Crypto exchanges that have been operating continuously since 2013 are a small and shrinking group, and CEX.IO is one of them. Founded in London in 2013, the platform began as a Bitcoin exchange and mining pool before exiting cloud mining to focus on the trading and crypto financial services that have defined its trajectory ever since. The exchange offers spot trading, staking, lending, and crypto-to-card services across more than 200 countries, with regulatory registrations across multiple jurisdictions including the UK, US, and Gibraltar. The longevity is the differentiator — operating reliably across multiple crypto market cycles, surviving the 2018 and 2022 corrections, and maintaining the regulatory and operational discipline that has eliminated dozens of similar platforms over the same period. CEX.IO has built its product around accessibility for newer crypto users alongside the trading depth that more sophisticated users require, navigating the constant tension between mainstream usability and crypto-native functionality. In the European crypto exchange landscape, where the largest international platforms compete on liquidity and asset coverage, CEX.IO occupies the segment that prioritises the combination of regulatory standing across major jurisdictions, fiat onramp accessibility, and the kind of operational record that takes a decade to build and that newer competitors cannot acquire by other means.
