infrastructure of financial markets. He was good at it, and he understood at a deep level how exchanges actually worked — not just theoretically, but operationally.

Around 2013, CZ encountered Bitcoin. The story, which he has told in interviews and which he covers in detail in his memoir Freedom of Money, involves a poker game where he first heard about it in depth. He went home and started researching. What he found convinced him that Bitcoin was genuinely significant — not a passing novelty but something that could reshape global finance.

His response was characteristically decisive. He sold his apartment in Shanghai and put the proceeds into Bitcoin. It was not a small bet.

OKCoin, Blockchain.info, and Learning the Industry

CZ spent several years working inside the crypto industry before founding Binance. He joined Blockchain.info (now Blockchain.com) and later became CTO of OKCoin, one of the major Chinese crypto exchanges at the time. These roles gave him a deep understanding of how crypto exchanges operated — and where they fell short.

By 2017, he had a clear picture of the opportunity: a global crypto exchange built for speed, with competitive fees, a clean product, and a token economy that aligned user incentives with the platform's growth. The idea became Binance.

Launching Binance in 2017

Binance launched in July 2017, during what was then a remarkable bull market for cryptocurrency. The timing was favorable. But timing alone does not explain what happened next.

Within six months of launch, Binance was the largest cryptocurrency exchange in the world by trading volume. That growth was driven by several decisions that CZ and the Binance team made early on:

The BNB token. Binance launched its own exchange token (Binance Coin, or BNB) which gave holders discounts on trading fees. This created an immediate incentive to hold BNB and a built-in demand floor for the token. It also gave the exchange a direct revenue lever and a community with skin in the game.

Low fees. Binance launched with lower trading fees than most competitors. Combined with the BNB discount, this made it economically attractive for serious traders.

Speed of execution. CZ built Binance with an extreme bias toward shipping fast. New trading pairs, new features, new products — Binance moved faster than almost any competitor. That pace attracted users and kept them engaged.

Global from day one. Binance did not focus on a single market. From the beginning it was accessible internationally, which meant it could capture growth across all the markets where crypto was accelerating simultaneously.

Scaling to 300 Million Users

From 2018 through 2022, Binance expanded into nearly every corner of the crypto industry. It launched futures trading and leveraged products. It built Binance Smart Chain, its own blockchain, which became a major hub for DeFi applications. It launched NFT marketplaces, staking products, a crypto debit card, and financial products that rivaled traditional banks in scope and reach.

At its peak, Binance processed more daily trading volume than the New York Stock Exchange. It had approximately 300 million registered users across the globe. CZ's personal net worth was estimated in the tens of billions of dollars, making him one of the wealthiest people on the planet — at least on paper.

The Regulatory Reckoning

Binance's growth happened faster than its compliance infrastructure could support. The company faced scrutiny in multiple jurisdictions — the UK's Financial Conduct Authority, regulators in Japan, Germany, and eventually the United States Department of Justice.

The DOJ investigation focused on Binance's anti-money laundering compliance failures. In November 2023, Binance agreed to a $4.3 billion settlement — one of the largest in corporate history. CZ stepped down as CEO and pleaded guilty to a single Bank Secrecy Act violation, paying a $150 million personal fine. He served approximately four months in U.S. federal prison.

No Binance customers lost funds. The charges were compliance failures, not fraud.

The Book: His Full Account

CZ wrote Freedom of Money largely during his prison sentence. The 366-page memoir covers the full arc of his story — from childhood in Jiangsu province to building Binance, the FTX collapse, the DOJ case, and life inside a U.S. federal prison.

It is currently ranked #1 in Bitcoin & Cryptocurrencies on Amazon, available in Kindle and Paperback. CZ donates 100% of his author royalties to charitable causes.
