What type of money will this use?
We call it simply ''Coins''.
What can we use it for?
To buy thing's for your character, like dragons, weapons, etc.
How will I know how much do I have
Well, you see, in this category, you will be able to see a post called: Inventory, where you
will see a list of all members registered with their current money, items, etc.. Ofc. you will start
with 500$ which will be enough to buy something to start with.
So, how do I gain more money?
To get more money there are many ways. You can sell your own items. Or fight. Everykill you get 100$. Ofcourse, for making sure you don't go and do lies, you must first have the fight approved and watched by a moderator, etc.

I guess that clear's up things.
