Gold

it is currency for World of Dragoncraft

Method of Acquiring
The valued currency of Sword Art Online is gathered swiftly from boss battles, as they yield a large amount of valuable loot, but the loot is usually shared among all participants of the boss battle. Other methods of acquiring Gold include killing monsters in dungeons or open fields, selling fruit that drop from trees (not a very efficient method, but it is favored by those who refuse to battle monsters), trading, Monster PK, and for orange guilds and players, ambushing other players and stealing their items and money in exchange for their lives.

high level players can get 1 LE per hour

Inflation
Because the value of one Gold is based on the drop rate maintained by the Cardinal System which is kept constant at all times, neither inflation nor depreciation ever occur in Aincrad.[4] To ensure that the value of Gold is maintained, items are sold to Non-Player Characters (NPCs) at fixed market prices.

Gold
Gold are the base currency of World of Dragoncraft. Gold are a common drop from mobs and are found abundantly in Loot Chests and the Daily Reward chest. They are also gained through trading, breaking pots, completing dungeons, completing quests and converting Gold Blocks.

Gold Blocks
An Gold Block is made of 100 emeralds. The way they are usually obtained is through Emerald Merchants in banks; they compress 100 emeralds into one block. Blocks can also be acquired through trading, completing quests and converting Liquid Emeralds into blocks.

Liquid Golds
Liquid Gold are the highest denomination of currency in World of Dragoncraft. Liquid Golds are obtained by converting 100 emerald blocks with the Liquid Emerald .Because liquid emeralds are created using so many Gold, people sell extremely rare or powerful items for them.
