$20 from a complete retard more like, gold prices have shot down the quickest I have ever seen in a game, you won't be able to sell gold for $20 anywhere, unless to someone incredibly gullable and possibly slightly mentally handicapped.
Highly possible as little as 4 days ago though, then again 10 days ago you could sell for $30/m to bulk buyers letalone private, hopefully gold doesn't go down much further.
Gold will definitely bottom out around 1-2$ per mil.
