Not sure about that. But in the long run, it probably would serve as a hedge against depreciating currencies. In the event of worldwide economic crisis, gold may take a hit at first -- commodity shock -- but it would likely perform well against most asset classes IMO in the aftermath. And who knows? Maybe the long term bull run continues.....

To the OP, I'd choose bitcoin. It's pretty clear it's not going away at this point. Decentralized, divisible, transferable value. It's an amazing thing.
