The graphs of Bitcoin and gold are too similar and this can be an indicative for Bitcoin to boom like gold in the future. And I believe that Bitcoin will overtake gold in 10-15 years from now.
Obviously the market share is different between gold and bitcoin, charts cannot determine that there are similarities. from the price movement alone is very different between bitcoin and gold.
bitcoin will still become a new market share besides gold, and they will move on their own and will not influence or take over each other.
