Want to win 0.5 BTC? (Okay, I don't have much to give away, but this should be fairly simple).

All you have to do is guess a number between 0 and 100 (inclusive) by posting in this thread, then I will post HIGHER or LOWER.

Rules:

- Only 1 post/guess per member.
- MD5 of the number plus some other random things: e5c97082142b3d65ce55e5e36446577e (so you know I'm not cheating anyone and that the number has already been decided).

is it an integer?


Interesting game theory here. Normally with one person doing multiple tries you just want to guess in the middle each time. But here when we only get one shot we don't necessarily want to give more information to the next guesser. Although I guess there is no rational basis for us not too.

It becomes a question of how long we should wait until we make a guess. later guesses have a higher expected return but at the investiture of the time watching the thread and waiting for other people to take guesses. What if that cavalier first guesser gets it right on the first try?

Yes it's an integer.

One thing I didn't think about until after I'd already posted was that it seems people are holding back, waiting until near the end so that it's easier.

But the problem with that strategy is, there can be only one winner... first post will get it (I should have put that in the rules list).

So don't leave it too late to post a guess because someone else might post before you!

Edit: I think to help solve this issue next time, the prize money should gradually decrease... to give people more incentive to guess early.
