With Bitcoin's network hashrate recently surpassing 100 exahashes per second (EH/s) and the dry season—a period of higher electricity costs in many major mining regions—approaching, the mining industry stands at a critical juncture. This phase often separates efficient, high-performance miners from older, less efficient models. As Bitcoin enters an era dominated by powerful mining rigs, a pressing question emerges: is mining still a profitable venture?
To answer this, industry experts recently gathered for a detailed直播 (livestream) analysis of the latest mining hardware, focusing on the capabilities and economic potential of next-generation machines.
Introducing the Avalon A11 Series Miners
The Avalon A11 series, developed by Canaan Creative, represents the latest generation of Bitcoin application-specific integrated circuit (ASIC) miners that are now in mass production. This series succeeds the A10 line, which included models like the Avalon 1047 (31 TH/s at 58 J/TH) and the Avalon 1066 (50 TH/s at approximately 63 J/TH). Market demand for these efficient machines is so high that orders are backlogged well into the next season.
The A11 series features two primary models:
- Avalon A1166: Boasts a nominal hashrate of 68 TH/s with an energy efficiency of 46 J/TH.
- Avalon A1146: Offers a nominal hashrate of 56 TH/s with an energy efficiency of 57 J/TH.
This new generation marks a significant leap, delivering a roughly 36% increase in hashrate over its predecessors and solidifying the trend that hashrates above 60 TH/s are the new standard for competitive mining.
Live Testing and Performance Metrics
To validate these impressive specs, the new units were put to the test in a live, off-site demonstration. After over an hour of continuous operation, the results were compelling:
- The A1166 consistently achieved a hashrate of 68.8 TH/s with a power consumption of 46.3 J/TH. Its operational noise was measured at approximately 75 decibels.
- The A1146 delivered a solid 60.22 TH/s.
Representatives from Canaan further noted that, under optimal conditions, these machines can peak at even higher capacities—reaching up to 73.4 TH/s for the A1166 and 61.45 TH/s for the A1146.
Key Features and User-Centric Design
Beyond raw power, the A11 series incorporates several design innovations aimed at improving usability, security, and operational flexibility.
- All-in-One Unit: The矿机 (miner) comes as a complete package, eliminating the need for users to separately purchase a power supply unit (PSU). This plug-and-play design simplifies setup, making it more accessible for newcomers.
- Daisy-Chain Networking: Support for Ethernet daisy-chaining allows multiple miners to connect in a series, significantly reducing cabling complexity and server port requirements in large-scale mining farms. This feature simplifies backend batch configuration.
- Adaptable 3300W Power Supply: The integrated robust PSU protects the hardware from power outages and voltage instability. Crucially, it allows for underclocking the machine during periods of low Bitcoin prices to reduce energy consumption and preserve profitability. A four-fan configuration ensures effective heat dissipation under various operating conditions.
- Enhanced Security: The main control board is equipped with multi-layer encryption algorithms to prevent hashrate theft. It also features a Canaan K210 AI chip, which adds a layer of virus resistance, protecting the miner's operational integrity.
Profitability Analysis: Is It a Money Printer?
The ultimate test of any miner is its return on investment. Based on its nominal hashrate and assuming an electricity cost of $0.036 per kWh, the A1166 is projected to generate:
- Daily Bitcoin Mined: Approximately 0.001314 BTC
- Daily Revenue: ~$77 (based on a static Bitcoin price)
- Daily Electricity Cost: ~$27
- Estimated Daily Net Profit: ~$50
With an official price point of $16,252, the **static payback period for the A1166 is roughly 8.5 months** at current Bitcoin valuations. The more affordable A1146, priced at $9,999, has a projected static payback period of about 7 months.
It's important to emphasize that these are simplified calculations. Actual returns are dynamic and heavily influenced by fluctuating factors like Bitcoin's price, network difficulty, and pool luck.

Availability and Market Outlook
A common critique in the mining industry is the delay between product announcement and actual delivery. Canaan representatives confirmed that the A11 series is not a "PPT miner" but was already in mass production as early as September, with initial batches allocated for longtime clients. Widescale delivery for all customers is slated for January and February.
The production timeline is closely tied to the supply of chips; typically, final miner assembly can be completed within two weeks of chip delivery. This suggests January will be a pivotal month for the widespread deployment of these powerful new machines across global mining operations.
Frequently Asked Questions
Q: Are small-scale miners being forced out of the market?
A: While institutional players purchasing tens of thousands of units at a time are rising, a niche for smaller miners remains. They often excel at finding unique, low-cost power sources and flexible hosting arrangements. Their smaller scale can also make them more agile in relocating equipment or trading second-hand machines.
Q: Will Bitcoin's network hashrate experience a massive surge?
A: Hashrate and profitability are intrinsically linked. A surge in hashrate is often correlated with a rising Bitcoin price. If the price remains stable, the onset of the dry season with its higher electricity costs could actually force older, inefficient miners offline, potentially offsetting the hashrate growth from new models like the A11 series. Long-term, hashrate will grow as more efficient machines deploy, but this is typically balanced with market dynamics.
Q: What is a "static payback period"?
A: It's a simplified calculation that estimates the time required for a miner to generate enough net profit to cover its initial purchase cost, assuming all variables (Bitcoin price, network difficulty, electricity cost) remain constant. In reality, these factors change constantly, so it serves as a baseline rather than a guarantee.
Q: Why is energy efficiency (J/TH) so important?
A: Energy efficiency measures how much electricity is consumed to perform one terahash of calculations. A lower J/TH value means the miner does more work for less power, which is the primary determinant of profitability, especially when Bitcoin's price is low or electricity costs are high.
Q: Is now a good time to get into Bitcoin mining?
A: Mining is a high-risk, capital-intensive business. While efficient hardware is crucial, success depends on securing ultra-cheap electricity, managing operational logistics, and navigating the volatility of the crypto market. It requires significant research and risk tolerance.
Q: How does daisy-chaining save costs?
A: It drastically reduces the amount of Ethernet cabling and network switches needed in a large mining farm. Instead of running a cable from a switch to every single miner, cables can connect miners to each other in a chain, saving on infrastructure, time, and maintenance.
