There are many ways to invest in silver but if the economy
does crash in the US then there will be a rush to the banks
and people will try to take out their funds. This will cause panic
and the banks will simply close their doors. If you are keeping
your wealth stored in a safety deposit box at the bank, you will not be able to
access it.
The best way to store silver is to take physical possession and keep it with you
at home in a safe. When the crisis starts, there's going to be chaos.
