Using the old rule is much clearer and fairer for everyone in my opinion.
What was the old rule?
The "old" rule is in fact still in vigor. We are currently considering changing it,
hence this thread.
The rule in question is described here:
https://bitbet.us/faq/#1121In short, it states that bets received (where "receives" means "transaction is included in a block")
after betting closes or after the resolution event occurs will be considered "donations" to BitBet.
I remember people talking about this. The best policy is not to honor the bet and refund it. Considering it a donation is wrong, as clearly it was intended to be a bet. If you start allowing the bets you'll open up yourself to being scammed.
