Our take
Kraken is the world’s largest global bitcoin exchange in euro volume and liquidity. Kraken’s clients also trade USD, CAD, ETH, XRP, LTC and other digital currencies, on a platform consistently rated the best and most secure bitcoin exchange by independent news media.
Kraken was the first bitcoin exchange to have its market data displayed on the Bloomberg Terminal, the first to pass a cryptographically verifiable proof-of-reserves audit, and one of the first exchanges to offer leveraged bitcoin margin trading.
Kraken are one of the top 3 bitcoin exchanges by volume, behind Coinbase and bit-x with an 18% market share. While this is a competitive space to operate in - the volume of crypto being exchanged every day is very high, so there's space for multiple winners.
Kraken have made a number of acquisitions and have strengthened its world-leading position with the launch of new products, features and apps and a 24/7 multi-lingual support line. The company will continue to provide clients with easier and more versatile ways to participate in the crypto ecosystem.
