I have 150 kilos of gold/silver too... and a store of food to last at least 3 years (still adding to that one) and a sufficient supply of arms/ammo to try to protect it.
The money i'm trading QID's in is in IRA's and I'm a year from being old enough to start taking it out without penalty... and when that day hits it will all be in my pocket and converted also to gold/silver. I'm hoping (but not expecting) that they keep the house of cards from collapsing until I can get it out. I'll take the penalty if it starts looking like it's coming unglued. But if we get to that point... odds are it's toilet paper anyway.
It's insurance but not confident that it will really matter when it all comes home to roost.
