The total amount bought and sold in USD should appear in the profile info. I was misled and thought that I spent only $300 total in atomic hub, when in actuality I spent much more since the price of wax dropped. This USD amount can possibly appear right under the current "Total Bought" and "Total Sold" location in smaller text.

I'd say this is very important, since users don't look at the total wax bought, but the USD amount instead.

The total amount that I spent in USD at the moment of purchase is still under each NFT, so it shouldn't be hard to retrieve that data and sum it up.
