Subject: Re: OT mostly: forevers
My long term concern is that US dollar may not be reserve currency of the world. Gold price more than doubled in the past two years is an indication the world is looking for alternative.

I wouldn't lose all that much sleep over it. What matters is the purchasing power of the currency, not how many things it's used for. In the general case the USD might hold its value but fade as a reserve/trade currency, or vice versa. More specifically, what matters is the purchasing power of your portfolio, which also might not be tied to your home currency's trajectory even if everything is listed there.
