Possibly. But if you were to be buying and selling you would probly have to Amass a good Heap of Silver before you started. And you would always want to have lots extra so in a way you are holding a large portion and are just recycling the silver you have and sell when it goes up. Remember You only need a small profit. Making $2 on 100 Ounces makes you $200 which can buy you about another 10 ounces free and if you continue this eventually you will be making alot but it will take time and great knowledge of the market to Fund a life with a Family.
