Gold ETCs. What is the difference?

Looking to buy gold as a small % of my portfolio. Do not hold any now, and did not buy any during the previous year's gold rush. So buying for diversification - not speculation. Looking at gold ETCs, and I see that 4GLD has a TER of 0.00%, but people say that it is misleading. The performance of all of them seems very similar. JustETF comparison page is also not very helpful https://www.justetf.com/en/how-to/gold-etfs.html What should I be looking for? submitted by /u/monitorius1 [link] [comment
