You can only access
https://mixercasino.com/ after creating a login account. You mentioned about what currency you accept but no info about how you make payments. There is no such thing as FAQs.
We need some basic info about the site before we create account. Its just my suggestion to make some basic info available on the site for every visitor.
Click the payment button on the menu bar and it provides you with a qr code and address for deposits.
