Bitcoin is being put in the same category as gold because they're similar in a way that both can't be mass printed by will, as how the central banks can do with fiat money. But it definitely doesn't necessarily mean that bitcoin is 100% similar to gold because they're obviously not the same.
The specific characters of the two are also very different.
Bitcoin has a unique and technological sophistication that is equivalent to gold so that some people call it digital gold which is equal in value to real gold.
Bitcoin as an investment that has good potential in digital form, Bitcoin also has a good future.
