Ugh.. Trendon Shavers, I remember many people pointed out that this has got to be some kind of ponzi scam. Yet there were flame wars going between supporters of the scheme and more skeptical people. Not the best time in the Bitcointalk community. Yes, I do have an account from late 2012, but I am not login that in until Theymos implements some kind of 2FA or Google login. Too many people lost their accounts to hacks recently.
There's no shame in Bitcoinland.
https://bitcointalksearch.org/topic/m.18382142Wow, I didn't know that even Finney's account was hacked. Now I have to be more careful about various old accounts starting to posting again after all these years, lest they be some doppelgangers.
As for gold price, the "flow" matters more than "stock", since gold has a massive 190K ton stock, that's like 6 billion ounces, almost enough for 1 gold coin per population on this planet. So you look at how much Indian demand are for this year and how many mines are going shut down or come online based on spot price and how much they hedged, etc. Investment demand didn't have that much of an impact until like 12 years ago (unless you want to go back to 70's).
The main problem with gold price (besides manipulation through derivatives) is the "scrap" or recycled supply whenever price spike. Since gold has HUGE stock in the wild, when price spike, some people are going to haul in their hoard (jewelry and heirloom) and exchange them for cash. Like this Japanese man who recently got robbed in the middle of Ginza, which is like the most upscale and prosperous area in Tokyo,

So it's reasonable to expect the BTC/Gold ratio to get bigger and bigger overtime since BTC does have less of an overhang in supply (e.g. whales waiting to dump).
