Account Login
How to Log In to 399btc
Logging in to your 399btc account takes just a few seconds. Here is the complete step-by-step process, whether you are accessing from a desktop browser in Dhaka or opening the site on your phone in Chittagong.
Navigate to the 399btc Login page using the link in the site's main navigation. The login page loads on any modern browser — Chrome, Firefox, Safari, or the built-in browser on your Android or iOS device.
Type your registered username or mobile number in the first field, then enter your password. Both fields are case-sensitive. If you registered with your Bangladeshi mobile number (e.g., 017xx or 018xx), use that exact number as your identifier.
If you have two-factor authentication enabled on your 399btc account, you will be prompted to enter a one-time code after submitting your password. The code is sent via SMS to your registered mobile number or generated by your authenticator app.
Once authenticated, you land on your 399btc account dashboard. From here you can navigate to the game lobby, visit the cashier to deposit or withdraw, check your bonus balance, or contact live support — all from a single screen.
Registering a New 399btc Account
Before you can use the 399btc Login page, you need to create an account. Registration at 399btc is free and typically takes under two minutes to complete. The process is entirely in English and is designed to be straightforward for new players across Bangladesh, whether you are in Sylhet, Khulna, Rajshahi, or Cox's Bazar.
During registration, you will be asked to provide a mobile number, choose a username, and set a password. Your mobile number serves as your primary identifier and is used for account recovery and two-factor authentication. Use an active Bangladeshi number that you have regular access to — losing access to this number can complicate account recovery later.
After creating your account, a basic KYC (Know Your Customer) verification step is required before your first withdrawal. This typically involves submitting a copy of your National ID card (NID) or passport. KYC review usually completes within a few hours. You can deposit and play immediately after registration — KYC is only checked at withdrawal time.
A valid Bangladeshi mobile number (Grameenphone, Robi, Banglalink, Teletalk, or Airtel), a chosen username (6–20 characters), a strong password (minimum 8 characters, mixed case and numbers recommended), and confirmation that you are 18 years or older. No email address is required for basic registration, though adding one is recommended for additional account recovery options.
399btc accepts the following documents for identity verification: Bangladesh National Identity Card (NID), passport, or driving licence. Documents must be valid (not expired) and the name must match the payment method you intend to use. A clear photo or scan of the front and back of the NID is sufficient for most players.
New 399btc accounts are eligible for the welcome bonus on the first qualifying deposit. The offer is applied automatically after your first bKash or Nagad deposit meets the minimum threshold. Check the current promotions section inside your account after logging in for the exact bonus amount and wagering requirements that apply to your account.
Password Reset & Account Recovery
Locked out of your 399btc account? Here is how to recover access quickly without contacting support in most cases.
Click "Forgot password?" on the 399btc Login page and enter your registered mobile number. A one-time reset code is sent via SMS to that number. Enter the code on the next screen, then set a new password. This process takes about 60 seconds and works for most Bangladesh players using Grameenphone, Robi, or Banglalink numbers.
If you added an email address to your 399btc account during or after registration, you can also request a password reset link by email. The link expires after 30 minutes. Check your spam or junk folder if the email does not arrive within a few minutes. Gmail and Yahoo Mail addresses both work reliably for this purpose.
If you no longer have access to your registered mobile number or email address, contact 399btc support via live chat. The support team will ask you to verify your identity using KYC information on file before resetting your credentials. This process typically takes 15–30 minutes during business hours (BST, UTC+6).
Security Features & Two-Factor Authentication
Account security is a priority at 399btc. The platform uses industry-standard SSL (TLS 1.3) encryption on every page and every transaction, meaning all data transmitted between your device and 399btc servers is protected from interception. This applies whether you are logging in from a home WiFi connection in Mirpur, Dhaka or using mobile data in Sylhet.
Two-factor authentication (2FA) is available on all 399btc accounts and is strongly recommended. When 2FA is enabled, anyone who tries to log in to your account must have both your password and access to your registered mobile phone. Even if your password is compromised in a data breach elsewhere, your 399btc account remains secure because the attacker cannot complete the 2FA step without your phone.
399btc also monitors login activity for unusual patterns — for example, a login from a new device or a location significantly different from your usual access point may trigger an additional verification step. You will receive an SMS alert on your registered number in these cases. If you receive an unexpected alert that you did not initiate, contact support immediately via live chat.
Go to Account Settings after logging in, select "Security", and click "Enable Two-Factor Authentication". Choose SMS verification (recommended for Bangladesh users) or app-based verification using Google Authenticator or Authy. Follow the on-screen prompts to link your mobile number or scan the QR code with your authenticator app. Once enabled, 2FA applies on every future login.
After completing a successful 2FA login, you can mark your device as trusted for 30 days. On a trusted device, you can log in with just your username and password without repeating the 2FA step every time. Only mark your own personal phone or home computer as trusted — never a shared or public device.
399btc sends an SMS notification each time a successful login is made to your account from a new or unrecognised device. If you receive this alert and did not initiate the login, change your password immediately and contact support via live chat. The 399btc security team can freeze your account within minutes if suspicious activity is reported.
Making Your First Deposit After Logging In
Once you have logged in to your 399btc account, making a deposit is the next step. Here is how the cashier works for Bangladesh players using bKash, Nagad, and other local payment methods.
After logging in to 399btc, click the "Cashier" or "Deposit" button in your account dashboard. The cashier section lists all available payment methods supported for your account region (Bangladesh).
Choose bKash, Nagad, Rocket, or Upay as your deposit method. These four mobile banking options are the fastest and most widely used by 399btc players in Dhaka, Chittagong, and across Bangladesh. Bank transfer options are also available for larger amounts.
Type the amount you wish to deposit in BDT. The minimum deposit is ৳200 for bKash and Nagad. There is no maximum deposit limit for standard verified accounts. The amount will be shown in your 399btc balance immediately after the transaction is confirmed.
A payment prompt is sent to your bKash or Nagad app. Open your mobile banking app, approve the transaction with your PIN, and the deposit is confirmed. Funds appear in your 399btc account balance instantly — no waiting, no manual approval required on the 399btc side.
