Founded in 2011, San Francisco-based Kraken is the largest Bitcoin exchange in euro volume and liquidity and also trading Canadian dollars, US dollars, British pounds and Japanese yen. Kraken is consistently rated the best and most secure Bitcoin exchange by independent news media.
Kraken was the first Bitcoin exchange to have trading price and volume displayed on the Bloomberg Terminal, the first to pass a cryptographically verifiable proof-of-reserves audit, and is a partner in the first cryptocurrency bank. Kraken is trusted by hundreds of thousands of traders, the Tokyo government's court-appointed trustee, and Germany's BaFin regulated Fidor Bank.
The best bitcoin exchange is needed for serious and professional bitcoin traders. Bitcoin security must be impeccable. Banking relationships must be sound and reliable. The trading engine must be fast. Order types must be advanced. And profits must be able to be multiplied with Bitcoin margin trading so you can leverage long bitcoin positions or short bitcoin positions.
