The other side of this misconception: "The hash rate will crash." Lots of people believe that if the average cost to mine a bitcoin becomes greater than the price, hash rate must drop to account for it.
The truth is that not all miners have the same cost -- not by a long shot. The industry is increasingly moving towards efficient grid use that allows for extremely low energy costs. Here is one example. Mining efficiency also plays a major role. Smaller miners with higher electricity costs and those running inefficient miners like S9s are shutting down, but more efficient operations are also coming online.
Since the halving about 32 hours ago, the network has seen one block every 10.38 minutes. That's slightly below the target time and the previous rate, but certainly doesn't indicate the 30-35% drop predicted by BitMEX Research or many other hash rate pessimists.
Thank you. I also wanted to touch this but I still have a little understanding about mining related topics. With what you said, am I right to assume that this is not just a beginner's misconception? It seems that some more experienced or knowledgeable investors have different opinions on this.
The hashrate did drop but not directly because of the halving. It's more likely an effect caused by the reduced mining rewards and the leaving of less efficient miners.
