Bitcoin mining has returned to a period of broad profitability for operators with access to competitive electricity rates. As of 23 April 2026, the network’s hashprice stood at $36.46 per petahash per second — a level at which every one of the 14 top-ranked ASIC mining rigs tracked in current profitability data is generating positive daily returns for operators paying $0.04 per kilowatt-hour for power.
The Hardware Landscape
Bitmain’s Antminer S23 Hydro 3U leads the field in estimated daily earnings, generating $31.62 per unit per day at the benchmark electricity cost. The figure underlines both the continued dominance of Bitmain’s hardware within the professional mining industry and the extent to which efficiency gains in ASIC design have transformed the economics of the sector over the past two years, according to data from Bitcoin.com News.
Of the 14 top-ranked machines, 13 require either hydro-cooling or immersion-cooling systems to operate at peak efficiency — a hardware reality that has significant implications for mining economics. The capex and opex associated with advanced cooling infrastructure has effectively raised the barrier to entry for new mining operations, concentrating hash rate among well-capitalised players with purpose-built facilities.
The Electricity Cost Sensitivity
The $0.04/kWh benchmark used in profitability analysis represents the approximate cost available to the most competitive large-scale miners — typically those with direct access to renewable energy sources, hydroelectric facilities, or long-term power purchase agreements with utilities. Retail electricity prices of $0.10–$0.15/kWh — common in most residential settings — would render the majority of the hardware unprofitable or marginally so, illustrating why home mining has become essentially unviable and why professional mining has industrialised so dramatically.
Hashrate and Network Security
The profitability environment feeds directly into Bitcoin network security. When mining is broadly profitable at competitive electricity rates, new machines continue to be deployed and existing machines run at full capacity, pushing total network hashrate higher. Higher hashrate means the network is more computationally secure against 51% attacks. April 2026’s healthy profitability metrics suggest that network security will remain robust through the near term, providing a stable foundation for the broader Bitcoin ecosystem.
