Gold and silver are store of values same way fiat is a store of value, but the pros of storing value in Gold and silver is stability the value of Gold and silver is much more stable than fiat so it may be better to store value in Gold or silver (PS: this is not a financial advice it's just my opinion).
Its true, gold and silver a good store of value but its not flexible like bitcoin. Gold and silver can not compare with fiat because fiat money always inflated on the value. I am believe gold and silver is good long term investment and its already know for centuries
