👤 Registration & Account

To register, you'll need an active Bangladeshi mobile number, a valid email address, and to be at least 18 years old. A photo of your National ID (NID) or passport will be required for KYC verification. The entire registration process takes just 2 minutes.

KYC (Know Your Customer) verification secures your account and prevents unauthorized access. Without it, withdrawal limits may apply. Verification is typically completed within 24 hours of submitting a clear photo of your NID or passport.

No. Per 21 winbd policy, each person may only register one account. If multiple accounts are detected, all of them may be suspended and any funds held could be forfeited.

After logging in, go to "My Account" or your profile settings. Changing your name, email, or mobile number requires OTP verification. For updates to bank account or mobile banking details, please contact the support team.

If your account is closed or suspended, email support@21winbd.biz or contact us via live chat immediately. We'll explain the reason and work toward a resolution. If the closure was due to a policy violation, you have the option to appeal.

On the login page, click the "Forgot Password?" link. An OTP will be sent to your registered mobile number or email. Use it to set a new password. Your password should be at least 8 characters and include numbers and special characters.
💳 Payments & Transactions

21 winbd supports deposits via Mobile Pay, Nagad, Rocket, and DBBL Mobile Banking. Bank transfers and cryptocurrency are also accepted. All methods offer fast and secure transactions.

The minimum deposit is ৳200 and the minimum withdrawal is ৳500. To qualify for the welcome bonus, your first deposit must be at least ৳500. Maximum deposit and withdrawal limits depend on your account verification status.

Withdrawals are typically processed within 15–30 minutes of submitting a request. Mobile Pay and Nagad are usually the fastest. If KYC is incomplete, or for large first-time withdrawals, processing may take an additional 2–24 hours.

Deposits are usually reflected in your balance within 1–5 minutes. If it hasn't appeared, try refreshing the page. If the issue persists, contact live chat with a screenshot of the transaction. Providing the transaction ID will help speed up the resolution.

21 winbd does not charge any deposit fees. However, your mobile banking provider (such as Mobile Pay) may apply a small fee according to their own terms. There are no withdrawal fees charged by the platform either.

For security purposes, it's generally recommended to withdraw using the same method you used to deposit. Withdrawals via a different method are possible but may require additional verification. Visit the Payment page for more details.
🎁 Bonuses & Promotions Popular

A 100% welcome bonus is automatically credited on your first deposit after registration. The minimum deposit to qualify is ৳500. No promo code needed – the bonus goes straight to your bonus wallet.

A wagering requirement must be met before withdrawing bonus funds. Typically, you need to wager 10–20x the bonus amount — for example, a ৳1,000 bonus requires ৳10,000–20,000 in bets. Check the bonus page for specific terms.

Bet a set amount each week and earn a weekly cashback reward. Rates and terms may vary from week to week. Check the latest Promotions page for the current cashback offer.

When someone registers through your referral link and makes their first deposit, you earn a bonus. Referral bonus rates and terms are subject to change. Visit the Bonus page to see the current referral offer.

Every bonus has a set expiry period, typically 7–30 days. If the wagering requirement is not met within that time, the bonus will be automatically forfeited. Claim and use your bonus promptly, and make sure you're aware of the expiry date.
