Best Bitcoin SOLO Miner In 2025

As the price of Bitcoin breaks through the $100,000 mark, the SOLO mining mode has received more attention. Many cryptocurrency enthusiasts favor Small ASIC SOLO miners due to their low power consumption, low noise, and flexible deployment. Such devices are suitable for home mining and provide stable profit opportunities under low power consumption conditions. This article will conduct an in-depth comparative analysis of the most suitable SOLO miners for individual purchase.

I. Why Choose SOLO Miner? The unique advantages of small solo miners

Unlike joining a mining pool, SOLO mining means that miners can enjoy the entire block reward alone without sharing the profit with others. In March 2025, a user successfully mined a block using a small Bitaxe solo miner and obtained Bitcoin worth approximately $260,000, achieving an astonishing return on investment of 21,816%.

II. We have selected 10 popular Bitcoin SOLO miners from the Bitaxe, Lucky, and NerdMiner series currently on the market. They all use the SHA-256 algorithm to mine Bitcoin. The following content compares hash rate, power consumption, energy efficiency ratio, noise, etc.

III. Analyze the miners with the most crucial advantages according to the above table:

1. Highest-performance high hash rate SOLO miner: Bitaxe SupraHex 701 4.2Th/s

• Among solo miners with a hash rate of 4Th/s and above, it delivers an ultra-high hash rate of 4.2Th/s with low power consumption of only 90W. Its energy efficiency ratio is 0.012J/Gh lower than the LV08, giving it a distinct advantage.

• Equipped with dual 80mm ball-bearing fans to minimize operating temperatures.

2. The SOLO miner with the best hash rate: Lucky miner LV08 4.5Th/s

• Among all the above models, the highest hash rate is 4.5Th/s, 3Th/s higher than SupraHex 701.

• The energy efficiency is very average, but the noise is quieter than the high hash rate SupraHex 701, 8dB lower.

3. The most power-saving SOLO miner: Bitaxe Gamma 601 1.2Th/s

• The lower the energy efficiency ratio, the better. Among the 10 SOLO miners, the best energy efficiency ratio is only 0.014/J/Gh.

• Compared with the LV07, which has a power consumption of 25W for a hash rate of 1T, the Bitaxe Gamma 601 has an advantage with a low power consumption of 17W and a high hash rate of 1.2 T.

• With a power consumption of only 0.017 kWh per hour, it consumes approximately 0.41 kWh daily, showing obvious advantages in long-term use. If the local electricity price is $1 per kWh, 0.41 X $1 = $0.41, and $0.41 X 30 = $12.3 per month.

4. The most silent SOLO miner: Lucky Miner LV06 0.5Th/s

• It has the lowest noise value among all the miners in the above table. The volume of <35dB is even lower than the sound of turning pages in a library. If it is 15-30dB, it is equivalent to the sound of breathing and is almost inaudible.

• It has the same hash rate, power consumption, and energy efficiency ratio values as the NerdAxe Bitcoin Solo Lottery Miner. Still, the LV06 maintains perfect silence in terms of noise.

Conclusion:

For those seeking high hash rates without succumbing to high power consumption, the top-performing Bitaxe SupraHex 701 is the perfect choice. The Lucky Miner LV08 is suitable for adventurers who want to obtain a high hash rate. It uses top-notch computing power to increase the block-breaking probability, with higher returns but slightly higher energy consumption. The Bitaxe Gamma 601 has an extreme energy efficiency ratio of 0.014j/Gh, making it a power-saving artifact for users in areas with high electricity costs, suitable for cost-conscious energy-saving enthusiasts. The Lucky Miner LV06 operates with a sound lighter than turning pages, perfectly integrating into the bedroom/study environment, suitable for those who focus on silence.
