So the solution to this whole vbookie thing is to not quote odds before the fight. This will encourage people to bet on who they think will win more so than chasing odds. Of course you could still assess what the odds would be as well by looking at the relative amounts bet on each fighter.
This way a fighters odds will be determined by the opinions of fellow MMAForum members and credits will retain their "value" somewhat ie; vbookie will not have a credit creating/reducing effect. After a fight the odds can be calculated and assigned to the winning bets.
What do you guys think?
