Any new Silver is very hard to find these days, I am very positive to see a huge price increase in silver, that's why I am holding the physical stuff. There are a couple of services that offer storage for gold, silver and platinum.
The paper silver is not backed by the physical silver, so if you want to ever let yourself be paid out the physical from the paer silver there is a chance that if everybody does it you will not be getting your physical silver, and will make the price of the paper silver drop to 0.
Make sure to get it stored in Switzerland or any country that doesn't let your own government take the stuff away from you, just incase a war breaks out or w/e.
