So the highest difficulty we had was 88.10T, using the previous halving data, I calculated that we would drop a minimum of 15%, which puts us at 74.88T, the lowest we did so far is 79.49T, I still think we have a room to the downside, regardless, obviously, if we make a new ATH either in price or difficulty, then the 75T theory is out the window, however, I don't see either of these things happening this year.
By chance I was going to ask what the ATH of the hash was.
Really, in the current scenario, I think it will be difficult to return to these values. Unless the super large mining companies continue to significantly increase their farms. Honestly, I don't think so, as there is no indication that the price of BTC will start to rise sharply.
