I wrote to my brother-in-law about it once in the context of running it by him, letting him vet it for me rather than trying to convince him. He's more of a stock guy, an aggressive investor. (Turns out he's aggressive in general and has gone of the deep end, so if I ever stop posting here you should assume he wiped me out with the rest of my family. Ahem). He was turned off by a perceived limited upside.

+1. I talk about the individual assets with certain friends and it seems that gold bugs can't be reigned in while non-gold investors are very hesitant about taking the plunge. I don't want to get someone into gold and then hear regular complaints about it not going up. "Are we there yet?" I hear that enough on this forum, haha.
And, dare I say it, I'm not fully convinced myself.

If I were, I'd go full pp. I'm quite content having the "money I cannot afford to lose" in the pp. But, like a lot of people, I feel a strong compulsion to throw a lot of money into stocks just as soon as it crashes again. (I know, know. You don't need to tell me).
