There is no fair coefficient though , I wonder in case of two probabilities why the coefficient is not 2 average it is only 1.8 , the bet companies make a lot of money daily due to our eagerness and passion .That true , even I feel that , even with betting at 1.3x or less , there is lot of risk involved though we may think we can easily win from such low payouts. The match can turn anytime away making us lose the money.
