Gold is measured in weight, while Bitcoin, much like currency, is an abstract form of money and can only be measured in units of itself. One Bitcoin is worth a lot more than 1 gram of gold, but a lot less than 1 tonne. Despite Bitcoin's stellar performance in 2016, the size and depth of the cryptocurrency market is dwarfed by the $7 trillion gold market.

Gold remains the only true global money with a size and volatility comparable to that of fiat currency.

Bitcoin – or cryptocurrency itself – is the most exciting monetary experiment in modern times.

Unlike fiat currency, it can't just be printed, and it mimics the scarcity properties of gold in that it needs an enormous amount of energy to create one coin. The energy-proof of value is what links gold to the primary industries and allows it to maintain its purchasing power over incredibly long periods of time. Without it, any form of money will inevitably be corrupted over time and decay. Bitcoin has some of the same energy-proof of value that makes gold far superior to fiat currency, which can be created with the stroke of a key. Bitcoin, also like gold, is a global currency that may be universally accepted in the future. Even USD can't make that claim.
