1,648,531 GH/s is the current target. I can bet below or above that. It maybe sound odd, because I am not really into the Bitcoins, but what (in the very uncertain case) if the target is hit (neither below or above)?
But in all seriousness, if that does happen, we'll refund all the bets without taking any house fees.
Anyway, cool site, great idea and thx for the links above!
