I guess they are desperate just like in 2018, in 2018, people were trying to use their celerons to mine eth ehhe
In 2018 or maybe 2017, I remember mining Zcoin (not Zcash) with my Celeron and Sempron processors. You guys probably don't remember but it was a CPU only coin at first and the way the algo was designed was that it didn't matter if you had a i7 or a single core celeron, your hash speed was the same.
So I was basically triple mining with my rigs back then. ETH was the main algo with GPU, dual mined DCR, and with the CPU mined Zcoin. I remember it was like $1-2/day per CPU and it was actually pretty profitable until people ruined it who rented like 10,000 AWS instances using free trials. Those sure were the days.
