GPU mining profitability after ETH 2.0 (2022 update) What will happen to mining after Ethereum 2.0?

In this video I calculate what GPU mining profitability will be after Ethereum 2.0. But what will happen to mining after ETH 2.0? After Ethereum moves to Proof of Stake (POS), it will no longer be mineable on GPUs. When this happens, all of the people currently mining Ethereum will move their GPU hashrate over to the other mineable coins. But in doing so, the profitability of mining those coins will decrease. So I wanted to calculate by how much mining profitability will decrease after ETH 2.0. I do this by comparing the network hashrate currently on Ethereum with the hashrate currently on the other top 35 GPU mineable coins. I then convert the hashrate from Ethereum to the other coins to calculate what the mining profitability for all the other altcoins will look like after all the Ethereum hashrate moves to those coins.
