Someone like the function(claim or refund). That the players each put in their bets, and can refund them until the round is satisfied (either by meeting the number of players requirements or the amount of money in the “pot).
Once the “betting” round is over, the idea is there is a vote, and consensus of a certain threshold is needed in order to refund the money.
If no consensus is reached another round is played with the possibility of more players and equity added, and therefore a possible shift in ability to meet a consensus.
There could be the possibility to make side deals or to use smart contracts to make such deals.
Would be interesting to think about with an asset that could appreciate a little or a lot over a short or long period of time.
