Users of cryptocurrency exchange Coinbase and crypto data provider CoinMarketCap received the surprise of their life on Tuesday afternoon when they checked their accounts and found enormous gains, leading some to believe they’d become millionaires, until the companies clarified on social media that it was a glitch.

Coinbase acknowledged on Twitter that some of its customers were seeing “inflated values” after social media users reported huge cryptocurrency gains that bumped their assets into the millions around 4 p.m. EST.

Coinbase said the malfunction was a display issue only and had not impacted trading — it said resolved the issue on the website at about 5:30 p.m. EST and on its Coinbase Wallet app at around 6:30 p.m. EST.
