Gold and silver are a stable currency, it will always be in price, but bank deposits are not so safe. Cash can be depreciated.
Gold and silver are precious metals and can also appreciate and depreciate in value. Bank deposits are definitely safe if they are FDIC insured and you have less than $250,000 in your account. However, it is always good to diversify your wealth in bank deposits, stocks/bonds, and precious metals. Out of all of those investments PMs are definitely the safest since they have a physical value to them that will always be attractive to people. I diversify my wealth to all those places and have recently began buying silver. This is the place I use, they offer me the smallest premiums out of all the dealers I have researched
