It is hard to say. It depends on the need for energy, the cost for energy, the price of bitcoin, the cost to make the ASIC (which is probably going to be the same in a year, but anyway) etc. And even with those figures, it's hard to make an approach. We've seen bitcoin doing a -85%, and increase its hashrate back in 2018. We've also seen it reaching ATH with -70% in price this year, comparably to November 2021 when it was valuated at $68k.
