Over the past few years I’ve dabbled with a few cryptocurrency exchanges. Recently I came across Kraken which I’m now using. I’ve found Kraken to be far more efficient in their due diligence screening process for new accounts although they still require the same amount of documentation to authorize your account for deposits and withdrawals. The system is simple to use, feature full and offers variety of trading pairs between fiat currency and cryptocurrency and between two cryptocurrencies. An interesting interview with the founder of the exchange can be viewed here if you’d like to learn more about how Kraken was started and other interesting details: http://www.newfination.com...
