Seriously I believe that it is a business wear when you have the capital to go into it and the knowledge of how to exploit the business you would definitely keep making a decent amount of profit.Iron is very expensive nowadays. A few days ago, I went to inquire about the price of metal cap which is used for motorcycle petrol tanks. It was around $1.5-$2. It was made of iron or some sort of metal. I think this is why people who deal in iron or metal make good money because they can earn huge profits.
