DepositsYou can allow players to deposit their money to your bank. You are also able to set the interest their deposits will have, up to 1%. The interest is added to the deposited amount daily. Players can withdraw deposits at any time, granted that the bank has enough cash for that.
LoansPlayers can apply for a loan from your bank. When a loan application arrives, you should investigate the player in various ways to ensure that they are trustable enough to lend to. You will be able to define a daily interest and a daily installment amount, which the player must then accept for the loan to be given out.
Note that if a player cannot afford your loan or dies, you will lose the money you have lent out!
