Too late for gold.
You have to look at more than just inflation related data for the asset. Gold tends to be a inversely correlated to the economy because people use it safety asset. So right now, I think the gold prices are already inflated from people moving into it during the crash last year. Silver seems to have suffered a similar fate after the GME thing too. If you are looking at metals, it might be good to look at those positively correlated with the economy. After all, we will only see real inflation if the economy is doing well too. I like platinum, but got into that about 9 months ago. Copper would have been good too. I'm not sure if they still make sense at their current levels, but what do I know.
Crypto is not a real inflation hedge in my opinion. If you're hedging, it's not supposed to be highly speculative (on other factors). Crypto is much more likely to experience wild swings unrelated to inflation.
Real estate is an option, like raw land or maybe residential rentals. I say maybe for rentals because of all the coronavirus restrictions on collecting rent. I wouldn't be surprised if that sort of sentiment continues or expands in the future. I like raw land, but that depends on the area and other stuff. There's an increasing threat that raw land could be zoned conservation, removing it's potential future value (I won't get into the bigger conversation around that). The mortgage on your own house can be beneficial.
I plan to stay with mostly equities. There are a lot of options in there as far as sectors or industries. A materials or induatrials ETF could be good, but it would require more research to see how covid has affected supply/demand.
