Northcasino seems like a very legitimate casino website where you can place bets and earn double of your wager this company has been operating for more than two years now and they claim to give new registered members $500 bonus after registration but I don't think that you can withdraw this $500 to your bank account instead it will only be used to place bet on the website which is still fair because you don't expect to gain from what you don't invest from but I think if you wager it at a particular number of times you should be able to withdraw the remaining balance to your account.
You can easily sign up on their website after that you can add up some money to your account which will be used to place the bets, and I will suggest that you place bet with an amount which you can afford to lose so you won't be financially affected if things doesn't go as planned, you can contact their customer support for help if you're facing any issues on their website.
