It's already too late unless you can get RTX 2080 Ti for 250$, if this doesn't happen it's better to stay away from mining and this is even after you've calculated your electricity expenses first, in some countries mining sucks right now.
RTX 2080 Ti are very hot graphics cards and are inferior in terms of profit to GeForce RTX 3060 Ti. Now it is better to buy video cards with lower power consumption and DDR6 memory, which does not heat up during mining, so as not to be spent on additional ventilation and more powerful power supplies.
I'd buy a RTX 2080ti over a RTX 3060 Ti I just like that graphic card, it's like an Asic miner made in heaven lol, imagine having 8 2080Ti in a rig, this will set me up for 2025, may we all live to see more than 2025, amen.
