During registration, you are required to provide accurate, complete, and current information including your full name as per your identification card, an active Malaysian mobile number, and a valid email address. best66 reserves the right to request supporting document verification at any time to confirm a member's identity.

The KYC process will be triggered before your first withdrawal or when your cumulative transaction amount reaches a certain threshold. Required documents may include a copy of your MyKad, a recent bank statement, and proof of payment method. All documents are processed securely and deleted upon completion of verification.

  • Touch 'n Go eWallet, GrabPay, Boost, ShopeePay
  • DuitNow & interbank transfers (IBG)
  • Licensed Visa and Mastercard credit/debit cards
  • Supported cryptocurrencies (USDT, BTC, ETH)

Deposits are processed automatically and credited to your account in under 2 minutes. Withdrawals are processed within 15 to 30 minutes during normal hours, subject to completed KYC verification.

The minimum deposit amount is RM 30 for most payment methods. The minimum withdrawal limit is RM 50. The maximum daily withdrawal limit depends on your membership tier — VIP members enjoy higher limits. All withdrawals must be returned to the original payment method used for the deposit, in line with anti-money laundering policy.

Best66 does not charge any processing fees for standard deposits and withdrawals. However, third-party payment providers may apply their own charges, which are beyond best66's control.
