as you can check around, I'm focused on network security (difficulty) regression
because decreasing security will erode Store-of-Value (purchasing power of Bitcoin) , what is advertised as the one of most impotant Bitcoin features/properties...
And potential other consequences - like for example if there is only 25% of network hashrate of the past ATH, and rest 75% of ASIC hardware is idle and ready to use, who knows if not in a malicious way - that's only another, additional consequence here.
