Introduction
CPU mining remains one of the most accessible ways to earn cryptocurrency today. Even in an era where ASICs dominate the hash wars, using your computer’s processor still holds unique value. For beginners, hobbyists, or those seeking low-cost entry into the crypto space, CPU mining offers an approachable and educational path. In this guide, you’ll discover how it works, which coins are best for CPUs, and whether this old-school method still makes sense in today’s market.
What is CPU mining?
CPU mining uses your computer’s central processing unit to perform the calculations needed to validate blockchain transactions. While GPUs and ASICs have largely taken over, CPUs still serve a purpose in mining algorithms specifically designed to resist hardware monopolies. Algorithms like RandomX (Monero), Ghostrider (Raptoreum), and Yespower (Verus Coin) favor decentralization and maintain CPU accessibility.

Best cryptocurrencies for CPU mining
- Monero (XMR): A privacy coin running on RandomX, ideal for CPU use.
- Raptoreum (RTM): Powered by Ghostrider, offering low difficulty and good rewards for multi-core systems.
- Dero (DERO): Built on AstroBWT, designed for CPU optimization.
- Verus Coin (VRSC): Uses VerusHash and maintains ASIC resistance.
These coins are chosen not only for profitability but for their community support and long-term commitment to decentralization.
CPU mining vs GPU and ASIC mining
Here’s how CPU mining compares to its hardware-heavy counterparts:
| Feature | CPU | GPU | ASIC |
|---|---|---|---|
| Cost | Low | Medium | High |
| Setup Difficulty | Easy | Medium | Hard |
| Power Efficiency | Low | High | Very High |
| Algorithm Flexibility | Medium | High | Very Low |
| Resale Value | Low | Medium | Low |
| Beginner Friendly | Yes | Sometimes | No |
As you can see, CPU mining shines in accessibility and versatility, but lags in raw efficiency. It’s less about profit, more about participation.
Is CPU mining still profitable?
Profitability is all about context. Mining Monero with a Ryzen 9 CPU might earn you $0.30–$0.50/day at low electricity rates, but that number fluctuates with network difficulty and coin prices.
- Low electricity = higher ROI.
- Modern CPUs = better hashrate.
- Right coin = better long-term value.
Don’t expect riches. Do expect a hands-on lesson in how blockchain consensus actually works. That alone can be worth your effort.
Step-by-step guide to start CPU mining
- 1. Get a wallet: Start with a secure option like Feather Wallet for Monero.
- 2. Choose your coin: Pick a CPU-friendly option like XMR or RTM.
- 3. Download mining software: We recommend XMRig, SRBMiner, or cpuminer-opt.
- 4. Join a pool: Solo mining is not recommended — use pools like SupportXMR.
- 5. Configure the miner: Input your wallet address and pool settings.
- 6. Monitor health: Keep temperatures below 80°C using HWMonitor or Core Temp.
When CPU mining actually makes sense
It might not make headlines, but CPU mining does have its place:
- You already own a high-end processor.
- You have idle machines at home or work.
- Your electricity is cheap or free.
- You believe in decentralization and supporting smaller coins.
It’s the long game, not a sprint.
Legal and security considerations
- Only mine on your own devices — cryptojacking is illegal and unethical.
- Use antivirus-safe mining software from verified sources.
- Understand local tax rules — mined coins are usually considered taxable income.

FAQs
Can I mine Bitcoin with a CPU?
Technically yes, but you won’t earn anything. Bitcoin mining is far too competitive for CPUs to be relevant.
Is CPU mining legal?
Yes, but always check your country’s regulations and declare earnings if required.
What’s the best CPU for mining?
AMD Ryzen 9 5950X and Intel Core i9-13900K are currently top-tier for CPU mining efficiency.
Is CPU mining safe for my hardware?
Yes, if properly monitored. Keep temperatures in check and avoid 24/7 full-load operation without breaks.
Final thoughts
CPU mining is like the analog watch of the crypto world — it may not be the flashiest, but it’s reliable, accessible, and still ticking. For those with the curiosity to explore and the discipline to optimize, it offers an entry into mining that teaches more than it earns. Whether you’re testing the waters or running rigs on the side, CPU mining lets you learn the ropes without diving into the deep end. And sometimes, that’s the smartest way to start.
