Kraken is a cryptocurrency exchange with headquarters in San Francisco, California, United States that was launched in July 2011, making it one of the oldest existing cryptocurrency exchanges. It was founded by Jesse Powell, who remains the CEO of Kraken, but the exchange is now owned by Payward Inc.
Despite its location in the U.S. it bills itself as “the world’s largest Bitcoin exchange in euro volume and liquidity”, and it serves clients in Europe, the U.K., the U.S., Japan and other countries across the globe.
It is also noteworthy that Kraken is the exchange providing pricing data to the Bloomberg Terminal, as well as being the exchange chosen to provide Mt. Gox creditors with claim support following the catastrophic 2014 hack that saw 650,000 Bitcoin go missing.
