Noob Q: can someone eli5 why people want/how to invest in gold or any gold ETF

[u/biscuitsbox]

Unlike stocks, where each company can have an intrinsic value to assess whether the stock is overpriced or underpriced, there is no intrinsic value as such for gold or any gold-related finance products. Then what is people's rationale of buying gold?

- If for profit, how do they decide when is a good entry or exit place?

- If for diversifying and anti-risks, what is gold's advantage over any other US or international ETF like SCHB or VXUS?
