From my recent experience,online banks are getting more problematic and useless everyday.
Bunq is a great example of it, they offer multi IBAN accounts and a 1 month free trial, however if you start doing many transfers they will simply block your account and retain your funds until they decide to pay them. Even if not using any crypto related transactions, but some casual 4 digit transfers or anything related to Gambling,Reselling,paypal,Skrill,Neteller and you are dead.
I Find some local banks still more flexible than them.
