On any betting platform, the payment system is what matters most. If withdrawing your winnings is a hassle, or deposits take too long — the entire experience falls apart. ok big understands this completely, which is why our payment infrastructure has been built with Bangladesh's real-world needs in mind.
While most people in Bangladesh have bank accounts, mobile banking is far more widely used in day-to-day life. Mobile Pay and Nagad have become so commonplace that you'll find them everywhere — from roadside tea stalls to large shopping malls. ok big respects that reality and has made Mobile Pay and Nagad its primary payment methods.
A question many users ask — does ok big charge a service fee on deposits? The answer is no. Deposits on ok big are completely free. Send ৳1,000 and you'll see exactly ৳1,000 in your wallet. The same applies to withdrawals — ok big charges no withdrawal fees either.
Please note that your mobile banking provider (such as Mobile Pay or Nagad) may apply transaction fees based on their own policies — this is outside ok big's control. In most cases, these fees can be avoided by making payments directly through the Mobile Pay app.
Ok big aims to process every withdrawal request within 15 minutes. In practice, most requests are completed in 5–10 minutes. During peak periods — such as after a major match — processing may take slightly longer. VIP members' withdrawals receive the highest priority.
Withdrawals are available even after midnight. ok big's payment system runs 24/7, so if you win a bet watching a late-night match, you can withdraw your winnings right away.
Log in to the ok big app or website and go to the "Wallet" section. From there, click on "Transaction History" to view a full record of all your deposits, withdrawals, and betting transactions. You can also filter the results by date.
Every transaction comes with a unique transaction ID. If you experience any issue with a transaction, contact ok big's customer support with this ID for a fast resolution.
For your security, ok big may request account verification (KYC) before processing large withdrawals in certain cases. This is a standard and necessary procedure that keeps your account protected. Verification can typically be completed by submitting a photo of your National ID or passport.
