Hi this is my first post

This is a question I have where I wonder how bad it is that I bought an alt with ETH then decide to sell it for BTC. I get confused about how to think about or track the ROI which I'm mainly interested in trading relative to BTC prices. (And that's not even considering fiat!)
My overall strategy is hodl and stack BTC but I am also long on ETH and started trading ETH/BTC on occasion.
I tried searching for an answer but couldn't find one so I hope you don't mind sharing your votes and comments if you have any. Looking forward to learning from you. Thanks!
