CoinX

Founded in late 2013, CoinX emerged as a significant altcoin trading platform during the early days of the cryptocurrency market. It gained notability for being one of the first exchanges to offer trading pairs for prominent early cryptocurrencies like Peercoin and Primecoin against Bitcoin. Operating in an era of nascent crypto adoption, the exchange provided a crucial venue for users to trade digital assets beyond Bitcoin. The company ceased operations and closed its platform around 2014.
