CryptoBridge is a decentralized cryptocurrency exchange. It would be more accurate to say that this platform is a gateway to the Bitshares decentralized exchange. It features a wide range of supported altcoins (there are about 80 currencies available for trading). Some of these currencies are well-established and popular while others are quite new and not widely known. The company stresses that one of CryptoBridge's missions is to connect traders with new projects.
