Coming back to Bitcoin, there is a question of magnitude. Because Bitcoin is a micro-economy, any adoption will cause its growth to be much greater than gold; that means the time-frame will be compressed - it's possible to see 100 years of gold's growth in 100 weeks. In addition, similar patterns are occurring at the same time - makes sense because of the functional equivalency between gold and Bitcoin. That accelerated, exponential growth would also occur synchronously in a hypothetical stock exchange 1% the size of NASDAQ, as long as the two work in a similar fashion.
One thing to keep in mind is that Bitcoin is mostly growing as a transactional medium right now, rather than a store of value like gold is today. The former is relatively unknown while the latter is familiar to everyone and has been for thousands of years. Bitcoin supply is also growing at ~25% annually; gold supply increases at ~1.5% per year. These are the factors that introduce some divergence, but they're still similar enough to be highly correlated.

Gold is a very mature 'product' to trade in whereas bitcoin is very young and still finding its place in the world. The real value will not be realized until further on down the line. Its difficult to gain a foresight by extrapolation of historical prices.
