<prompt> Human: Im slightly intrigued by the idea of investing in gold, but how easy would it actually be to liquidate it and get your moneys worth at a later time? Obviously youre not gonna pay directly with gold at the grocery store or anything like that.EDIT: So I shouldve clarified, I meant buying gold as a way to preserve wealth, rather than actually make new money, as you would with stocksbonds. I looked at some gold ETFs, but they all have expense ratios. This is fine for stocks, but the idea is that gold will hold the same value over time relative to the dollar. So if theyre annually taking away some of your holdings, you are losing a little bit of value over time.  <response>: At a high enough temperature they will both melt
