well the idea is simple!

local banks take 10% of the amount deposited for protection and security perpose
federal bank takes 15% for the "World Wide" servide in addition to protection and security.

any comments?

How would you fit this in with the role play aspect of the game and taking into account the era the game is set in?

i dont really like this idea because from a role play aspect you wouldn't even use a bank as it would be "too risky" because you dont want you or your family going to jail because on suspecion of something like crime because you have alot of money and no legit job for it.

Actually, It fitts perfectly!

you bribe the bank to keep quiet about your cash and you pay him back 10 / 15 % as a reward!

Actually I think a more suitable idea for RP is to bribe the airport inspectors and send the money out to Switzerland. But that would be incredibly hard to code i think. But I doubt many Successful bosses put their money on other peoples banks. because after they deposit the money the bank has the boss by the balls, :S and I'd prefer not to have my balls broken for a measely 1 mil :P

Well the local banks already have a charge for transfering from city to city, so I'd leave that is, but yeah, a flat 15% laundering fee for depositing into a Federal bank without drawing suspicion from the FBN would be a logical addition.
