# Okcoin

> Founded by Star Xu in 2013, Okcoin grew from a Bitcoin exchange into a global crypto trading platform with retail trading, institutional tools and APIs. China's 2017 exchange crackdown forced an early geographic reset. A later consolidation under the OKX brand moved European users in 2024 and phased out US Okcoin trading in May 2025. The Okcoin name now chiefly marks the history, legal entities and withdrawal support behind that transition.
