I have a tenner in an old Betfair account. I've never used that website before and don't quite understand it!
I've pressed "lay" on a Labour majority, it says "your total liability on these bets: £640".
What exactly does that mean? If I lose I gotta pay that?
Probably a bad time to use Betfair for the first time, but I may as well use up my tenner!
Rep for any help!
