Kraken is a US-based cryptocurrency exchange established in 2011, just two years after the mining of the first Bitcoin block, the Genesis block. It caters to 10M+ clients from 190+ countries with quarterly trading volume exceeding $200 billion. Cryptocurrency traders can use the mobile app or the advanced Kraken Pro web-based trading platform.
