Thinking about trying crypto mining, but don’t want to spend a fortune? We’ve picked three beginner-friendly mining machines on Amazon, all priced under $500. These devices were chosen for their ease of use, solid reviews, reliable sellers, and good balance of price and performance. They’re perfect for anyone curious about mining Bitcoin or other SHA-256 coins, offering a low-risk way to learn the ropes and see how mining works at home.
Note: These miners are designed for learning and hobby use. Don’t expect big profits, as electricity costs often outweigh earnings.
1. Canaan Avalon Nano 3S BTC Miner
The Avalon Nano 3S is a plug-and-play SHA-256 ASIC miner made for people who want to try crypto mining at home without crazy power bills. It delivers about 6 TH/s of Bitcoin-class hashing power while drawing ~140 watts. It isn’t going to make you rich overnight, but it’s solid for learning, testing a rig, or earning small rewards.
It’s built by Canaan, a trusted name. Quiet, compact, and efficient enough for home setups, if your electricity cost isn’t too high.
Coins it can mine
- Bitcoin (BTC)
- Bitcoin Cash (BCH)
- Fractal Bitcoin (FB)
- eCash (XEC)
- DigiByte (DGB)
- Any coin using the SHA-256 algorithm (or via mining pools / NiceHash SHA-256)
| Pros | Cons |
|---|---|
| High brand reliability (Canaan) | Only supports SHA-256 coins, not useful for many altcoins |
| Relatively efficient: 6 TH/s for ~140 W | Power cost may eat into earnings heavily |
| Quiet enough for home usage (33-40 dB) | Payback time can be very long with the current BTC difficulty & electricity rates |
| Small, compact size; easy to set up | Not profitable for many unless electricity is cheap |
Earning Potential (Estimate)
Assumptions:
- Mining Bitcoin/SHA-256 pool
- Full-time operation
| Scenario | Electricity Cost | Daily Net | Monthly Net | Yearly Net |
|---|---|---|---|---|
| Standard US rate | $0.10/kWh | ≈ $0.00 (break-even) | ≈ −$0.07 | ≈ −$0.84 |
| Higher US rate | $0.20/kWh | −$0.34/day | ≈ −$10.20 | ≈ −$124 |
| Cheap electricity | $0.05/kWh | +$0.17/day | ≈ +$5.10 | ≈ +$62 |
| Solar power (no grid cost) | Free | +$0.34/day | ≈ +$10.20 | ≈ +$124 |
On regular US power, the Avalon Nano 3S is basically break-even. If your local rates are high, you’ll lose money. But with cheap or free energy (like solar), it can actually generate a modest profit, making it a fun way to mine Bitcoin at home without worrying about electricity bills.
2. Bitaxe Gamma 601 ASIC Bitcoin Miner
The Bitaxe Gamma 601 is a compact, energy-efficient ASIC miner built for the SHA-256 algorithm. It delivers about 1.2 TH/s hash power while consuming only ≈17-20 W of electricity. Lightweight and mostly silent, it’s designed for home or hobby-use miners who want low power draw and hassle-free setup.
It comes with built-in WiFi, open firmware options, and includes a power supply & stand in many variants. Great if you want something small that doesn’t overload your electric bill.
Coins it can mine
- Bitcoin (BTC)
- Bitcoin Cash (BCH)
- Bitcoin SV (BSV)
- Other coins using SHA-256 (e.g. via SHA-256-based pools or NiceHash)
| Pros | Cons |
|---|---|
| Extremely low power draw (≈17-20 W), very efficient for its hash rate. | Very low total hash compared to big ASICs; limited potential in high-difficulty network conditions. |
| Quiet and compact design, good for a desk or a small space. | WiFi + easy firmware/monitoring; “open-source” ethos in some versions. |
| Includes useful extras like PSU & stand (in most bundles). | Payback is slow; profitability is sensitive to electricity cost and BTC price. |
| WiFi + easy firmware / monitoring; “open-source” ethos in some versions. | Efficiency gains are limited; overclocking increases power and heat (reducing efficiency & raising risk). |
Earning Potential (Estimate)
Assumptions:
- SHA-256 mining (BTC/pool)
- Runs 24/7
| Scenario | Electricity Cost | Daily Net | Monthly Net | Yearly Net |
|---|---|---|---|---|
| Standard US rate | $0.10/kWh | ≈ +$0.03/day | ≈ +$0.78 | ≈ +$8.8 |
| Higher US rate | $0.20/kWh | ≈ −$0.04/day | ≈ −$1.20 | ≈ −$14.9 |
| Cheap power ($0.05/kWh) | $0.05/kWh | ≈ +$0.05/day | ≈ +$1.50 | ≈ +$18.3 |
| Solar (free power) | Free | ≈ +$0.07/day | ≈ +$2.02 | ≈ +$23.7 |
Takeaway: The Bitaxe Gamma 601 is ideal for hobbyists who want a quiet, low-power miner that can produce a small positive return with cheap or free electricity. It’s not a path to serious income, but it’s great for learning, experimenting, or continuously mining small amounts of SHA-256 coins.
3. Sources BitAxe Gamma BM1370
The Sources BitAxe Gamma BM1370 is a compact SHA-256 ASIC miner aimed at hobbyists and experimenters. It offers about 1.2 TH/s of hash power, drawing around 17-20 W of electricity. It uses the BM1370 chip (same generation used in the Antminer S21 Pro) and is marketed to include PSU, stand, WiFi connectivity, and an OLED or basic display in many variants.
It’s ideal if you want a miner that runs quietly, is cheap to run, and gives you entry into Bitcoin/SHA-256 mining without needing a warehouse or massive cooling setup.
Coins it can mine
- Bitcoin (BTC)
- Bitcoin Cash (BCH)
- Bitcoin SV (BSV)
- eCash (XEC)
- Any coin using SHA-256 via mining pools or NiceHash
| Pros | Cons |
|---|---|
| Excellent efficiency (≈ 14-15 J/TH), good balance of power use vs output | Very limited hash power vs high-end industrial ASICs; earnings will be small |
| Includes extras in many bundles (PSU, stand, display), makes setup easier | Still only SHA-256 coins; no flexibility for altcoin mining outside that algorithm |
| Quieter, smaller footprint, better for home/desk setups | Margins are razor-thin; difficulty rises could make profitability worse |
| Includes extras in many bundles (PSU, stand, display), making setup easier | Reliability/support depend heavily on the seller; firmware/heat issues are possible |

Frequently Asked Questions
Yes. You can run multiple units at once to boost total hashrate. For example, two Avalon Nano 3S miners will double output. Just remember, each device adds to electricity costs, so profitability still depends on cheap or solar power.
No. Most come with built-in WiFi and their own interfaces. You only need a basic device (like a laptop or even a phone) to set up, monitor, or connect them to a mining pool.
With proper ventilation and stable power, small ASIC miners often last 2–4 years. Dust buildup, overheating, or constant overclocking can shorten lifespan, so simple care like keeping them cool and clean extends their usefulness.
