I looked into the golf rules with fiat books. All would have paid the player in full. The only reduction occurs in the tied players for 5th. I'm not sure why any of the bitcoin books are doing it differently but it's nice to see that DirectBet puts up rules so that no future problems occur.
I also like most of rules by Directbet but have one problem and this happen many time with me I bet and as I send payment and looking for confirming bet odds going very badly down why even some time happen event is not started yet why this difference
