Today I found out out that the fidor API is not cost free but actually has to be purchased. I am pretty sure this is the reason for the 0.09€ fee. And I am wondering: is it also the reason why the frequency of the payment bot is set to 1 hour and not more often?
I don't thing the charge 0f 0.09€ has to do with one special thing. I guess it's just an additional way to earn money and pay the complete operating costs of all aspects of an exchange. So you also could ask why they charge 0.3% fee for trading, if the operating costs is just 0.01% per trade (just example numbers).
But would be interesting to hear, if I'm right or not ^^
My understanding is that with the bank fees we just pass along the per transfer fees that we are charged by our partner banks or payment providers. We have other costs associated with the payment options we provide, so there is no profit in the bank fees. All the bank fees do is help reduce our costs on the banking side of operations by a small amount.
Edit: our CEO asked me to add that bank fees also serve as a kind of spam control
That's reasonable. IMHO an amount of 9 cents is not worth to discuss...
I did not intend to question the €0.09 fee. Since the reason for the fee lies in fidor API usage fees (kraken pays Fidor), I was ratther wondering: is that the reason why the kraken payment bot only checks fidor playments once/hour? That translates into: is the fidor API usage fee a flat fee or a per usage fee?
