I just noticed that Bitcoin's hash rate has dropped significantly. It turns out it's related to the situation in Iran, which has caused energy prices to spike. So when electricity costs rise sharply, mining becomes less profitable, and many miners are starting to shut down their operations.

If energy costs continue to increase, this could pose long-term pressure on Bitcoin network security. But on the other hand, it could also mean that mining concentration will shift, with miners who have access to cheap energy becoming more dominant. Interesting to watch how this will develop moving forward.
