Odds are the foundation of sports betting. They determine how much you can win, reflect the implied probability of an outcome, and shape your entire betting strategy. Yet many bettors, especially newcomers, find odds confusing. Understanding them is essential to making informed decisions and maximizing your profits.
This guide explains everything you need to know about sports betting odds on crypto sportsbooks. We will cover the different formats, how to calculate implied probability, and how to identify value bets. For more betting insights and guides, visit bgfutbol.com.

What Are Betting Odds?
At their core, odds represent two things:
-
The Probability of an Outcome: They indicate how likely an event is to happen. A team with very low odds (e.g., 1.10) is heavily favored to win. A team with high odds (e.g., 10.00) is a major underdog.
-
The Payout: They determine how much you will win if your bet is successful.
The Three Main Odds Formats
Crypto sportsbooks typically offer odds in three formats: decimal, fractional, and moneyline (American). While the platform may display odds in your preferred format, it is helpful to understand all three.
Decimal Odds
Decimal odds are the most common format on crypto sportsbooks and are widely used in Europe, Canada, and Australia. They are simple to understand.
Example: 2.50
How to Read: For every 1 unit you stake, you will receive 2.50 units back if you win. This includes your original stake.
Calculating Your Return: Stake × Decimal Odds = Total Return
Example: If you bet 10 USDT at odds of 2.50, your total return would be 10 × 2.50 = 25 USDT. This includes your 10 USDT stake and 15 USDT profit.
Calculating Implied Probability: (1 / Decimal Odds) × 100 = Implied Probability (%)
Example: 1 / 2.50 = 0.40 × 100 = 40%
Fractional Odds
Fractional odds are traditional in the UK and Ireland. They are expressed as a fraction, such as 5/1 (five-to-one) or 10/3.
Example: 5/1 (five-to-one)
How to Read: For every 1 unit you stake, you will win 5 units in profit. Your stake is returned separately.
Calculating Your Profit: (Numerator / Denominator) × Stake = Profit
Example: If you bet 10 USDT at odds of 5/1, your profit would be (5 / 1) × 10 = 50 USDT. Your total return would be 60 USDT (50 profit + 10 stake).
Calculating Implied Probability: Denominator / (Numerator + Denominator) × 100 = Implied Probability (%)
Example: 5/1 odds: 1 / (5 + 1) = 1 / 6 = 0.166 × 100 = 16.6%
Moneyline (American) Odds
Moneyline odds are primarily used in the United States. They are expressed as either a positive or negative number.
Positive Odds (e.g., +200):
-
How to Read: Indicates the underdog. It shows how much profit you would make on a 100 unit stake.
-
Example: +200 means you would win 200 units in profit on a 100 unit stake. Your total return would be 300 units (200 profit + 100 stake).
Negative Odds (e.g., -150):
-
How to Read: Indicates the favorite. It shows how much you need to stake to win 100 units in profit.
-
Example: -150 means you need to stake 150 units to win 100 units in profit. Your total return would be 250 units (100 profit + 150 stake).
Calculating Implied Probability:
-
Positive Odds: 100 / (Odds + 100) × 100 = Implied Probability (%)
-
Negative Odds: (-Odds) / (-Odds + 100) × 100 = Implied Probability (%)
Example: +200: 100 / (200 + 100) = 100 / 300 = 0.333 × 100 = 33.3%
Example: -150: 150 / (150 + 100) = 150 / 250 = 0.60 × 100 = 60%
Why Understanding Implied Probability Matters
The implied probability is the bookmaker’s assessment of the likelihood of an outcome. However, the total implied probability across all outcomes in an event will always exceed 100%. This overround, or vig, is how the bookmaker makes a profit.
Example of the Overround
In a football match with three outcomes (Home Win, Draw, Away Win), the odds might be:
-
Home: 2.00 (Implied Probability: 50%)
-
Draw: 3.50 (Implied Probability: 28.6%)
-
Away: 4.00 (Implied Probability: 25%)
Total Implied Probability: 50 + 28.6 + 25 = 103.6%
This 3.6% is the bookmaker’s margin. The lower the overround, the better the value for the bettor.
Identifying Value Bets
A value bet occurs when you believe the actual probability of an outcome is higher than the implied probability suggested by the odds.
The Value Betting Formula
Value = (Your Estimated Probability × Decimal Odds) – 1
If the result is greater than 0, you have found a value bet.
Example of a Value Bet
You estimate a team has a 60% chance of winning. The bookmaker offers odds of 2.00, which implies a 50% probability.
Value = (0.60 × 2.00) – 1 = 1.20 – 1 = 0.20
This is a positive value bet. Over the long term, betting on such outcomes should be profitable, provided your probability estimates are accurate.
Crypto Odds and the Market
Crypto sportsbooks often offer more competitive odds than traditional bookmakers. Lower operating costs allow them to offer lower overrounds, which translates to better value for you. Additionally, the crypto market can sometimes react more slowly to news, creating opportunities for sharp bettors to find value before the odds adjust.
Common Odds Mistakes
Ignoring Value
Many bettors bet on their favorite team regardless of the odds. Focus on finding value, not just backing teams you support.
Misunderstanding Probability
Do not confuse implied probability with actual probability. Understand that the bookmaker’s odds include a margin.
Betting Based on Emotion
Emotion clouds judgment. Base your bets on analysis and value, not on loyalty or recent frustration.
Not Comparing Odds
Different crypto sportsbooks may offer slightly different odds on the same event. Compare odds to ensure you are getting the best possible price.
Overlooking Market Moves
Large moves in the odds can indicate significant money has been placed on a specific outcome. This can be a signal to reassess your own view.
Using Odds in Your Betting Strategy
Bankroll Management
Use the implied probability to assess the risk of a bet and adjust your stake size accordingly. A low-probability bet (high odds) should have a smaller stake than a high-probability bet.
Hedging
If you have a pre-match bet and the live odds shift, you can use the live odds to place a hedge bet. This can lock in a profit or reduce a potential loss.
Arbitrage
Arbitrage involves placing bets on all outcomes of an event across different bookmakers to guarantee a profit, regardless of the result. This is rare and requires quickly identifying discrepancies in the odds.
Who Benefits Most From Understanding Odds
-
New Bettors: Understanding odds is the first step to making informed bets.
-
Strategic Bettors: Understanding value and probability is essential for a long-term profitable betting strategy.
-
Analytical Bettors: Players who enjoy analyzing data and probabilities will find understanding odds natural.
-
Crypto Bettors: The competitive odds on crypto platforms offer more opportunities for value.
Final Verdict
Understanding betting odds is essential for any serious bettor. Whether you use decimal, fractional, or moneyline odds, the underlying principles are the same. Focus on understanding implied probability and identifying value bets.
Crypto sportsbooks often offer more competitive odds, making them an attractive option for value-focused bettors. The speed and efficiency of crypto also allow for quick reactions to market changes. However, the fundamentals of odds reading and value betting remain the same regardless of the platform.
