There's no software developed yet to mine BTC with a gaming PC or even you mine altcoins;
Thats not true , you can still use some of the old Versions of Cgminer 3.7.2 and below or some speciall SgMiner Versions below Version 5.0 for mine Scrypt or SHA-256.
I still have some Versions of a few Miningsoftware Version where i have mined back in the Days around 2012 -2013 for Bitcoin and Litcoin with a GPU.
But yes i agree it will take 100 years for maybe getting something out of it
Mining with GPU's is no longer profitable since 2022, but there are still many people mining with GPUs and hoping for miracles.
It depends what you want to mine.
Hi, which is the most profitable crypto/software to mine with a gaming pc?
Energy is free in my case.
I would say that you should be buy the coins you want to mine before you start mining.
If you dont know the basics of how to use Miningsoftware and all that stuff you can damage your GPU and PC.
