Some sports work better with specific odds formats. For instance, American sports tend to work best with American odds, which are handy for spread betting. Horse racing works better when fractional odds are used. For most other sporting events – including football – decimal odds are the preferred format. American odds can tell you what you need to bet to win $100 or what a $100 bet will get you with a successful bet. Fractional odds tell you what you can win (the left figure) when you wager the amount shown (the right figure), while decimal odds reveal the amount you will win with a single €1/£1/$1 bet. Naturally, these are adjusted into cryptocurrencies when you play with BTC sportsbooks.
