Bitcoin’s mining difficulty is edging closer to record territory as the network heads toward its first adjustment of 2026. Data shows difficulty reached roughly 148.2 trillion in late December and is projected to rise further in early January as block times remain slightly faster than the 10-minute target.
The increase follows a turbulent year for miners marked by rising energy costs, heavy capital requirements, and sharp market swings. Higher difficulty raises the computational effort required to earn block rewards, squeezing margins for operators already under pressure from volatile bitcoin prices and declining transaction fees.
Despite the strain, regular difficulty adjustments remain central to Bitcoin’s design, helping maintain network security and decentralization. The continued rise in difficulty highlights the growing amount of computing power securing the blockchain, even as competition intensifies and industry consolidation accelerates among less efficient miners.
