There is truth in what you say. But not only investing in gold, but all types of investments must know how to invest properly if you don't want to fail or lose. Gold investment is a real investment, the wrong way to invest can be a loss, let alone investing in crypto.
Gold investment can also be done digitally now, not only manually by storing a lot of gold in your safe, because in this technological era everything has made it easier for anyone to invest even though the knowledge to use it is also needed.
