The amount miners are earning in terms of fiat is down, and the cost of electricity and other energy is up, so it's hardly surprising that they are selling more bitcoin than before to cover their expenses. That's just basic math.
The sharp drop in Hash Rate shows that bitcoin mining is currently unprofitable.
Well, that's just nonsense. Zoom out on the chart. The "sharp drop" in hash rate is taking us back to levels we haven't seen since... *checks notes* last month! 180 EH/s to 80 EH/s when China banned mining was a "sharp drop". 220 EH/s to 213 EH/s is barely a fluctuation. At the last retarget the difficult only dropped by 2%.
A small number of miners with the highest electricity costs have stopped mining at the moment, or maybe moved to some other coin, but to suggest mining is "currently unprofitable" is just nonsense. Even if it were, and we did actually see a sharp drop in hash rate, then the lower difficulty which accompanied that would then make mining profitable again. It's a self correcting system.
