Bitcoin Mining Difficulty Drops 10% as Miners Operate at a Loss

Bitcoin mining difficulty dropped 10.09% — from 138.9 to 124.9 trillion — the second-largest decline of 2026 and the lowest level since July 2025, The Block reports.

What "difficulty" actually means: it's a measure of how hard it is for the network's computers to find the right number to add a new block. The network automatically lowers difficulty when there are fewer miners active, so blocks keep arriving roughly every 10 minutes no matter how much hardware is currently running.

The reason behind the drop is economics, not technology: bitcoin has now traded below its estimated production cost of roughly $78,000 for five straight months, and around 20% of miners are currently operating at a loss, Yahoo Finance reports. Revenue per terahash of computing power has fallen to a record low of $0.028 a day. Some miners are responding by simply switching off unprofitable machines.

What this means in practice: a difficulty drop isn't the network breaking, it's a built-in self-adjustment mechanism. But for the industry, it's a direct signal: at bitcoin's current price, mining on outdated or electricity-hungry hardware simply doesn't pay for itself anymore.
