In the unpredictable world of cryptocurrency mining, one independent miner recently defied astronomical odds and struck digital gold — not with a warehouse full of high-end ASIC machines, but with a tiny, $158 mining device small enough to fit in the palm of your hand.
This unexpected success story centers around Con Kolivas, a solo Bitcoin miner who used a Bitaxe Gamma 601 — a compact, open-source mining rig — to successfully mine Bitcoin block 887,212 on March 10, 2025, earning a full block reward of 3.15 BTC, valued at approximately $263,000 at the time.
The win has sent ripples through the crypto community, not just for the sheer luck involved, but as a rare real-world demonstration that even in today’s hyper-competitive mining landscape, the decentralized spirit of Bitcoin still holds a glimmer of possibility for individual participants.
How Did a $158 Miner Beat the Odds?
Bitcoin mining has evolved dramatically since its early days when hobbyists could mine coins using home computers. Today, the network's total computational power — known as hashrate — is so immense that only specialized, industrial-grade ASIC miners are considered viable for consistent returns.
These professional rigs can cost upwards of $10,000, consume massive amounts of electricity, and are typically deployed in large-scale mining farms across regions with cheap power.
Enter the Bitaxe Gamma 601, a miniature mining device developed by the open-source hardware community. Priced at just $158, it delivers a modest 480 GH/s (gigahashes per second) of hashing power — a fraction of what top-tier ASICs like the Antminer S19 offer (around 230,000 GH/s).

Given these specs, the daily probability of a single Bitaxe 601 finding a valid Bitcoin block is estimated at 1 in 4.6 million. In practical terms, a miner would need to run this device continuously for an average of over 3,500 years to expect one successful block discovery.
Yet, Con Kolivas did it — not through brute force, but through persistence and extraordinary luck.
The Block That Defied Statistics
On March 10, 2025, Kolivas’ Bitaxe successfully solved the cryptographic puzzle for block 887,212, broadcasting the correct hash before any other miner in the global network. As the first to validate the block, he received:
- 3.125 BTC — the base block subsidy (post-halving reward)
- 0.025 BTC — in transaction fees from users included in the block
- Total: 3.15 BTC ≈ $263,000
This event wasn’t a fluke in code or a network error — it was fully verified and recorded on the public blockchain. While solo mining with low-hashrate devices is statistically negligible, Bitcoin’s consensus algorithm doesn’t discriminate based on hardware size. If you find the correct nonce, you get the reward — no matter how unlikely it seems.
“This is a reminder,” Kolivas later commented, “that Bitcoin remains permissionless and open. Even with minimal resources, participation is possible. It’s not profitable — but every now and then, lightning strikes.”
Why This Matters for Decentralization
Bitcoin’s design principle hinges on decentralization. The more geographically and economically diverse the miner base, the more resilient the network becomes against centralization and potential attacks.
Large mining pools and corporate data centers now dominate over 90% of the network hashrate. This concentration raises concerns about single points of failure and potential collusion.
Devices like the Bitaxe Gamma 601 represent a counter-movement — DIY, affordable entry points into mining that keep the door open for individuals. Though they won’t generate regular income, they allow enthusiasts to:
- Learn how Proof-of-Work works firsthand
- Contribute to network security (even marginally)
- Experience the thrill of true ownership and participation
As one developer from the Bitaxe community noted:
“We’re not building these for profit. We’re building them so anyone can say, ‘I mined a block on Bitcoin,’ even if it happens once in a lifetime.”
The Reality of Profitability
Let’s be clear: mining Bitcoin with a $158 pocket miner is not a get-rich-quick scheme — far from it.
Based on current network difficulty and electricity costs:
- Annual revenue: ~$20 in BTC rewards
- Power consumption: ~$18/year (at average U.S. rates)
- Net profit: ~$3 per year
That means it would take over 50 years of continuous operation to recoup the initial hardware cost — assuming Bitcoin’s price and network conditions remain stable.

For most people, purchasing a Bitaxe solely for financial return makes little sense. However, for educators, tinkerers, and crypto idealists, it serves as a powerful educational tool and symbolic gesture toward decentralization.
Could This Happen Again?
Technically, yes — but don’t bet on it.
The odds remain staggeringly low:
- 1 in 4.6 million chance per day
- Less than a 0.1% chance of success within a decade
- Requires constant uptime and perfect connectivity
Still, as long as Bitcoin exists and its protocol remains unchanged, every hash submitted counts — regardless of source.
And while industrial miners operate at scale, stories like Kolivas’ remind us that Bitcoin’s lottery-like reward system still allows for miracles.
Frequently Asked Questions (FAQ)
Can I realistically mine Bitcoin with a small device like Bitaxe?
No, not for profit. The Bitaxe is best viewed as an educational or experimental project. Earnings are negligible compared to electricity and time costs.
Is solo mining still possible in 2025?
Yes, but extremely rare. Most miners join pools to combine hashpower and receive frequent micro-payments. Solo mining only pays off when you find an entire block — which could take centuries with low-end gear.
Why use open-source miners like Bitaxe?
They promote transparency, learning, and decentralization. Users can inspect firmware, modify settings, and avoid reliance on proprietary black-box systems from major manufacturers.
Does this mean big mining farms are obsolete?
Absolutely not. Large-scale operations remain essential for maintaining network security and processing transactions efficiently. They provide the vast majority of hashrate needed to keep Bitcoin secure.
Could future tech make small miners competitive again?
Unlikely under current Proof-of-Work rules. Unless there’s a radical drop in network difficulty or breakthrough in energy-efficient computing, ASIC dominance will continue.
Is mining still worth exploring for beginners?
Yes — especially through simulators or testnet environments. For hands-on learners, affordable miners like Bitaxe offer unmatched insight into how blockchain validation truly works.

Final Thoughts: A Symbolic Win for Crypto Ideals
Con Kolivas’ $263,000 windfall isn’t just a viral headline — it’s a testament to Bitcoin’s enduring promise: anyone, anywhere, can participate.
While economic reality favors industrial players, the protocol itself remains blind to size. Luck may have played the biggest role here, but so did access, openness, and the belief that even a tiny contribution matters.
In an era where centralization looms large, this moment shines as a beacon of what Bitcoin was built for — decentralized opportunity, one hash at a time.
