Gold can be held, yes. It also is expensive to verify, transport, and protect. This has proved problematic for holders of the past. A paper system had to be built on top of Gold, which severely diluted the value proposition as gold was confiscated and stockpiled centrally. Practically speaking, very few individuals hold gold and the utility of doing so is limited when you consider how liquidity in the gold market functions.
Bitcoin is a different beast. You hold the cryptographic keys (like a password) which let you move Bitcoin to someone else’s address (under their password). You don’t trust anyone: Bitcoin is verified by math, not humans. It is tangible in the same way that owning google.com is tangible (and unarguably valuable). Bits and bytes exist on a global network and only you can move them.
When compared to Gold, Bitcoin is interesting because it is highly transportable, easily divisible, and censorship resistant. Consider this: Bitcoin let’s you store $1T USD of dollars in your head, transport it anywhere in the world, and there’s not a single thing anyone else can do about it.
