How to Read Odds
Understanding odds is the most important part of betting. Being able to read odds correctly lets you know your potential winnings in advance.
Decimal Odds Example
You place a bet of ৳500 at odds of 1.80.
Total return = ৳500 × 1.80 = ৳900
That means your profit is ৳400 (after subtracting the original ৳500).
Implied Probability
Odds of 1.80 mean the probability of winning is approximately 55.6%. Formula: 1 ÷ odds × 100.
Fractional and American
Fractional: 4/5 = 1.80 decimal. American: -125 ≈ 1.80. 520db uses decimal odds.
Account Verification Process
Why is KYC Required?
Identity verification is mandatory to ensure legal compliance and the security of your account. It also helps prevent fraud and money laundering.
What documents are required?
National ID (NID) or passport, proof of address (electricity bill or bank statement), and a selfie photo.
Processing Time
Verification is usually completed within 1 to 24 hours. It may take a little longer during busy periods.
