Kraken banks with Fidor, so I can't see them having any issues. Unfortunately for me Fidor only onboard German companies and EU individuals.I've had a Fidor.de bank account for some time (EU citizen, Cyprus resident). However I must warn that Fidor customer service sucks in a big way. Getting a reply to a customer service ticket took three weeks, and it did not even begin solving my issue. Hopefully their telephone service works better. It seems to me, as a digital bank they are 2nd tier, not as streamlined as e.g. TransferWise.
Earlier I have transfered a low five figures from Kraken to Fidor without issues.
