I have been hearing a song called "Ethereum will switch to POS algorithm" for many years
Yes, if I follow the tips of people, I would never bought my cards and never won the money of mining in 2017, and we are in 2020, still mining ETH profitable
ETH will likely do the transition next year or even 2022
And about Claymore, with the new cards of Nvidia and AMD with RDNA2, he'll probably make an update to these new cards at the end of the year, but don't forget, that are a couple of miners of ETH like Phoenix.
