Let's have some fun. I'll send 0.01 BTC to the winner.
Guess the price of 1 BTC in USD at noon EST November 3, 2018. We will use the NYSE index for the price. The smallest absolute difference wins.
The deadline for guessing is noon EST November 30, 2017.
Open to Hubski users with accounts created before 3 November 2017.
A fundamental problem with the wager is you are rewarded for offering higher estimates because the payoff is better but the loss is the same.
