To be honest it seems there is pretty good reason not to trust bets of bitcoin.
They declared a bet with hundreds of btc wagered as a draw when it was clear that BFL hadn't shipped any product. They claimed the bet terms were ambiguous, why was the bet accepted in the first place then?
I have also lost out on a decent amount of bitcoins on another bet that was made a draw, and although I didn't agree with the way they handled things, I can understand why they did it. You have to remember that they lose out on a lot of profit on these bets when they call it a draw.
Yes it is possible that they themselves were on the other side of the bet, but I think it is much more likely that now and then a bet was less clear than they thought it was, and they make it a draw if they feel that is the correct thing to do. It's harder than you think to make things unambiguous.
So they still have my trust.
