There is no correct sides in any game only correct prices to strike a bet.
Two bettors bet on a coin toss ten times
Player A bets heads at 11/10 and wins all ten bets
Player B bets tails at 10/11 and loses all ten bets
Players A is 0-10 and minus 10 units
Player B is 10-0 and plus 9.09 units
Player A would be proclaimed a hero on this forum and Player B would be ridiculed.
