I'm sorry to ask this, what is Mattress Bank?
I'm so happy you asked.
After all the bank failures in 1929, some very smart investors figured out the safest place to store their money - Mattress Bank.
After the gold confiscation in 1933, more smart investors figured out the safest place to store their precious metals - Mattress Bank.
Are you worried that something that became popular in 1929 has no reason to still be appealing today? Consider the great Cyprus Bank Robbery of 2013. The theft of funds from accounts was not done by masked bandits. It was done by the government of Cyprus.
Then consider that many governments worldwide have reserved the right to do the same thing.
Although many people have never heard of it, Mattress Bank has more branches than any other bank in the world. Mattress Bank accepts deposits of any currency, any precious metal, and anything else of value you wish to keep safe from economic collapse, social disorder, or government confiscation.
Personally, I sleep much more soundly at night - right on top of my local branch of Mattress Bank. Of course, the gold and silver bullion do make it a bit lumpy.
