WOW Gold training costs and personal spending.

While leveling a character from 1 to 85, a player naturally “creates” hundreds of gold,Archeology WOW Items, though much of it is “destroyed/spent” by repair costs, training costs and personal spending.

However, the amount of money “destroyed” also increases with age. Players obtain better gear which has higher repair cost.

Since a character starts with no money, it is clear that a perfectly new server has no money in circulation. As the server ages, money will be “created” at a greater rate, as players kill mobs (monsters) that drop more money and do quest with larger rewards.
