Only if the dollar entirely collapses and we all end up killing each other for a loaf of bread LOL. That's definitely "worst case scenario" - for the time-being at least :o|
More likely we will see the price of the US$ (and other currencies like the £ too of course) fall significantly in comparison with gold. So this means that gold will become a more valuable commodity, and therefore the PPS of stock that have real gold reserves either in the ground or above the ground will shoot up proportionately. So you'll get a lot of $$$ for your share in KATX.
If you cash out and have cash in hand then like you say with that days evaluation your money will worth nothing but if you stay invested in KATX or each time you sell some with that days value you convert it to gold your in good shape for example considering todays gold price and the pps when gold is 4500 in 5 years without adding any other value into the comp the pps will be much higher then what it is SO STAY INVESTED CASH IS WORTHLESS GOOD LUCK
