Whenever a question comes up while using bt399, this page is your best destination. Detailed answers on four important topics are organized here — from keeping your account secure and depositing via bKash or Nagad, to understanding VIP cashback and tips for uninterrupted mobile play. Every answer is written in plain language so you can make quick decisions and play with confidence.
Stay Safe
Never. No bt399 employee or support team member will ever ask for your OTP, bKash PIN, Nagad PIN, or bank password. If anyone asks for this information — by phone, message, or email — it is a fraud attempt. Stop the conversation immediately and report it to our support team. Never sharing your financial details with anyone is your best protection.
Create a strong password that combines uppercase and lowercase letters, numbers, and special characters (@, #, !). Use a password that is at least 10–12 characters long. Use this password only for bt399 — do not use the same password on any other site. Avoid simple words or your date of birth as a password. Changing your password every few months adds an extra layer of security.
Yes. bt399 protects all your data through SSL encryption. This means your name, phone number, and payment details all reach the server in an encrypted state. Your information is never sold or shared with any third party. For more details, please read our privacy policy page.
Fraudsters sometimes create fake sites that look like bt399. To identify the real site, always check the address bar in your browser for the bt399.bar domain. Verify that the HTTPS lock icon is present. Instead of clicking an unknown link to log in, type the address directly. Domains with slight spelling differences (such as bt-399.bar or bt399.com) are suspicious.
If you see a transaction you did not make, or your password is not working, contact our 24/7 live chat immediately or send an email to [email protected]. At the same time, change your bKash and Nagad PINs. Taking quick action can reduce any potential damage.
VIP & Cashback
bt399 gives cashback at a set rate based on your total bets for the week. This cashback is credited directly to your account and can be used in your next session. The higher your VIP level, the higher your cashback rate. The calculation is done at the end of the weekly cycle, so playing regularly increases your benefit.
bt399 has three VIP levels:
Bronze — up to 0.3% cashback per week.
Silver — up to 0.7% cashback per week.
Gold — up to 1.0% cashback per week.
At every level, cashback is calculated on a weekly basis and added to your account automatically.
Bronze — up to 0.3% cashback per week.
Silver — up to 0.7% cashback per week.
Gold — up to 1.0% cashback per week.
At every level, cashback is calculated on a weekly basis and added to your account automatically.
Betting regularly and consistently raises your VIP level. The more active you are, the sooner you get the chance to move up from Bronze to Silver, and from Silver to Gold. bt399 monitors your activity and automatically upgrades eligible members to a higher level. Check your account dashboard to see your current status.
Gold VIP members enjoy the highest weekly cashback and get priority on withdrawals. There are also opportunities to receive exclusive bonus offers on special occasions and access dedicated support. bt399 always gives special attention to Gold members.
Once you receive cashback, it is added to your account balance. When withdrawal conditions are met, this amount can be withdrawn. To learn more about the specific terms, visit our terms and conditions page or ask in live chat. The minimum withdrawal amount is ৳500.
Deposit Questions
First, log in to bt399 and go to the cashier or deposit section. From there, select Nagad. Send the payment to the number shown using the Nagad app or by dialing *167#. The minimum deposit amount is ৳500. Save your transaction ID — you can show it to support if any issue arises. In most cases, your balance updates within a few minutes.
bt399 currently accepts deposits through four methods: bKash, Nagad, Rocket and bank transfer (including Dutch-Bangla Bank, Islami Bank, BRAC Bank, and other banks). The minimum deposit amount for each method is ৳500. These methods can be used easily from anywhere in Bangladesh.
Log in to your bt399 account, then go to the cashier section and select bKash. You will see the payment number — use "Pay" or "Send Money" from the bKash app. The deposit amount must be at least ৳500. Enter the reference number correctly when making the payment — this helps the funds get credited faster.
In most cases, it takes a few minutes for the balance to update. Wait a moment and refresh the page. If it still does not appear, contact live chat with your bKash / Nagad transaction ID and a screenshot of the payment, or send them to [email protected]. Our team will verify and resolve it quickly.
bt399 itself does not charge any deposit fee. However, your mobile banking provider (such as bKash or Nagad) may apply their own transaction charges — these can vary depending on the terms of that service. Bank-specific policies also apply for bank transfers. Contact your service provider for specific details.
Playing on Mobile
Yes, bt399 is fully mobile-friendly. The site works easily on Chrome, Firefox, or Safari on any Android or iOS smartphone. No separate app download is needed. The full features of the site are available on mobile — games, deposits, withdrawals, live chat, everything.
On Android, open bt399.bar in Chrome, then tap the three-dot menu at the top right and select "Add to Home screen". On iPhone, tap the share icon at the bottom in Safari and select "Add to Home Screen". After that, bt399 can be opened directly from the home screen just like an app.
Once your connection is restored, refresh the page and log in again — your account balance is kept safe on the server. Game round results are determined from the server, so a fair outcome is guaranteed even if you lose connection. If you notice any discrepancy, report it to live chat immediately.
First, clear your browser cache. In Chrome, go to Settings → Privacy → "Clear browsing data" and delete the cache and cookies. Then reload the page fresh. If the problem continues, try switching between Wi-Fi and your data connection. If that does not help either, let us know in live chat — our team will assist you.
bt399 is designed to keep load as light as possible. However, live dealer games or video-based games may use comparatively more data. Using Wi-Fi gives you the best experience. Keep an eye on your data package when playing on mobile data.
