Live test transactions will fail if they are below the minimum amount!
You should now be able to successfully use the Kraken Exchange with CAS.
Kraken requires a "trade agreement" in certain countries (e.g. Germany). If your Crypto Tests pass, but you cannot execute a trade, please follow their advice:
Please try to navigate to the Trade-tab using the web interface,
and then to the New Order page and then select Advanced there.
You should be prompted with a trading agreement you have to accept.
Once you have accepted this agreement you should not be prompted
with this message.
