Just let them suffer. That's how miners become more experienced for next time.

What's going to happen with PoS is a lot like what happened in late 2018, when profitability on all coins declined by 90%. Miners like myself went bankrupt and liquidated their rigs for dirt cheap. Mining profit did recover 3 months later, though.

But this time, the crash will be 95%, not 90%; and it'll happen in a matter of days instead of months. I can't wait! It'll be an interesting time. My prediction: the average AMD GPU price will fall to 40% of MSRP, while NVIDIA will reach 60% of MSRP.
