Before my first deposit: what to check at Lucky Circus Casino?

About to make my first deposit at Lucky Circus Casino and trying to do it properly this time, not just click and hope. It holds a Curaçao licence, which is fine by me, but a licence on paper doesn't tell me how things work day to day.

Since I'm completely new to this place, I'd rather hear from people who already play there than learn everything the hard way. Things like the verification process, how fast the first cashout goes through and whether the bonus terms hide anything annoying are what worry me most.

Anyone with a few months on the site: what would you check before putting in the first euro? And is there a small mistake newcomers tend to make here that I should dodge?
