If hillary loses the nomination, Alex can still delay paying off the bet by saying she still has a chance to win, even though it is next to none.
Alex will you agree that hillary must win the nomination -- even if she miraculously wins without it, you still lose the bet?
$20 is a plenty enough bet for us, but I think Alex wants more action. How about $1 million?
I was thinking, since Alex's prediction is a better sales tool for his super-iching products, he can put out a press release such as this:
"I ALEX CHIU BET YOU $1MILLION THAT HILLARY CLINTON WILL WIN THE ELECTION.
Pre-order Alex's Super-I-CHING book. If Hillary loses, I, Alex, will send it to you free, plus $100 (limit of first 10,000 challengers). If Hillary wins as I predict, then you must pay regular purchase price. Either way you will get Alex's amazing book."
This wil surely generate a lot of interest in Alex and will guarantee 10,000 copies sold if he is correct.
