Currency

Underground Evolution has two main currencies, Money and Gold.

Money

Getting money is relatively "easy" in U-E. You can obtain this by being very active in crimes, going to work, stock market, etc. This is the main way of trading in the shops and with other players.

Gold

Even though gold is not a rare currency, it is much more valuable and harder to obtain than money. Some crimes and work will give you gold, but in much smaller quantities than money. The better items will have a money and gold price. Another way of obtaining gold is by becoming a VIP.
