I've been playing for 18 days or so and whenever I win on fight list it seems everyone gives roughly the same amount of money. So what determines this, it doesn't seem to go off the money they have on hand and if that's the case what's the risk to walking around with a couple hundred billion if nobody ca steal it?
this is an interesting question. i've been playing for years, and i never really thought about it. i'd be curious to have some more information about this, even if we can't get the exact details.
There is really no need to use the bank and lose cash in deposit fees unless you are going for an achievement OR you are trying to brag and make sure people can see how much cash you have on the Leader Board. The amount taken per fight based on the typical players number of fights in any given day will not reach the amount lost in deposit fees even with an elite.
