- Two solo Bitcoin miners using CKPool recently solved blocks worth about $210,000 and $225,000 despite minuscule hashrate shares.
- One miner operated around 230 TH/s and another near 70 TH/s, facing odds ranging from 1 in 28,000 to 1 in 100,000 per day.
- These blocks were the 312th and 313th solo wins recorded by CKPool since 2014, in a context where solo blocks remain below 0.05% of the total.
- Cases like these highlight Bitcoin’s probabilistic, decentralized design while underlining that solo mining is still high-risk and rarely profitable.
Against overwhelming odds, a lone Bitcoin miner running modest hardware has once again managed to secure a full block reward, reviving one of the most talked‑about narratives in the crypto world: the possibility that a small, independent operator can still walk away with a six‑figure payday. Within just a few days, two different solo miners connected to CKPool validated blocks worth roughly $210,000 and $225,000 in BTC, despite contributing only a microscopic fraction of Bitcoin’s total computing power.
These unusual successes have sparked fresh debate around the role of solo mining in an industry increasingly dominated by industrial‑scale farms and public mining companies. While the numbers confirm that the odds are brutally low, the fact that such wins keep appearing — even if rarely — underlines a key feature of Bitcoin’s proof‑of‑work: statistically, anyone with hashpower can still hit the jackpot, even if most never will.
Two solo block wins in a week: how the story unfolded
On 3 April 2026, a solo miner linked to Solo CKPool managed to solve block 943,411. Operating at roughly 230 terahashes per second (TH/s), this miner controlled only about 0.00002% of the network’s estimated 1 zetahash per second (ZH/s) hashrate at the time. In other words, their contribution was barely a rounding error on most dashboards.
The reward, however, was anything but small. The rig captured 3.139 BTC in total — 3.125 BTC from the standard block subsidy plus around 0.014 BTC in transaction fees — valued at roughly $210,000 at prevailing prices. All of this was obtained while mining in CKPool’s solo mode, which allows miners to keep the entire block reward minus a 2% fee paid to the service.
The win was confirmed publicly by CKPool developer Con Kolivas, who posted on X that a miner with about 230 TH/s had solved the block. Kolivas estimated that with that level of hashrate, the miner had around a 1 in 28,000 chance per day of discovering a block. Statistically, that implies a typical waiting time of more than seven decades for a single hit.
Just days later, on 9 April 2026, a second solo success hit the headlines. Another independent miner, this time running about 70 TH/s of hashpower, validated block 944,306 while connected to Solo CKPool. Their setup represented only around 0.00000667% of Bitcoin’s total estimated hash rate, showing how tiny a home‑scale operation can be relative to the network as a whole.
The reward for that block came in at 3.125 BTC plus fees, for a combined payout in the region of $222,000‑$225,000 depending on the BTC price at the moment of settlement. CKPool’s creator highlighted the scale of the feat by noting that a miner with 70 TH/s faces odds of about 1 in 100,000 per day of solving a block — roughly equivalent to succeeding once every 300 years on average.
What these wins say about CKPool and solo mining
The two blocks described above are part of a longer track record. According to data shared by CKPool, the 3 April win was recorded as the 312th solo block mined through the service since it launched in 2014, while the 9 April success was counted as number 313. For a platform that has been active for over a decade, those numbers underscore how rare solo wins really are in practice.
CKPool operates an unorthodox middle ground between pure solo mining and traditional pools. Users connect their ASICs to Solo CKPool, but unlike conventional pools where rewards are shared proportionally among participants, solo miners on CKPool keep the entire block reward if they are the one to find it. The service charges a 2% fee only when a block is actually solved, allowing miners to avoid having to maintain their own full node infrastructure or handle all of the bandwidth and storage requirements themselves.
From an economic perspective, this model offers a high‑variance, high‑risk payoff structure. Instead of receiving small, frequent payouts as in a standard pool, solo miners face long periods of zero income punctuated by the extremely unlikely possibility of a huge windfall. The recent wins highlight how this setup can be attractive for enthusiasts or ideological miners who value the chance of a full block reward over stable cash flow.
In the past twelve months, solo pools have collectively found only about 20 Bitcoin blocks, distributing close to 62.96 BTC in rewards. That figure translates to roughly one solo block every 18‑19 days on average, with some gaps stretching out close to two months. Compared with the more than 52,000 blocks mined across the entire network over a year, solo mining still accounts for well under 0.05% of total block production.
