I've been stacking Silver and Gold for quite a few years now. Not only is it a forced form of saving but physical precious metals can be anonymous as well. As far as changing my life goes, that will happen soon when I get to retirement with my secret stash that should increase in value nicely! And to top it off, if I didn't have Silver or Gold then I wouldn't have Stax The Hotty Botty upvoting my posts!
Oh, I almost forgot, I think I've upvoted every single @silvergoldbotty post since inception so the next 7 days is locked in.
