Gold I think is a good benchmark. But really any forex asset is just as good or better for a comparison. Gold has some portion of its value derived from decorative uses and numismatic purposes. People don't put 100 dollar bills on necklaces or wear quarter pendants. If you hold Euros as an investment as an American (or vice versa with dollars) then this as an investment class is extremely similar to Bitcoin. Sovereign debt has similar characteristics but is subject to interest-rate based fluctuations to a greater dgree. The main difference is that the markets for foreign exchange are tightly regulated and trade with huge amounts of liquidity -- it is difficult to inconceivable for any entity to affect the price in any way useful for market manipulation (with some exceptions, like Soros's little game with the Pound).
