Best Kaspa Miners July 2025? Is KAS Mining Still Profitable?
Kaspa (KAS) has become popular among proof-of-work coins due to its speed, scalability, and active developer community, and as opposed to many altcoins that quickly fade, Kaspa has been consistent with updates and unique features like BlockDAG architecture.
Its one-second block time, open-source nature, and fair launch have drawn in miners who are tired of centralized projects without pre-mining or VC backing. However, due to the competition level in mining continuing to rise, people have been asking, “Is Kaspa mining still profitable today?”
Why is Kaspa (KAS) Different?
Kaspa is considered different because it runs on the kHeavyHash algorithm, which is made to be lightweight and GPU-friendly, plus its BlockDAG structure allows multiple blocks to be created and confirmed at the same time, leading to faster and better transactions than traditional blockchains.
Initially, its mining was attractive to GPU miners using common hardware like Nvidia’s RTX 3070 and 3080 to perform well, also helping in consuming less power. However, the introduction of ASIC miners in late 2023 and 2024 changed the game.
Best Kaspa Miners in 2025
1. Bitmain Antminer KS5 Pro
Bitmain Antminer KS5 Pro (21Th)
Brand: BitmainRelease Date: Mar 2024
Algorithm: kHeavyHash
Electricity Cost: 0.02 USD / KWh
| Best Coin | Hashrate | Power | Algorithm | Mining Reward | Power Cost | Profit (USD) |
|---|---|---|---|---|---|---|
 Kaspa (KAS) |
21 TH/s | 3150 W | kHeavyHash | USD | USD | 9.78 USD |
The Bitmain Antminer KS5 Pro is a powerful Kaspa ASIC miner offering a high hashrate of 21 Th/s while consuming 3150 W of power. It has 4 in-built air-cooling fans and a dimension of 430 x 195 x 290 mm and weighs 15800g.
2. IceRiver KS3M
Release Date: Oct 2023
Algorithm: kHeavyHash
Electricity Cost: 0.02 USD / KWh
| Best Coin | Hashrate | Power | Algorithm | Mining Reward | Power Cost | Profit (USD) |
|---|---|---|---|---|---|---|
| Kaspa (KAS) |
6.00 TH/s | 3400 W | kHeavyHash | USD | USD | 1.59 USD |
Currently, this miner can be seen as the heavyweight champion of the Kaspa in terms of mining, having an impressive 6 TH/s hashrate and a power draw of 3400W. It has the best balance of power and efficiency on the market.
The upfront cost ranges from $6000 to $9000, but miners with access to cheap electricity can reach ROI in under a year.
3. IceRiver KS2
Release Date: Sep 2023
Algorithm: kHeavyHash
Electricity Cost: 0.02 USD / KWh
| Best Coin | Hashrate | Power | Algorithm | Mining Reward | Power Cost | Profit (USD) |
|---|---|---|---|---|---|---|
| Kaspa (KAS) |
2.00 TH/s | 1200 W | kHeavyHash | USD | USD | 0.50 USD |
IceRiver KS2 is the more accessible option in the lineup, offering 2 TH/s at around 1200W and does not compete with the KS3M in power, though it is still a decent choice for smaller-scale miners who want to get started without spending much.
4. Nvidia RTX 3070
These can deliver over 1 GH/s per card with optimized settings and efficient power usage, but ASICs have now made GPU mining largely unprofitable unless electricity is free or nearly free.
Is Kaspa Mining Still Profitable?
Before answering this question, some factors could make Kaspa mining profitable or less profitable; hence, let’s discuss them before answering.
1. Electricity cost
Miners who have access to rates below $0.06 per kWh can turn a profit with high-efficiency ASICs, and those paying anything above $0.10 per kWh are likely to see little or no returns.
2. Network difficulty and hashrate
ASIC, having been adopted, has made network difficulty and hashrate higher. See the system as one that rises as more powerful miners enter the network, cutting into potential earnings for every participant.
3. Kaspa’s price
This is also a key factor when considering whether Kaspa is profitable. Dating back to early 2025, the coin experienced significant price surges, allowing minors access to a healthy margin. However, due to its volatility, miners banking on long-term gains might choose to hold onto their coins rather than selling immediately.
4. Hardware costs and ROI
The costs of ROI and hardware costs vary depending on the model and their market conditions. Let’s say, for a KS3M unit, it could pay for itself in an ideal environment in 6 to 12 months.
So, having considered all these factors, you have probably been able to derive an answer to the question: Is mining Kaspa profitable?
Factors to Consider Before Mining
The Kaspa ASIC miners’ community is an active one and requires significant cooling and airflow, and as such, running them at home is not recommended unless you have proper ventilation and do not mind the noise.
If you are considering mining alone, you should know that the method is no longer practical for Kaspa due to the high difficulty; hence, the best option is to join a mining pool such as WoolyPooly, KaspaPool, or OKKPool.
Before buying any machine, check that the manufacturer provides solid support and regular updates to keep the device running at peak performance, as monitoring tools, firmware updates, and tuning options also affect performance and efficiency.
Conclusion
Kaspa mining in 2025 has developed into something serious, which is dominated by high-end ASIC miners, raising a high possibility of making a profit, but only for those who are ready to implement the right strategy, equipment, and electricity costs.
High-efficiency ASICs like the IceRiver KS3M can help a lot, also make sure your power costs are low enough to support the investment, and make you earn more.
