Bitmain Antminer L3++ Mining Profit Calculator

·

The Bitmain Antminer L3++ is a specialized ASIC miner designed for cryptocurrencies that use the Scrypt hashing algorithm. Released in May 2018, this mining rig was once a top-tier option for mining popular coins like Litecoin and Dogecoin. While newer models have since surpassed it in efficiency, the Antminer L3++ remains relevant for small-scale miners or those operating in low-cost electricity environments.

With a hash rate of 596.00 Mh/s and a power consumption of 1050W, understanding its current profitability requires up-to-date calculations based on network difficulty, coin value, and electricity costs. This guide breaks down everything you need to know about maximizing returns—or recognizing when it might be time to upgrade.

Understanding the Antminer L3++ Specifications

Before diving into profitability, let’s review the core technical specs:

These numbers were impressive at launch, especially compared to earlier L3 models. However, with the rise of more efficient miners like the Antminer L7, the L3++ now faces stiff competition in terms of energy efficiency and output.

Current Profitability Analysis (2025)

Mining profitability fluctuates daily due to changes in cryptocurrency prices, network difficulty, and electricity costs. Below is an overview of estimated earnings and profits for the Antminer L3++ across major Scrypt-based coins, assuming an electricity cost of $0.10 per kWh—a common benchmark for residential mining setups.

Estimated Daily Revenue by Coin

Even under optimal conditions, the Antminer L3++ operates at a net loss when electricity costs exceed $0.10/kWh. Only miners with access to extremely cheap or free power (e.g., solar surplus, industrial discounts) might break even temporarily during market spikes.

Factors Affecting Mining Profitability

Several dynamic variables influence whether mining with the L3++ makes financial sense today:

1. Electricity Cost

This is the single biggest factor. At $0.15/kWh or higher, losses increase significantly. For example:

2. Network Difficulty

As more powerful miners join Scrypt-based networks (especially Litecoin), difficulty rises—reducing individual rewards over time.

3. Cryptocurrency Market Price

Short-term rallies in DOGE or LTC can briefly boost revenue, but these are unpredictable and often short-lived.

4. Hardware Lifespan & Maintenance

Older units may suffer from reduced performance, fan failures, or increased downtime—further cutting into already slim margins.

Is the Antminer L3++ Still Worth Using?

For most users in 2025, the answer is no—unless you meet specific criteria:

✅ You have access to sub-$0.05/kWh electricity
✅ You're using the miner as a learning tool or hobby project
✅ You're mining during temporary network dips or coin pumps

Otherwise, continuing to run the L3++ will likely cost more than it earns.

That said, repurposing the device—such as using it for heat generation in cold climates—can offer indirect value.

Frequently Asked Questions (FAQ)

Q: Can I still mine Dogecoin profitably with the Antminer L3++?

A: Not under standard conditions. While Dogecoin has high visibility and community support, network difficulty and electricity costs make mining unprofitable for older hardware like the L3++. Even with low power rates, returns are minimal.

Q: What is the break-even electricity cost for the Antminer L3++?

A: Based on current Litecoin and Dogecoin values, you’d need electricity priced below $0.04/kWh to break even—rare for most residential users.

Q: Should I upgrade from the L3++ to a newer model?

A: Yes, if profitability is your goal. Modern Scrypt miners like the Antminer L7 offer significantly better efficiency (e.g., ~0.31 J/MH vs. 1.76 J/MH), translating to much higher returns per watt.

Q: Can I use NiceHash with the Antminer L3++?

A: Technically yes, but revenue remains low due to declining demand for Scrypt hashing power on NiceHash platforms. Expect minimal returns and potential idle periods.

Q: How long does an Antminer L3++ typically last?

A: With proper cooling and maintenance, these units can last 4–6 years. However, performance degradation over time reduces mining output gradually.

Final Thoughts

While the Bitmain Antminer L3++ played a pivotal role in the early days of Scrypt mining, its relevance has faded in today’s competitive landscape. With negative daily profits under average energy costs and outdated efficiency metrics, it serves best as a historical piece or educational device rather than a serious income generator.

For those still holding onto their L3++ units, consider evaluating upgrades or alternative uses. The future of mining lies in efficiency, scalability, and smart resource management—not legacy hardware struggling to cover operational costs.