Despite these tiny percentages, the April sequence — two solo wins in just seven days via the same service — has drawn attention precisely because it clashes with people’s intuitive sense of probability. In reality, Bitcoin’s proof‑of‑work is inherently probabilistic, so even events with long odds can and do occur, as long as enough miners continue to try their luck.
Hashrate, probability and the long‑shot nature of solo wins
To understand why these cases are so rare, it helps to look at how hashrate translates into chances of finding a block. The Bitcoin network targets an average of one block every 10 minutes, around 144 blocks per day. Each miner’s probability of solving a block is essentially the ratio of their personal hashrate to the global network hashrate.
In the case of the 230 TH/s miner, the network was estimated around 1 ZH/s, or one trillion TH/s. That means the miner owned roughly 0.00002% of the total. On any given block, their chance of success is therefore 0.0000002 in decimal form, or about 1 in 5 million. Aggregated over a full day of 144 blocks, that becomes the previously cited 1 in 28,000 chance.
For the 70 TH/s operator, the picture is even more extreme. At around 70 TH/s, the miner was contributing only around 0.00000667% of the global hashrate, making their probability of solving any individual block vanishingly small. Rolled up across a day, it results in that now‑famous figure of roughly 1 in 100,000. Over longer time horizons, the expected waiting time runs into centuries, which is why such wins are commonly compared to winning a lottery.
For hobbyist rigs at even lower power levels, the math becomes more daunting. A small setup around 6 TH/s — something you might see in a home experiment using a compact ASIC — may face odds on the order of 1 in 170-180 million per block. Statistically, the expected wait time can stretch into thousands of years of continuous operation. Even stepping up to 1 petahash per second (PH/s) often leaves would‑be solo miners facing decades between expected wins.
Given these figures, it is not surprising that the vast majority of individual miners choose pooled mining, where their hashrate is aggregated with others and rewards are shared proportionally. That model smooths out income and makes it easier to cover ongoing costs like electricity and maintenance, even though it eliminates the dream of a single, huge payout.
Old ASICs, new life: what hardware are these solo miners using?
One of the more intriguing angles in the recent $225,000 win is the hardware profile suggested by the miner’s hashrate. According to data shared by Con Kolivas, the successful rig’s power fluctuated between roughly 62 and 73 TH/s. That performance range closely matches older ASIC models launched around 2020‑2021, such as Bitmain’s Antminer S19 series, MicroBT’s Whatsminer M32, or Canaan’s Avalon 1166 Pro.
When these devices first hit the market, they were state‑of‑the‑art machines used by large industrial miners. Fast forward several years, and the landscape has shifted dramatically. With today’s top‑end ASICs pushing beyond 800 TH/s per unit and the global network hashrate soaring, earlier generations like the S19 are often considered uncompetitive in large‑scale operations.
For example, estimates for an Antminer S19 Pro running at standard efficiency and paying around $0.10 per kWh for electricity show net daily losses of roughly $4 at current difficulty and price levels. In a conventional industrial setup, that kind of performance simply does not make economic sense, which is why many big farms have retired or resold these models.
However, the recent solo win suggests a different story: older ASICs do not necessarily disappear when they leave industrial farms. Instead, some of them find a second life in smaller, more flexible environments. Hobbyists or small operators who have access to cheaper power — or who are willing to treat mining partly as an ideological pursuit — may still run these machines, hoping to offset some of their costs and, in extremely rare cases, score a life‑changing block.
Crucially, though, this doesn’t change the fundamental statistics. Running legacy hardware in solo mode remains a strategy where successful stories are the exception that proves the rule. For every miner who lands a six‑figure reward, countless others will run equipment for months or years without ever seeing a block of their own.
Industrial giants versus home rigs: a stark contrast
The contrast between solo winners and industrial miners becomes even clearer when comparing raw hashrate figures. Publicly listed companies like Riot Platforms report operating more than 30 exahashes per second (EH/s) on their own. That’s 30 million TH/s — around 130,000 times the 230 TH/s of the April solo winner and an even greater multiple over the 70 TH/s setup.
At these scales, large operators can expect to find numerous blocks per day, smoothing revenue and making it possible to plan capital expenditures, electricity contracts and infrastructure upgrades. Their business models revolve around economies of scale, access to low‑cost power and constant optimization, rather than hoping for a lucky break.
