– Answer:
To calculate the expected value of a crypto bet, multiply the probability of winning by the potential profit, then subtract the probability of losing multiplied by the potential loss. A positive result indicates a potentially profitable bet, while a negative result suggests it’s best to avoid the bet.
– Detailed answer:
Calculating the expected value of a crypto bet helps you determine whether a bet is worth making in the long run. Here’s how to do it step-by-step:
• Determine the probability of winning: This is usually expressed as a percentage or decimal (e.g., 40% or 0.4).
• Calculate your potential profit: This is the amount you’d win if your bet is successful.
• Determine the probability of losing: This is simply 100% minus the probability of winning (e.g., if the probability of winning is 40%, the probability of losing is 60%).
• Calculate your potential loss: This is typically the amount you’re betting.
• Use the formula: Expected Value = (Probability of Winning × Potential Profit) – (Probability of Losing × Potential Loss)
If the result is positive, the bet has a positive expected value, meaning it’s potentially profitable in the long run. If it’s negative, it’s best to avoid the bet.
Remember that expected value is a long-term concept. Even bets with positive expected values can result in losses in the short term due to variance.
Also, keep in mind that in crypto betting, odds and probabilities can be highly volatile and difficult to estimate accurately. Always do thorough research and consider market conditions before placing any bets.
– Examples:
Let’s look at two example scenarios:
Example 1:
You’re betting on a crypto coin flip with the following conditions:
• Probability of winning: 50% (0.5)
• Potential profit: 100 USDT
• Probability of losing: 50% (0.5)
• Potential loss (your bet): 95 USDT
Expected Value = (0.5 × 100) – (0.5 × 95) = 50 – 47.5 = 2.5 USDT
This bet has a positive expected value of 2.5 USDT, suggesting it could be profitable in the long run.
Example 2:
You’re betting on a crypto prediction market that a certain altcoin will increase by 10% in the next week:
• Probability of winning (based on your research): 30% (0.3)
• Potential profit: 200 USDT
• Probability of losing: 70% (0.7)
• Potential loss (your bet): 100 USDT
Expected Value = (0.3 × 200) – (0.7 × 100) = 60 – 70 = -10 USDT
This bet has a negative expected value of -10 USDT, suggesting it’s not a good bet in the long run.
