once my bank did not allowed me to transfer money to exchange (Lite Bit) to buy Bitcoin, they told me LB's bank account is marked red, as they support terrorism 😂🙈

I had the same issue with Kraken when I was living in France. It was impossible to transfer funds in the beginning, but they got that sorted out after.
The banks have to be FATCA (it's an anti laundering, anti terrorism regulation) compliant, that why they do this sort of checks.
