As far as I can tell, the dissenters in this thread are either confused, exposed (i.e. shareholders), or bribed. There has been a lot of name calling, but there has not been one coherent argument as to why my bet should not be refunded.
Judging by the previous posts you also have regular BitBet users against you. Makes sense because people that bet later take less risk and dilute their winnings. The weighting of bets should kick in here, but it seems that's not enough so those users are fine with the policy as they regard late bettors as .
In my opinion it would be far better to have different closing criteria for bets. In this specific instance the bet could've been closed when the price crossed $7XX dollars at the reference exchange. By using TX confirmation times and trade data you can verify which bets were placed before closing. Of course that would be some more work, but it can be automatised. If the owner's really want to protect early bets from late bets, than something like this should be the way to go. But clearly, the current practise / policy is devious self-righteousness, to say the least.
