Account-relatedBankroll management guide
Proper money management is essential for playing responsibly. Following the guidelines below will make your gaming experience more enjoyable and controlled.
Set a gaming budget
First decide the maximum amount you will spend on gaming each month. Make sure this limit does not affect your essential expenses, rent, or savings. Only use money you can afford to lose.
Divide by session
Break your monthly budget into smaller sessions by week or day. For example, if your monthly budget is ৳5,000, allocate ৳1,250 per week. It is wise not to spend the entire budget in a single day.
The 1–5% rule per bet
Do not stake more than 1% to 5% of your session bankroll on a single bet. Following this rule means that even after several consecutive losses, you still have a chance to recover before your entire balance is gone.
Decide to stop after a win
Set a specific winning target — for example, stop when you have made a 50% profit on your session bankroll. Playing longer out of greed may give back your winnings.
Respect your loss limit and keep records
If your session bankroll drops by 30–50%, stop for the day. Record the outcome of every session in a notebook or app. Looking back at your history will help you understand where you are losing the most or which games you are winning.
Beware of fake sites and scams
- Verify the correct domain: Always make sure t678.lat is shown in your browser and that there is an HTTPS connection (green padlock icon). Fake sites often use similar-looking names.
- Do not share your OTP or PIN: t678's support team will never ask for your bKash PIN, Nagad PIN, or OTP. Whoever asks — it is a scam.
- Keep your password private: None of our agents or support representatives will ever ask for your account password.
- Beware of "agents" on Telegram and Facebook: People offering "recharge" or "bonus" deals in the name of t678 on social media may be fraudsters. Only transact through the official site.
- What to do if you are scammed: Immediately change your account password, call bKash/Nagad customer care, and notify us through our live chat support.
