Newbie question: what to check before depositing at Iwin Casino

Thinking about opening an account at Iwin Casino and making my first deposit soon. Total newcomer here, so I'd rather hear from people who know the place than learn everything the hard way.

From what I can tell, it holds a Curaçao licence, and it seems to draw a lot of players from India and Brazil, with some in the UK and Canada too. That's about all I've got, and I'd like the real picture from regulars before I put any money in.

For those of you already playing there: what would you check first, like the wagering terms, the verification process, or the payment options at the cashier? And is there anything you wish somebody had told you before your first deposit?
