Yes, you can mine Ethereum with RTX 3060, but there are a few things to keep in mind. First, Ethereum mining is very demanding on the GPU and RTX 3060 is not the most powerful card on the market.
Second, Ethereum mining is a bit of a gamble. The price of Ethereum could go up or down, and if it goes down, you will have less profit or even lose money.
Another thing to consider is that mining Ethereum uses a lot of electricity. So, if you want to mine Ethereum with RTX 3060, make sure you have a good power supply and that your electricity costs are not too high.
Overall, mining Ethereum with RTX 3060 is possible, but there are a few things to keep in mind before you start.
