What Does CZ Mean in Crypto?

CZ stands for Changpeng Zhao, the founder and former CEO of Binance, the world’s largest cryptocurrency exchange by trading volume. In crypto conversations, CZ is used as shorthand for the person himself, one of the most recognizable and influential figures in the industry.

Who Is Changpeng Zhao?

Changpeng Zhao was born in China and raised in Canada, where he studied computer science. Before crypto he built high-frequency trading systems, working on Bloomberg’s Tradebook and later as chief technology officer at the exchange OKCoin. He discovered Bitcoin around 2013 and committed to it full time. In 2017 he launched Binance, funded in part through an ICO of its BNB token, and within months it became the largest exchange by volume.

CZ, Binance, and BNB

Under CZ, Binance grew from a single CEX into a broad ecosystem. It added P2P trading, a launchpad for new tokens, and its own EVM-compatible network, BNB Chain. The BNB token sits at the center of that ecosystem, used for fees, token launches, and on-chain applications. CZ’s personal stake made him one of the wealthiest people in crypto.

Why CZ Stepped Down

In November 2023, CZ pleaded guilty to United States charges for failing to maintain an adequate anti-money-laundering program at Binance. The company agreed to pay roughly $4.3 billion in penalties, and CZ resigned as CEO, handing the role to Richard Teng. In 2024 he served about four months in prison before his release. He remained a major BNB holder and a closely followed voice in the industry.

Why CZ Matters in Crypto

Few individuals have shaped crypto as directly as CZ. The decisions he made at Binance influenced how millions of people trade, and his posts on social media still move markets. Even after stepping down, CZ remains community shorthand for the founder who built the industry’s largest exchange from scratch, and a reminder of how closely regulators now watch the space.
