I have a favorite number. It's a number that is in some sense "interesting", so it's feasible for people to guess. (Though 

.) Note that my definition of "number" for the purposes of this market is very loose, so it might include things you wouldn't normally consider to be numbers.

Each user gets to ask one YES or NO question about my favorite number, which I will answer honestly.

If their question was "is it [number]?" and the answer is yes, then I'll manalink that person M$50 and resolve the market to YES. Otherwise it resolves NO at the beginning of February.

(Any questions attempting to use this to divine other information, such as "is the first digit of your favorite number the same as the first digit of your credit card number?" will be disqualified. Any questions that are too hard for me to answer are also invalid.)

(There's no 20-question limit, that's just the traditional name of this game. It's one question per user.)
