And there are so many conclusions that after halving crypto mining has become unprofitable, so then one can ask why someone buys such a large amount of mining equipment outside of China? It is more than obvious that the buyer thinks that the investment will pay off regardless of the reduced reward, electricity prices, taxes, labor costs and so on.
If you go to mining section of this forum and read posts from 2011 you will see that miners keep complaining how unprofitable mining is. But they keep mining. I think they just want to avoid more competition and simply try to convince new possible miners to start mining.
