In a stunning stroke of luck, an independent Bitcoin miner recently struck digital gold by successfully mining a full Bitcoin block using a low-cost, pocket-sized mining device. The miner, identified as Con Kolivas, used a Bitaxe Gamma 601—a compact mining rig priced at just $158—to mine **Bitcoin block 887,212** on March 10, 2025. As a result, he earned a total reward of **3.15 BTC**, valued at approximately **$263,000** at the time.
This extraordinary event highlights the rare but real possibility that even miners with minimal computational power can succeed in the highly competitive Bitcoin network—thanks to sheer randomness and fortune.
How Bitcoin Mining Works: A Quick Overview
Bitcoin mining is the process by which new transactions are verified and added to the blockchain. Miners use computing power to solve complex cryptographic puzzles, specifically finding a hash below a target value. The first miner to solve the puzzle gets to add the next block to the chain and receives a block reward, currently composed of newly minted Bitcoin plus transaction fees.
The probability of successfully mining a block is directly proportional to the miner’s share of the total network hash rate. Today, the Bitcoin network’s combined computational power exceeds 600 exahashes per second (EH/s), making it extremely difficult for individual or small-scale miners to compete.

The Underdog Rig: Bitaxe Gamma 601
Most serious Bitcoin miners today rely on industrial-grade ASIC (Application-Specific Integrated Circuit) machines, which can cost tens of thousands of dollars and deliver hash rates over 200 terahashes per second (TH/s). In stark contrast, the Bitaxe Gamma 601 operates at just 480 gigahashes per second (GH/s)—over 400 times less powerful than top-tier ASICs.
Despite its modest specs, the Bitaxe 601 has gained popularity among hobbyists and DIY crypto enthusiasts due to its:
- Ultra-low entry cost (~$158)
- Open-source design
- Compact size and low energy consumption
- Educational value for learning about blockchain mechanics
However, under normal circumstances, the expected annual revenue from running a Bitaxe 601 is only around $20**, with electricity costs eating up nearly **$18, leaving a net profit of roughly $3 per year.
The Odds Were Astronomical
Given the current state of the Bitcoin network, the chance of any single low-power device like the Bitaxe 601 mining a block on its own is incredibly slim. According to mining probability calculators, the odds of this happening on any given day are approximately 1 in 4.6 million.
To put this into perspective:
- On average, a miner with this level of hash power would need to continuously operate for over 3,500 years to expect a single successful block find.
- Even deploying hundreds or thousands of such devices would barely move the needle due to the overwhelming dominance of large mining pools.
Yet, randomness governs proof-of-work systems. No matter how small your hash rate, every hash you submit has a non-zero chance of being the winning one.
And on March 10, 2025, Con Kolivas’ device produced the winning hash.
Why This Event Matters for the Crypto Community
While this story is largely about luck, it carries deeper significance for decentralization advocates and small-scale participants in the cryptocurrency space.
Bitcoin was designed to be a peer-to-peer electronic cash system accessible to anyone with internet access. Over time, mining centralization has threatened that ideal, with a handful of large mining farms controlling most of the network’s hash power.
Stories like Kolivas’ remind us that:
- The protocol still works as intended—even tiny contributors have a theoretical chance.
- Open-source hardware projects like Bitaxe help preserve accessibility.
- Randomness ensures no single entity can completely monopolize block discovery.
This moment also reignited interest in decentralized and solo mining efforts, encouraging developers and hobbyists to explore alternative strategies such as proof-of-work lotteries, stratum protocols for micro-miners, and community-driven pooling models that don’t exclude low-hash participants.

Frequently Asked Questions (FAQ)
Can I realistically make money mining Bitcoin with a $158 device?
No—not under current network conditions. Devices like the Bitaxe 601 generate negligible income compared to electricity and opportunity costs. They’re best suited for educational purposes or hobbyist experimentation rather than profit generation.
How did Con Kolivas manage to mine a full block with such low hash power?
Pure statistical luck. While his daily odds were less than 1 in 4.6 million, every hash has an equal chance of solving the puzzle. Over time, even improbable events eventually occur.
Is solo mining still viable in 2025?
For most individuals, no. With network difficulty so high, joining a mining pool significantly increases chances of earning consistent rewards. Solo mining is now mostly symbolic or experimental—except when lightning strikes twice.
What was included in the 3.15 BTC reward?
The reward consisted of 3.125 BTC as the base block subsidy (halving-adjusted) and 0.025 BTC in transaction fees collected from users whose transactions were included in the block.
Could someone replicate this success by buying multiple Bitaxe units?
Extremely unlikely. Even deploying 1,000 units would only bring your daily odds up to about 1 in 4,600—still requiring years of operation for a probable win. Operational costs would far exceed potential returns.
Are there alternatives for small miners who want to participate?
Yes! Some options include:
- Mining alternative cryptocurrencies with lower difficulty
- Participating in merged-mining setups
- Supporting open-source hardware development
- Using testnets for learning and development
Final Thoughts: Luck Meets Legacy
Con Kolivas’ unexpected windfall isn’t just a viral headline—it’s a testament to the enduring spirit of decentralization embedded in Bitcoin’s code. While industrial-scale operations dominate today’s landscape, moments like these prove that the door isn’t completely closed to individuals.
For most people, mining won’t be a path to riches. But for those passionate about technology, autonomy, and digital ownership, stories like this keep the dream alive.
Whether you're a curious beginner or a seasoned crypto observer, remember: in blockchain, even the smallest player can—once in a lifetime—win big.
