I'm wondering as to weather there will be interest implemented in to banks. As the amount put out on loans is very high then the banks have got to be earning plenty from them.
Another option I came up with may be to have exact values per month instead of percentages, for example, instead of getting 2 percent interest, the bank just gives a flat amount of gold to everyone.
So for example if Mr K had 10 million and Mr X had 500k
Bank A offers 1.2% interest and Bank B offers a flat 50k gold
Therefore Mr K would earn 120k from Bank A and 50k from bank B
Whereas Mr X would earn 6k from bank A and 50k from bank B
Obviously you would nee a certain amount in the bank to define weather you are eligible to get the 50k from Bank B, that would most probably be defined by the bank owner
For those who don't understand what interest is, it works by you having money in the bank and the bank giving you a little bit extra money for free because you use their bank. Obviously it is variable from bank to banks as owners decide the amount they want to give you.
