Trouble using WhatToMine for hobby mining

I have a halfway decent rig (5950x and 6900xt) at home that's unused as I'm out of the country long term. I was thinking of repurposing it to try mining some altcoins. I'm not expecting to get rich, but it would be cool to make a little profit after electricity costs, and most importantly I think I'd enjoy it as a hobby. I can SSH in while I'm away and tweak it easily too. I was using ChatGPT (4o) to do some calculations, and was pretty thrilled to see I could make a few $ mining KAS and ERG. I then found the site WhatToMine, but I think I'm doing something wrong. It's showing net profit in the negative for every coin. I tried putting in a 4090 instead of my 6900xt, same thing. At $0.14/kWh, the best I can do apparently is ALEO, losing -$0.01. I did notice that it doesn't seem to include a lot of altcoins, but it does have ERG, claiming a -$0.91 loss. ChatGPT spits out this: "The **daily net profit** for a **6900 XT mining Ergo (ERG)** at **$0.14/kWh** is approximately **$3.56/day**.​" Am I overlooking anything in WhatToMine, or should I just move on to another hobby (even if I went out and bought 2x4090's, which apparently will lose money too)? If it helps, here's how I have it set up currently (6900xt + 4090 as I was thinking of getting a 4090): https://preview.redd.it/lym9gtd8v3ie1.png?width=2291&format=png&auto=webp&s=5d3e78c52ccaffce921d37c328f7368f5e547df2
