Well A. Thats not a date and
B. When is it determined you win?
I win after each incorrect date passes. If the price passes $24777 I lose.
It's not complicated, really.
I think you don't get it. It's a Gödel theorem thing. If the price doesn't pass 24.777K you never win, since you have to wait forever to prove that you are right.
If bitcoin collapses you lose too, since it would meant that you were allowed to bet on an infinity numberof winning dates, that would be incorrect.
