Gold practically has no use except for to accessorize. IMO, gold is not such a good investment unlike many believe it to be. Back when there were not much to invest in, gold was probably one of the few options to choose from. Plus considering the fact that it was used as a medium for exchange, people must have saved up on it because of it's increasing value. But I bet it had increasing value then because of its use, but now since it's not used as much nor is it as rare to find, it may not make much of a good investment nor will it's value increase as significantly as before
You obviously miss the whole point of gold
Gold is a very specific investment, if investing in it can be called an investment at all. People are typically investing in something (say, Bitcoin) to make their money grow. But this is not the case with gold and if you are looking to multiply your wealth, gold is an enormously wrong choice (read, you should look elsewhere). Gold is a store of value and it should be considered as such only, i.e. as a store of value and not as a vehicle for multiplying it
Gold is like silence, it is hard to refute it
