How do withdrawals work at 20-win Casino?

Thinking about giving 20-win Casino a proper go, but the cashout side matters more to me than any welcome offer. From what I gather it runs under a Curaçao licence, and it seems to get a lot of attention from players in Brazil, with some in India too.

What I really want to know is how the verification goes. Do they ask for documents right at signup, or only when you request your first payout… and how long did it take before the money actually landed?

If you've pulled out a bigger win there, did they ask for anything extra, like proof of address or a source of funds? Would love to hear how it went for you, especially if you're playing from Brazil.
