I just want to say that Kraken has been the best exchange for me. With Justcoin a close second. Kraken have been extremely professional and they obviously have put a bit of thought into their in-house technology. The speed of SEPA withdrawals has been next-day for me every time. Incredible stuff.

Keep up the great work guys.
