Imagine yourself alone in front of your mining rig, with only one objective: to find that famous "nonce", to obtain the block reward, and to hope that an improbable stroke of luck occurs.
This is exactly what a solo miner experienced on November 21, 2025, when he managed to mine block number 924,569 of the Bitcoin network, pocketing 3.146 BTC, or about $265,000 at the current price.
And he's not the only lucky one this year. The year 2025 will have been marked by a series of "statistical miracles": more than five solo miners achieved the improbable feat of finding a block entirely on their own, each winning rewards ranging from $200,000 to over $300,000.
In a network dominated by mega mining farms and industrial pools, these individual successes are flashes of brilliance in the night, rare certainly but spectacular.
In this article, we will break down this fascinating lottery phenomenon:
- what is the solo mining today ?
- Do we really have a chance of winning?
- Who are these lucky people of 2025?
- What machines offer hope?
- And most importantly: is this a valid strategy or just a romanticized dream?
Welcome to a world where, sometimes, David manages to beat Goliath.
What is solo mining?
Solo mining, in its purest definition, consists of mining blocks without joining a farm. You mine alone, with your own machines, and if you find a block, you keep 100% of the reward: the 3,125 BTC from the 2024 halving, plus transaction fees (which can add several hundred or thousands of dollars depending on congestion).
It's a bit like buying a single lottery ticket against thousands of industrial reels. You're playing alone against the entire network, and your hardware needs to be sufficient to solve a block before everyone else.
Put like that, it seems impossible. And, statistically, it almost is.
However…
Who managed to mine alone in 2025?
The examples from 2025 are truly admirable, even fascinating. Several solo miners have managed to extract a complete block despite the increase in the global hashrate (which exceeded 1,200 EH/s this year).
And to begin with, there's this very recent case: a solo miner who managed to break a boulder with " barely "1,2 TH/s of computing power. At the beginning of the year, in February, a lone miner mined block 883181, earning over 3,125 BTC. In July, another miner found block 903883, earning approximately $349,000 with only 2,3 PH/s of computing power."
Other blocks (including 907283, the 910440(913632) were discovered by individuals working via mining platforms such as Solo CKPoolThe platform provides the necessary infrastructure for independent miners to connect directly to the Bitcoin network. They can then receive the full reward if they find a block on their own.
Each time, the same scenario: an isolated miner, with little power compared to the giants, hits the jackpot and captures the entire reward.
These stories are rare, certainly, but they are enough to nourish an entire mythology: that of the David mining which, from time to time, manages to hit the block before the Goliath industrial.
Do we really have a chance of winning?
You probably want to dream, just like us, but let's be honest: the probability is infinitesimal. But infinitesimal doesn't mean nonexistent. That's the subtle point.
In practice, even a small ASIC machine can theoretically find a block. According to SoloSatoshi, a shop that sells minor solos, the lucky November miner might have used a " Bitaxe Gamma"
Indeed, a Bitaxe Gamma allows speeds of up to 1,2 TH/s. The higher-end version, namely a NerdQaxe++ allows reaching 6 TH/s.
That's the very nature of Proof-of-Work: every hash, even a tiny one, is a ticket in Bitcoin's cosmic lottery. It really is a matter of chance.
In fact, you have to understand the scale. With a modern ASIC, you can contribute a few hundred TH/s. The entire network, however, is now expressed in exahashes, which are billions of times larger.
Finding a block with a single machine is like winning the lottery… except some players win several times a year. It's not impossible: it's just statistically unreasonable.
It is precisely this contrast between improbable et made which makes these stories so fascinating.
Which machines offer hope for a block?
By 2025, solo mining with a small GPU or an old ASIC is pointless: you'll never find a block that way. To have even the slightest chance, you need at least recent, high-performance hardware such as:
- Antminer S21 Hydro / S21 Pro, around 300–470 TH/s
- Whatsminer M60 / M63, varying between 200 and 300 TH/s
- And in rare cases, some miners operate multiple machines to achieve 1 to 5 PH/s
Even with that, the probability remains minuscule. Furthermore, it's essential to be able to mine these machines from home, not via host mining.
That's why some prefer solo miners, trying their luck in the great lottery that is solo bitcoin mining.
Why do some minors still try?
There is a logic behind solo mining, even if it seems irrational.
- First, there is the aspect sovereigntySome miners hate the idea of giving their computing power to a pool, even a decentralized one like Ocean for example, and want to mine on their own, on principle.
- Then there is the aspect romantic Finding a block on your own is like discovering gold in a river already exploited by industrial machines. It's a mythical feat.
Finally, some miners have access to virtually free electricity in certain regions, or access to extremely low electricity rates (hydroelectric, solar, recovered heat, local energy surplus). In these cases, trying their luck has no real marginal cost.
Solo mining: miracle or real strategy?
If you're planning to try your hand at solo mining to hit the jackpot, cross your fingers. Solo mining isn't a reliable income strategy. It's a gamble, a risky attempt, almost a philosophical endeavor.
But this gamble exists, and sometimes it pays off.
This phenomenon shows above all something very important for Bitcoin: despite the centralization of the hashrate in industrial farms, the network has not yet crushed the individual.
A lone miner can still beat the giants. A simple ASIC can still, on a lucky day, produce a block worth hundreds of thousands of dollars.
Bitcoin's permissionlessness, its resistance to capture, its openness to all... all of this materializes in these exploits.
Final verdict: Should you give it a try yourself?
The solo mining boom in 2025 is not a "return" of artisanal mining, but rather a rebirth of what it represented: the possibility, however small, that someone in their living room could grab a block and make history.
It's rare, it's irrational, it's economically questionable…
But it's also fundamentally Bitcoin.
For the majority of users, pool mining remains the only sensible option.
For dreamers, sovereigns, enthusiasts, purists… solo mining remains a romantic gamble, an act of freedom.
And as long as he remains possibleBitcoin will remain true to its original promise:
an open network for everyone, where even the smallest players retain a tiny but real chance of winning against the giants.
