This is wrong. Both people have, lets's use $100 as an example. Both put 20 in box, so both go down to $80. Person A sells Person B the box for $30, so person A ends with $110(profit!). But person B pays $30, bringing him down to $50, although there is $40 in the box, so it brings him back up to $90: $10 loss
End result: A has $110
B has $90
