PCB now has an official bank. Located at the new end of the market, the PCB Bank offers a place for players to deposit their money and earn interest. You can deposit a maximum of $10,000. Interest is calculated hourly and is at a rate of 1.00% a day. Your bank balance may exceed $10,000 but NO interest will be credited in this case. If the interest earned pushes your balance over $10,000, the interest will not be granted (so try to keep it at least $100 below $10,000).
Left click the signs to deposit and withdraw money and check your balance. See the rules in the bank for more details.
There is a player run bank next door which offers a higher savings rate. Use it at your own risk.
Happy savings!
