I think you mean Bitcoin is portable, whereas Gold is not. That's one of the key advantages of Bitcoin. You can store it within the smallest medium possible, hidden in plain sight. Millions, if not, billions of dollars can be moved anywhere in a safe and discreet way. You can't do that with Gold. Carrying bulky bars and/or Gold coins will bring unwanted attention.
Not only Bitcoin is portable, but its supply is predictable too. No one knows how much Gold is in existence, but everybody knows there will only be 21m Bitcoins. This predictability should make BTC even scarcer and more desirable than Gold. With "Wall Street" quickly flocking to Bitcoin, you can see what the craze is all about. I'd keep buying BTC regardless of price to build true, generational wealth.
Yeah, portability and predictable supply are huge benefits to Bitcoin. Compared to gold, which must be stored in the case and carried around very carefully, Bitcoin allows you to carry millions of dollars in a wallet where no one can notice. History has demonstrated that gold has a long term value and that Bitcoin has a fixed 21 million limit that makes it a special digital asset.
I think a mixture of both will serve to diversify various risks digital to be flexible, gold to be stable. Only one thing to remember, security is paramount, a lost seed phrase is lost forever.
