Does anyone know when exactly ETH becomes PoS ?
And when it's happens what coin is good to replace in our mining rigs (especially with AMD Polaris GPUS) ?
No one really knows as the devs of Ethereum are well known in missing the deadlines they pone to do.Based on that I would say as a minimum can happen in late 2022 early 2023 so there is enough time to keep mining Ethereum and making money like all miners do.
Plenty of other coins to mine if Eth goes PoS and the top of them are,ERG,ETC and RVN.
According to the this post, the full switch to PoS is expected at Feb 2022.
4. We think ~4 months is a generous timeframe from having the code done to seeing the merge on mainnet.
5. We think there's a chance this can happy by February (obviously, still a lot of unknowns!), so we decided to set the bomb based on that.

As for the other coins, when ethereum mining stops, the 750Th/s are too much to be handled by all of the remaining coins put together. For example etc's nethash is 27Th/s and the other coins are several times lower than that. So, in order the mining to continue to be profitable, the price of the other coins will have to increase at least 25 times. Although possible in the long run, I can't see that highly probable in mid-term especially in short-term. So, the most probable outcome is that everyone who pays for the electricity to continue on a loss or to sell the gpus. This will quickly bring the prices of the current gpus below 500$. Like in 2020 at some point before the 5700's, amd 570's and 580's were priced around 200$ as new. And then the second hand gpus weren't too many. Now if these millions gpus are put on sale in ebay, the prices will go even lower. So, to calculate the current daily profit and extrapolate it one year from now is a big mistake. And the hope of selling a $4500 non gaming gpu for any price above $100 or a normal card for $2000 above $200 is another big mistake. So, it is better to invest directly in Bitcoin than hoping for ROI in the next one year. It is just a free advice to the newbies from a veteran miner since 2016. I have the choice now to use my rigs as heating devices through the winter, or to settle on a carribean island, enjoying my riches.
