American odds display your return relative to a baseline of $100 DAI.
If there is a minus (-) symbol, you need to bet that amount to win $100 DAI.
Example: If you bet $120 DAI on odds of -120, it would return $220 DAI if you win ($120 bet + $100 in profit).
If there is a plus (+) symbol, you win that amount for every $100 DAI you bet.
Example: If you bet $100 DAI on odds of +120, it would return $220 DAI if you win ($100 bet + $120 in profit).
