you are right in that they will never GROW unless you can confirm a wager instantly especially in horse racing the waiting to see if it was taken "in time" or not raises questions to the actual person risking the money. its understandable that the person not risking the money would say its all in the system and the clocks and they dont choose which to take or not. but they dont put the money up first... will hinder growth. s
sill in the early phase of bitcoin books at least they are offering something unique here. I like it overall. but wonder how much they will actually be able to grow with no way to confirm wagers instantaly so you know one way or the other if your bet is in...
