The least complicated answer is :
Just Buy Gold ETFs like Kotak Gold, Goldbees, or Reliance Gold. The beauty of these ETFs is that you can invest in them like buying and selling regular equity stocks, can store them in your demat, and their value appreciates/depreciates as per the bullion market prices.
It can be beneficial if you can find a difference in pricing. Sometimes these ETFs are available at a discount, and thats when you can strike it rich.
