Registration and verification
Every licensed operator must verify identity, address and payment ownership under anti-money-laundering rules. Expect to provide a government ID, a recent utility bill or bank statement, and proof that the payment method belongs to you. Verification is typically triggered at first withdrawal, sometimes at signup.
Complete verification before you deposit, not when you want your money. Documents submitted while a withdrawal is pending are what turns a two-day payout into a two-week one.
