Let's say you join a give away with other user and both have to select a number between 1 and 10, you go for 7 while he goes for 9. The winning number is 8.
If the prize is 0.1BTC what would you do? Split the prize and walk away with 0.05 or Reroll to gamble for the full prize?
I am confused, would you mind elaborating? I mean, why would they split the price when none of them chose the winning number? wouldn't they have to do a reroll by default since no one won? was there a rule stating that if no one picked the winning number then whichever number is closest to the winning number will win? then, if so, picking to split the prize is a great choice but if the participants cannot change the number they have picked then, I'd go for a reroll since I picked 7 and have more chance of winning than the other guy who picked 9.
I think the matter is simple, it is a kind of gift, so the point is that you leave with something or you leave with nothing, a betting paradox from the social point of view, based on the free bet, then socially you criticize the who loses by not dividing. The conditions can be varied but specifically it is about that, dividing the prize, yes or no.
Let's forget the social stigma, let's bet:
In my case, since it is free, that is, I understand the $0 buyin, the decision does not it should not change if your buy is $1 or whatever the corresponding amount is, the decision is always based on your chances of winning, so you should take the first positive option that results.
Scenarios:

0.1BTC, if I win. /
