I retorted that they are not the same. Gold is tangible. You can hold it in your hand. You know how much of it is being stored in vaults. Although the price certainly fluctuates, gold has been a store of value for thousands of years. It doesn't rust or corrode.
Gold became store of value because it had good properties for being such - great chemical resistance and some durability, so it can be stored without degrading, scarcity, so people won't have to deal with large quantities or risk their wealth being reduced by increasing supply, and lack of practical applications for it. Bitcoin also has many values that make it a good store of value - it's much more compact than gold, so it's easier to transfer and store it physically: a piece of paper, usb or cd drive are most commonly used, but any method for storing information works. You can even engrave your private key on a piece of gold to have a Bitcoin that "doesn't rust or corrode". Thanks to being digital Bitcoin is much faster and easier to move, meaning that Bitcoin can be used as a currency while gold is very impractical.
Its price is something borne of pure speculation.
Every price in the world is based on speculation, there's no such thing as intrinsic value, because value exists in human minds. Gold can easily become nearly worthless if in the future people will find even better store of value.
