If we dont see a continued rise in price or at least some sort of continued support above the 40k level as more and more institutions and businesses like HUT8 and Bitfarms continue to expand wouldnt difficulty just crush out the little guys with one or two older ASICs? Then add in what would happen if the majority of China did come back online?  At what point do we need to see a significant increase in price to offset what could be a very large change in difficulty?
