If you put price charts and hashrate charts together last time price was in $30k range hashrate was 114 on average and currently it is about 90 on average which is a 20% drop. Of course when price was $58k on average the hashrate was 140 on average which we shouldn't use in calculation for obvious reasons I mentioned above. But when you do you get 35% which is misleading.
Sorry, but
when was that?
Also, the fact you're using max price hash rate as an indicator of optimal profitability, that's misleading.
The hashrate from August till November last year was between 120-140Exa, with the price in the range of 9-13K, it would make zero sense for somebody that was mining at that time to turn of their gear now because of the slump in price.
We're still talking about 3x profitability compared to November at the same profitability as the second part of May when we reached 179.25 EH/s or the same as in February where we were also at 155.47 EH/s, while now we're moving towards 100EH/s not taking into account miners that have already moved, not considering constant gear delivery done by Bitmain since then, especially the May batch.
