According to BitReview…
Kraken is one of the best products in the market, period. For European traders, Kraken is hands down the best bitcoin exchange option. The trading platform, which is arguably the best of all the bitcoin exchanges, is number one in terms of BTC/EUR trading volume. Kraken has recently slashed trading fees, catapulting what was already a competitive structure into top two or three.
Established in 2011, San Francisco’s Kraken is a large Bitcoin exchange in euro volume and liquidity and also permits trading Canadian dollars, US dollars, British pounds and Japanese yen. It was the first Bitcoin exchange to have trading price and volume displayed on the Bloomberg Terminal. Kraken was one of the first exchanges to pass a cryptographically verifiable proof-of-reserves audit, and partnered with Germany’s online direct bank Fidor Bank to form the world’s first cryptocurrency bank.
Kraken is also the court-appointed trustee in Japan that is handling creditor claims from the Mt. Gox Exchange collapse and bankruptccy.
