What portfolio tracker are you talking about?
It's on the title - coinmarketcap portfolio.
@OP I haven't used this portfolio tracker and I only check it for the prices because there are other trackers that you can use. Before the most popular was blockfolio but AFAIK FTX have acquired it and we knew what happened to FTX.
Am I overlooking some functionality or is there another portfolio tracker that performs better?
I like to see my portfolio in ledger live.

I also use Ledger live and it's one of the best trackers that I've ever used although that's the main require, to own a ledger wallet first.
