The bitcoin exchange that made headlines when it launched earlier this month for $50,000 (£34,000) said on Wednesday that it had sold more than $600m worth of the digital currency.
According to data compiled by CoinDesk, the price of a bitcoin traded on Kraken between April 20 and May 17 climbed from around $6,000 on its initial public offering to around $9,000 a few days later, after it was launched on June 5.
Kraken, which is operated by Canadian company Kraken Technologies Inc, has a history of success in the space, trading nearly $5m in digital currency at a time when many exchanges are struggling to keep up with the demand.
Its main competitor, Bitfinex, is also part of the cryptocurrency space, but the exchange has seen its share of problems, with users complaining of a lack of security, fraud, and technical issues.
Kurzcash, which launched in June, said that it has sold over $1bn worth of bitcoin.
Its trading volumes have been growing rapidly, with the price now at over $6m a day.
