Making gold on Gaia is very time consuming.
You can't just play a game and expect to have 3mil in 10 minutes.
Don't waste your gold on anything. Save up, sell items. Make a quest forum. Good at drawing? Make an art shop. Join contests! There are plenty of contests forums in the
Charity/Quest forum. Play games such as booty grab, number one gold making game.
There is also buying a simple $10.00 cash card from a nearby store and buy a bundle.
Those sell for a lot. But that advice is only for those who are willing to waste '
REAL' money on pixels.
That's my advice if you want gold.
Hope it helped.
