You should buy gold bullion today if you want to earn more money because gold is the best investment as of the moment. Many investments today are losing because of world economic recession. Real estate is not gaining and in fact most of the houses owner could not pay their amortization. Stock market is also losing that many investors became poorer than before.
If you invest in gold most likely you earn more money because the gold price is climbing faster these past few years. If I have much money I would rather invest in gold today than real estate because you can sell the gold easily than real estate. Make a decision today and earn more money.
