Bitcoin’s network hashrate has entered a sustained downtrend, according to Twenty One Capital CEO Rapha Zagury, who characterized the move as the first bear market for the metric. The shift comes as mining operators increasingly compete with artificial intelligence (AI) and high-performance computing (HPC) for electricity and data center capacity, raising the prospect of changing mining economics.
Hashrate Downtrend Signals Changing Economics
Zagury said the ongoing decline in hashrate marks a notable turn for Bitcoin’s mining landscape. Hashrate, a measure of the total computational power securing the network, typically grows over time as miners add machines. A sustained pullback suggests some operators are unplugging equipment or slowing expansion, often due to tighter margins following Bitcoin’s most recent halving, volatile energy costs, and constrained access to capital.
AI and HPC Intensify Competition for Power
Rising demand from AI and HPC workloads is tightening power markets and straining transmission and substation capacity globally. Mining firms are increasingly competing for:
- Long-term electricity contracts and firm power supply
- Data center sites, transformers, and cooling infrastructure
- Skilled labor and financing for large-scale deployments
This competition can raise costs for miners or delay buildouts, prompting some operators to evaluate reallocating resources toward higher-value compute or to pursue partnerships that diversify revenue.
Implications for Miners and the Network
If the trend persists, Bitcoin’s difficulty—adjusted roughly every two weeks to target 10-minute block times—may ease, partially offsetting revenue pressure for remaining miners. Even so, miner profitability will continue to hinge on BTC price, transaction fee levels, energy costs, and access to efficient hardware and low-cost power. The downtrend may also accelerate geographic shifts toward regions with surplus energy and supportive policy frameworks.
Background: What Hashrate Measures
Hashrate reflects the aggregate computational effort miners contribute to validate transactions and secure Bitcoin’s blockchain. Higher hashrate generally strengthens network security by making attacks more expensive. Conversely, a sustained decline can indicate rising operating pressures on miners, though the protocol’s difficulty adjustment is designed to stabilize block production over time.
