I am looking to invest in gold but I am not sure how to make profit from it...Can anyone explain to me? Example I go open an Public Gold account then I buy 5 grams as it is the minimum. 5 grams cost 177.4900 for today right? So how do I make profit? Must I wait the buying to rise? Example the buying price is now 180.0000 so if i sell it all i earn around rm 3 from each grams? Please help me
