Odds serve two main purposes in sports betting:
Crypto sportsbooks calculate odds by analyzing a range of data and building in a margin to ensure long-term profit. Key factors include:
Shorter odds indicate a higher probability of success but offer lower returns. Longer odds reflect a lower chance of success but come with higher potential payouts.
For simplicity, all examples use USDT. The same math applies whether you’re betting with BTC, ETH, LTC, or even fiat currency.
Widely used on crypto sportsbooks with global user bases. Decimal odds show your total return per unit wagered (including your stake).
Example:
Odds of 2.50 mean you receive 2.50 USDT for every 1 USDT bet (includes your original stake).
Formula:
Profit = Stake × (Decimal Odds − 1)
Common in the U.S. and supported by many crypto sportsbooks.
Examples:
Formulas:
Common among UK sportsbooks, these odds show profit relative to stake.
Example:
Odds of 5/1 (“five to one”) mean you win 5 USDT for every 1 USDT wagered (total return: 6 USDT).
Formula:
Profit = Stake × (Numerator / Denominator)
Similar to decimal odds but only show profit, not the total return.
Example:
Odds of 1.50 mean you win 1.50 USDT for every 1 USDT bet. Total return = 2.50 USDT.
Formula:
Profit = Stake × HK Odds
Based on implied probability and similar to American odds, but expressed as decimals between -1.00 and +1.00.
Examples:
Similar to American odds, but in decimal format based on a 1.00 base.
Examples:
Once you understand how odds formats work, the next step is to calculate what they imply about the chance of an outcome happening. This is called implied probability. It’s the percentage chance that a bet would need to succeed for it to break even.
If your own estimate of success is higher than the implied probability, the bet may offer positive expected value.
Implied probability = 1 / Decimal Odds × 100
Denominator / (Denominator + Numerator) × 100
Suppose a crypto sportsbook offers odds of +150 on Team A.
To find the implied probability:
= 100 / (150 + 100) × 100
= 100 / 250 × 100
= 40%
If your own analysis suggests Team A has a 50% chance of winning, then the bet may represent good value. The sportsbook implies a 40% chance, but you believe it’s higher.
All odds formats express the same idea: how likely the sportsbook thinks an outcome is. The table below shows how each format corresponds to the same implied probability.
Implied Probability | Decimal Odds | American Odds | Fractional Odds | Hong Kong Odds | Malaysian Odds | Indonesian Odds |
95% | 1.05 | -1900 | 1/20 | 0.05 | -19.00 | -19.00 |
90% | 1.11 | -1000 | 1/10 | 0.11 | -10.00 | -10.00 |
80% | 1.25 | -400 | 1/4 | 0.25 | -4.00 | -4.00 |
66.7% | 1.50 | -200 | 1/2 | 0.50 | -2.00 | -2.00 |
50% | 2.00 | +100 | 1/1 (evens) | 1.00 | +1.00 | +1.00 |
40% | 2.50 | +150 | 3/2 | 1.50 | +0.67 | +1.50 |
33.3% | 3.00 | +200 | 2/1 | 2.00 | +0.50 | +2.00 |
25% | 4.00 | +300 | 3/1 | 3.00 | +0.33 | +3.00 |
10% | 10.00 | +900 | 9/1 | 9.00 | +0.11 | +9.00 |
5% | 20.00 | +1900 | 19/1 | 19.00 | +0.05 | +19.00 |
