Its 1907 again and You will be like your grandparents who kept money in their mattresses.

I am 53 and was old enough as a kid to hear "Old People" talk about their first hand experiences during the Great Depression of the 1930's. My grandparents and great grandparents kept money hidden in their mattresses because they had been through multiple "bank runs" and lost everything. I remember thinking how silly this was. With whats happened in the last year, and whats still happening with crypto exchanges, they were 100% right about not trusting centralized institutions.

EDIT: My point being that hiding and holding cash like my grandparents did in 1907 and the 1930's is like US pulling our bitcoin Off the exchanges and using hardware wallets.
