My suggestion is that when you die you lose a set amount (or percent or random drop) of money and if it was another player they gain that amount of the money dropped.

The amount would be set in the config as a simple number

The percentage would be set in the config as a simple number

The random amount would be set in the config as two numbers, max and min, these are the highest and lowest possible amounts of money that the random dropper picks
