I've a sudden idea. What happens if facebook decides to issue Silver Libra, each unit is backed by 1 ounce of physical silver? 1 Silver Libra silver dollar = $16.20 + 1% premium at current price?
How many do you think he can sell? I think he can easily sell 100 million units of Silver Libras, assuming he actually has 100 million ounces of silver in a warehouse.
If Silver Libras are fixed at 100 million units, how will he handle the situation if the demand exceeds supply and people start to bid Silver Libras so that each Silver Libra is worth more than the market price of an ounce of silver?
