Introduction
Odds are the foundation of sports betting, determining both the potential payout and the implied probability of an outcome. Whether you’re new to sports betting or transitioning to a crypto sportsbook like bet105, understanding how odds work is essential for making informed bets.
Crypto sportsbooks operate similarly to traditional sportsbooks but offer unique advantages such as faster transactions, enhanced privacy, and access to sharper odds. This guide provides a comprehensive breakdown of how betting odds function, the different odds formats, how to calculate probability from odds, and how bettors can leverage this knowledge to maximize returns.
How Sports Betting Odds Work
Odds represent the likelihood of a particular outcome occurring in a sporting event. They also dictate how much a bettor stands to win relative to their stake. Betting odds are set by sportsbooks based on statistical models, market trends, and public perception. Sharp bettors analyze odds to identify value bets—wagers where the implied probability differs from the actual likelihood of an event occurring.
At crypto sportsbooks like bet105, odds are often more favorable due to lower operational costs and reduced juice (the built-in commission that sportsbooks take from bets). This allows bettors to extract greater value from their wagers compared to traditional sportsbooks.
Types of Betting Odds
Sportsbooks display odds in different formats depending on the bettor’s region and preference. The three most common formats are American, decimal, and fractional odds.
American Odds
American odds, also known as moneyline odds, are commonly used in the United States. They are expressed as positive or negative numbers.
- Negative odds (-110, -150, etc.) indicate how much you need to bet to win $100. For example, odds of -150 mean you must wager $150 to win $100 in profit.
- Positive odds (+200, +300, etc.) indicate how much profit you earn on a $100 bet. For example, odds of +200 mean a $100 bet returns $200 in profit.
Decimal Odds
Decimal odds are widely used in Europe, Canada, and Australia. They represent the total payout per unit wagered, including the initial stake.
The formula for calculating winnings:
Winnings = Stake × Decimal Odds
For example, if you bet 1 BTC at odds of 2.50, your total payout would be 2.50 BTC (1 BTC × 2.50), meaning a profit of 1.50 BTC.
Fractional Odds
Fractional odds are most common in the UK and horse racing. They are displayed as fractions, such as 5/1 or 7/2.
- A 5/1 bet means you win 5 BTC for every 1 BTC wagered.
- A 7/2 bet means you win 7 BTC for every 2 BTC wagered.
While fractional odds are less common in crypto sports betting, understanding them is still useful for comparing odds across different sportsbooks.
Converting Odds to Implied Probability
Implied probability helps bettors determine if a wager has value. It represents the sportsbook’s estimation of how likely an event is to occur.
The formulas for converting odds to probability:
- American odds (positive): 100 / (Odds + 100) × 100
- American odds (negative): Odds / (Odds + 100) × 100
- Decimal odds: (1 / Decimal Odds) × 100
- Fractional odds: Denominator / (Denominator + Numerator) × 100
For example, if a team has decimal odds of 2.50, the implied probability is:
(1 / 2.50) × 100 = 40%
If your own research suggests the team’s true probability of winning is 50%, then this bet has positive expected value (+EV), making it a smart wager.
Finding Value in Crypto Sports Betting Odds
The key to successful betting is finding odds that offer value. A value bet occurs when the implied probability of an event (based on the odds) is lower than the actual probability determined by your analysis.
Example of a Value Bet
A team has American odds of +200, meaning an implied probability of 33.33% (100 / (200 + 100) × 100). If your analysis suggests the team has a 40% chance of winning, this is a +EV bet. Over time, placing bets with a positive expected value leads to long-term profitability.
bet105 offers sharper odds than traditional sportsbooks, increasing the likelihood of finding +EV opportunities. Since crypto sportsbooks operate with fewer overhead costs, they often provide better lines and reduced juice, maximizing bettor profits.