Interestingly, the latest solo victories landed during a period when some of the biggest miners were actively selling off their Bitcoin holdings. Riot Platforms, for example, recently sold around $250 million worth of BTC, while Marathon Digital and other firms have also liquidated significant portions of their treasuries, sometimes to pivot resources toward adjacent sectors like AI infrastructure.
This divergence reinforces a curious narrative: while corporate miners manage balance sheets and shed BTC to cope with volatile market conditions and rising costs, a handful of small, independent players are getting their turn in the spotlight with outsized rewards. It doesn’t change the overall economics of mining, but it does offer a striking snapshot of how individual experience can differ wildly from industry‑level trends.
From a decentralization standpoint, these stories are often taken as a reminder that Bitcoin’s design still allows for grassroots participation. Even if the practical power dynamics overwhelmingly favor large farms and pools, the protocol does not hard‑code any advantage beyond sheer hashrate. In principle, a handful of older ASICs in a garage can compete with a centralized data center, albeit with odds stacked heavily against the smaller player.
Why solo mining still captures the imagination
Part of the fascination with these events comes from how closely they align with Bitcoin’s early, more romanticized era. In the first years after launch, it was common for individuals to mine Bitcoin on CPUs or GPUs from home, with a realistic chance of finding blocks on their own. Over time, the arrival of specialized ASICs and the explosion in hashrate shifted mining into an arms race, gradually crowding out smaller players.
Today, solo mining is often viewed less as a rational business and more as a mix of ideology, experimentation and lottery ticket. Miners who choose this path accept that their probability of success is tiny but value the idea of participating directly in the consensus process and potentially keeping a full block reward if luck is on their side.
The April wins underscore that this mindset still has a foothold. The fact that a miner with 230 TH/s or even 70 TH/s can walk away with more than $200,000 in a single block resonates strongly on social media and crypto forums. These stories are frequently held up as examples of David‑versus‑Goliath moments, even if, statistically, Goliath still wins virtually all of the time.
At the same time, more sober voices point out that survivorship bias plays a huge role in how these stories are perceived. The few miners who succeed become headlines; the vast majority who never hit a block remain invisible. That asymmetry can easily create the impression that solo wins are more common than they really are.
For newcomers considering solo mining, the key takeaway is that these successes should be seen less as templates to emulate and more as educational examples of how probabilistic systems behave. They show what is possible in theory, not what is likely in practice. Any decision to mine solo still needs to factor in electricity prices, hardware costs, maintenance, and the very real chance of never seeing a direct block reward.
The state of Bitcoin, block rewards and network dynamics
These solo wins also arrive at a time when broader network and market dynamics are shifting. Recent data showed Bitcoin’s hashrate jumping by almost 15% within a 24‑hour span, reflecting ongoing investment in new hardware and infrastructure. As hashrate rises, so does the difficulty of the proof‑of‑work puzzles, making each individual hash less likely to succeed.
On the monetary side, the current block subsidy stands at 3.125 BTC per block following the latest halving. Every four years or so, this reward is cut in half, reducing the number of new bitcoins entering circulation. For miners, that means revenue per block declines over time unless offset by higher BTC prices or greater efficiency. The solo blocks mentioned here both earned the 3.125 BTC subsidy plus transaction fees, which pushed their total value into the low‑ to mid‑$200,000 range at spot prices.
Market conditions at the time were relatively strong. Bitcoin was trading around $72,000 per coin, roughly 1.2% higher over the previous 24 hours according to some reports. Even so, that price remained significantly below the asset’s all‑time high, which some sources place near $126,000 from October of the prior year. That gap underscores how sensitive mining profitability can be to BTC’s market performance.
In this context, many large miners have been rebalancing their strategies, including selling parts of their BTC treasuries or diversifying into other compute‑intensive sectors like artificial intelligence workloads. While these moves attract attention from investors and analysts, they also highlight just how different the risk profile of industrial miners is from that of a single hobbyist betting on a solo block.
For the network itself, the solo wins are statistically negligible but symbolically potent. They do not materially alter the distribution of hashrate or block production, yet they serve as periodic reminders that Bitcoin’s rules still allow small players to compete, even if just on the fringes.
Put together, the recent stories of lone miners pocketing six‑figure rewards with 70 TH/s and 230 TH/s help paint a nuanced picture of Bitcoin mining today: a system where industrial‑scale operations overwhelmingly dominate, yet where the protocol’s probabilistic nature occasionally hands a winning ticket to someone running what, in network terms, amounts to a drop of water in an ocean of hashpower.
