not quite sure I know how that works tbh its quite new to me this betting lark.
The term fold is just another word for "amount of accumulated bets". For example betting on a team to win is a 1 fold, betting on one team to win and another to also win is a two fold and so on.
If you lay a 5 fold and all the odds are 2/1, your return will be 2 x 2 x 2 x 2 x 2 = 32/1 plus your initial stake.
