I am new to this forum, and would like to hear some opinions regarding Ethereum  mining and Nvidia GPU, specifically:

1. When do you guys think Ether will move to POS? Is it by the end of the year?

2. Are miners still buying RTX GPUs today? If so, are they only buying the 3090s with no LHR?

3. Also on LHR, I know there are several software that claim they can unblock it and get back 70% of its power. But realistically how true is this?

Thanks for all the colors!
