Introduction: What Does "Mining" Really Mean?
When you hear the term "mining", what comes to mind? For those familiar with Web3 or the broader cryptocurrency space, it's likely a well-known concept. During the peak of the crypto boom, mainstream media coverage helped even casual observers understand that mining involves using computing power to validate transactions and earn rewards.
At its height, Bitcoin mining evolved into a full-scale industry. Massive data centers—commonly known as mining farms—sprang up worldwide, powered by electricity and high-performance GPUs. Where there was power and hardware, miners followed.
But beyond traditional proof-of-work mining, there’s a lesser-known variant gaining attention: lottery mining.

What Is Lottery Mining?
Unlike conventional mining that relies on massive computational power, lottery mining operates on a radically different principle: randomness over brute force.
Devices used in this method—often called lottery miners—are typically low-power, microcontroller-based systems like those built around the ESP32 chip. Instead of continuously hashing at high speeds, they submit random guesses every 10 minutes—the approximate block time for Bitcoin—and hope to get lucky.
Yes, it's essentially like buying a Bitcoin lottery ticket every 10 minutes. If your device happens to guess a valid hash that meets the network’s difficulty target, you win the entire block reward—currently 6.25 BTC, all yours.
Technically speaking, this isn't new. It mirrors solo mining, the original way early Bitcoin miners operated before pooled mining became dominant. The key difference? No sharing. No splitting rewards. If you win, it's 100% yours.
So, driven by curiosity—and maybe a touch of naive optimism—I decided to build one myself.
Building My Own Mining Dream
Rather than buying a pre-assembled unit, I opted for the DIY route. After some research, I discovered most compact lottery miners are based on development boards like the LILYGO T-Display, which features an ESP32 microcontroller with a built-in screen.
I ordered the bare components online and began assembling my own rig from scratch.
While the “mining” part doesn’t require complex assembly—the core is just a single board flashing custom firmware—I added a basic plastic case to protect the circuitry. This setup is common among hobbyists and looks surprisingly polished once complete.
You’ll find many ready-to-use versions of this exact design sold under keywords like “lottery miner” on e-commerce platforms. But building it myself gave me deeper insight into how these devices actually work.
Thus began my journey into low-stakes, high-dreams mining.
Flashing the Firmware: The Ritual of Activation
With hardware assembled, it was time for software installation. Most such devices run Nerd Miner, an open-source firmware specifically designed for ESP32-based lottery mining.
The project—hosted on GitHub as NerdMiner_v2—provides detailed documentation for installation and configuration.
For experienced users, flashing the firmware via command line tools is straightforward. But for beginners, the developers offer a web-based flashing tool, making setup accessible even without technical expertise.
Here’s how it works:
- Connect your ESP32 board via USB.
- Open the web flasher (preferably in Chrome).
- Select your board model from the dropdown.
- Click “Flash” and allow the browser to connect to the device.
- Wait for the progress bar to complete.
Once done, the board reboots and displays a QR code on its screen—your gateway to configuration.

Configuring and Launching the Miner
Configuration is simple: scan the QR code with your smartphone. Your phone will connect to the miner’s local Wi-Fi network and automatically open a web interface.
From there, you’ll configure several key settings:
- Wi-Fi Name & Password: To maintain internet connectivity.
- Pool URL & Port: The Bitcoin node your miner connects to. Nerd Miner includes default options.
- BTC Address: Your personal Bitcoin wallet address—this is where any potential reward goes.
- Time Zone: Set in UTC format (e.g., UTC+8 for Taiwan).
After entering these details, click “Save” and reboot. The device will reconnect and begin mining.
Once configured, it retains settings across reboots. To change them later, simply hold down the bottom-right button to bring back the QR code and re-enter setup mode.
The interface also shows real-time stats: uptime, total hashes computed, current hash rate (measured in KH/s), and valid blocks found.
Reality Check: Dreams vs. Probability
After setting everything up, I let the miner run continuously for over 32 hours.
Results?
- Total hashes computed: 6.5 billion
- Average hash rate: 56.3 KH/s
- Valid blocks found: 0
Not surprising—but still a little disappointing.
During testing, I also noticed occasional drops in performance: hash counts resetting, time restarting. These hiccups likely stem from Wi-Fi disconnections or brief firmware crashes.
Even with stable power and network conditions, uninterrupted operation isn’t guaranteed. This isn’t industrial-grade hardware; it’s a hobbyist project running on consumer-grade components.
Let’s put the odds in perspective:
- The global Bitcoin network hashes at over 600 exahashes per second (EH/s).
- My device contributes roughly 0.000056 EH/s.
- That’s about 1 in 10 million of the total network hashrate.
Winning with solo mining at this scale is less about strategy and more about divine intervention.
Unless you’ve accumulated centuries of good karma, hitting a 6.25 BTC jackpot is astronomically unlikely.
Final Thoughts: Mining as a Hobby, Not an Income
So, should you try building your own lottery miner?
Absolutely—if your goal is learning, tinkering, or embracing the spirit of decentralization.
But if you're hoping to make money? Save your time and electricity.
This isn’t a get-rich-quick scheme. It’s more akin to owning a digital lucky charm—a functional art piece that silently participates in the Bitcoin network every 10 minutes, praying for a miracle.
Think of it as:
- A fun STEM project for learning about cryptography and networking.
- A quirky desktop gadget with purpose.
- A symbolic act of faith in decentralized systems.
It won’t replace your job. But it might deepen your appreciation for how Bitcoin actually works under the hood.
Frequently Asked Questions
Q: Can I really win 6.25 BTC with a small lottery miner?
A: Technically yes—if you’re the first to find a valid block hash. But the odds are extremely low due to minimal hash power compared to industrial miners.
Q: Do I need technical skills to set up a lottery miner?
A: Basic computer skills are enough. The Nerd Miner web flasher simplifies installation, and setup uses a phone-friendly web interface.
Q: Is lottery mining profitable?
A: Almost never. With electricity costs and low chances of winning, profitability is negligible. It's best treated as an educational hobby.
Q: What hardware do I need?
A: An ESP32-based board like LILYGO T-Display (~$20–$30). Everything else—firmware and tools—is free and open-source.
Q: Can I use any Bitcoin wallet address?
A: Yes. Just ensure it’s a valid receiving address from a secure wallet you control.
Q: How often does a winner get picked?
A: On average, every 10 minutes globally—one block per interval. But individual devices only get one guess per cycle.
