Haha - thanks! This was the most clear "improvement suggestion" I have seen so far. We will care for it soon.

Another short notice: We really would like to accept 0 conf transactions and we know that other sport bet sites do this. However - it is to easy to double spend a 0 conf transaction.

So we really thing sooner or later someone will attack sportbet sites with 0 confs. There might be some payment channel solutions that will allow 0 confs in the future - and than we will of course allow it but for now it is our prediction that the other sport bet sites will get into trouble with 0 confs and disable them soon.
