gold investment

How much is gold nowadays? Have you tried to invest in gold? How long should you wait before you sell your gold? How much does it usually appreciate over the years? How do you trade gold? How do you find someone to sell your gold to? I know I have lots of questions. But I really want to know more about investing in gold before I buy gold bullion. It entails a lot of money. I’m not sure yet how much I’m willing to invest since they say it takes a lot of time before you earn big from this. I don’t know if I can afford my money to be tied for so long.
