Convenience
Gold Backed Currencies (GBC) or Digital Gold Currencies (DGC) are a lot easier and safer to trade than physical Gold. In fact, DGC's offer the best of both worlds, as they can be bought, sold or exchanged in any quantity from any computer connected to the Internet, any time, anywhere in the world.

Actual Gold
Unlike options and other gold derivatives, DGC's are a set quantity of physical, stored, allocated physical Gold bars and bullions.
However, unlike Gold bars, coins or bullions, which can only be traded for the whole bar, coin, or bullion price, thanks to DGC's, physical Gold can be bought in any dollar amount, as the amount of Gold traded is in fact the exact weight equivalent (in grams and milligrams) of the dollar amount purchased at the time the trade takes place. Therefore, accumulating physical Gold in any quantities at a time is not at all a problem. Likewise, selling Gold can happen for any quantity, anytime, anywhere.

Cost
It is cheaper to buy Gold through AnyGoldNow than buying Gold coins or bullions.

Safety
Safety of the DGC is not an issue to the individual investor, as the Gold bars backing your gold are kept in vaults for you. Storage fees for DGC's are also minimal (1/12th of 1% per Month or less).

Mobility
Mobility of assets is paramount. With DGC's you can buy Gold from one place and sell it at any other, for any currency. You can even redeem your DGC to physical Gold and have it delivered to you in bars, coins or bullions anywhere you want !

Privacy
Privacy is an other very important issue as well : «Digital Gold» can be traded anonymously as DGC's have very strict privacy policies.
