@cryptographic,
This is the 1st time I decided to visit their page! Actually I heard about them before, but never tried their services! Today I checked them and found these details. My country has one of the top notch stupid rule as we can't send bank wires out of the country. So, again I got no chance to try this exchanges as well.
Here What I found about Kraken and I am suggesting you to review CEX.IO and COINMAMA.COM as well. Those exchanges has credit card options and allow my country to BUY crypto via them. Actually I wish you will compare those exchanges after your introduction about them.

I have found these information via https://coincentral.com/kraken-exchange-review/, therefore I can't give 100% guarantee about it. Because it's not my personal experience.
