1 star given because I can't give none. I opened an account with Kraken and transferred just £100 from my bank (to Payward Ltd.) to begin with. This showed as a "pending" transaction in my Kraken account for over 3 days, even though it had been cleared by my bank. After I queried this pending status with Kraken support, I received an email that stated "Unfortunately we must inform you that we will be closing your Kraken account. For security purposes we cannot disclose the reason for this action. Kindly note that you cannot open another Kraken account and that our live chat and phone support channels will not be able to provide assistance regarding this matter." and the departing line was "We appreciate your understanding." !?!?! The only good thing that I can say is that I did receive my £100 back quite promptly.
