They ask id card just for your verfication. They want to just check that you are genuine person.
If you join bittrex also there also you have to provide id for verification.

So Id verfication is not any harm. You can proceed.

In case you purchase crypto with a bank card, the verification procedure is handled by our card payments providers. Please keep in mind that it is just an additional measure to keep customers safe.
