How likely is it for a solo miner to beat the odds and win a Bitcoin block?
On June 5, 2025, a solo miner pulled out what could be called impossible: solving a Bitcoin block that united and earned more than $ 330,000 in the Rewards of the Bitcoin block.
And they did this during the most competitive mining conditions in History of Bitcoin.
At this time, Bitcoin’s suffering has been centered as nbits: 0x1b38a1b5. That string refers to the target for miners: the resulting hash of their block should fall under a specific threshold.
The lower the target, the harder the job is. At this level, miners are racing to find a suitable hash that does not have more than 126 trillion possibilities.
That’s what this win has done that is not likely.
Although the miner talking about temporarily raised their hashrate around 259 petahashes per second (pH/s) in a short time, it still has 1 in 3,050 chances of finding a valid block before other people in the global network.
Also, unlike Industrial Mining Farm In the massive setup, this miner is solo, only one machine submits the hashes through solo ckpool.
The miner is likely to hire a massive explosion of computing strength in a short time to make it work. This is a calculated gamble, spike the hashrate, take a shot and hope that Strike Gold.
It worked.
Do you know? Solo CKPool, the platform used in this $ 330,000 win, recorded fewer than 100 solo blocks that won its entire history, making each one a statistically anomaly in a sea of pooled dominance of mining.

What is Bitcoin mining?
Bitcoin mining is the process of verifying transactions and adding them to the blockchain.
Miners transactions in bundle in a block, then repeatedly hahh SHA-256 Double-Hash Falls below the network target.
That target is what nbits and difficulties are being discounted. The first miner to discover a valid hash earns a reward and sees their block that has been adopted, keeps the ledger and releasing the new bitcoin (Btc).
Bitcoin 2025 mining difficulty is explained
Bitcoin aims to produce a block every 10 minutes to balance security, network security and predictable release of Bitcoin.
To maintain the speed of this pace despite the change in the total power of the network computing (hashrate), the protocol adjusts the difficulty to every 2,016 blocks (almost every two weeks).
If block times are always faster than 10 minutesThe suffering is rising; The slower, it decreases.
At the time of Block 899,826, the difficulty is at high time. 
Do you know? In Bitcoin’s mining, the hashrates scale fast: 1 hash is a single prediction, a tehash is a trillion, a petahash is a quadrillion, and an exash is a quintillion. Today, the Bitcoin network process is over 600 exahashes per second; That’s 600 quintillion predictions per second to find the next block.
How a Solo Miner Mined Block 899826
A solo miner using the rented Hash Power temporarily spiked to 259 ph/s and successfully mined Bitcoin Block 899,826 on June 5, 2025, earning more than $ 330,000 in a rare all-or-free win.
I -block 899,826 with a glance
- Confirmed: June 5, 2025, at 03:48 UTC;
- Transactions include: 3,680;
- Total Reward: 3.125 BTC (base subsidy) ~ 0.026 BTC (fee) = ~ 3.151 BTC;
- USD value at the time of confirmation: Approximately $ 330,386.
This block is mined by a single participant by solo ck (Ckpool), a platform that allows individual miners to try to find an entire block on their own, without sharing rewards with others.
According to CKPool Administrator Con Kolivas, only one worker is active in time, strongly suggesting that this is not a standing operation of mining but a temporary setup.
Rented hashpower bitcoin: a tactical hash burst
The miner achieved a peak hashrate around 259 petahashes per second (pH/s), an unusual high figure for a solo miner.
This capacity is unlikely from in-house hardware but sourced by rented hash power from a Cloud mining provider.
Kolivas described the approach as a “take-a-shot” approach: temporary computational power strengthening just enough to increase the possibility of alerting a block before returning to baseline activity.
This type of short -term explosion is a growing tactic among independent miners. Cloud Mining Marketplaces Allow users to rent a hashrate in demand, which can be directed toward pools such as CKPool for solo attempts.
Solo mining bitcoin profit vs pooling
Unlike mining pools, where participants contribute their hashrate and receive a proportional part of each reward, solo mining is all-or nothing.
If a Solo Miner Finding a block, they keep 100% reward. If they don’t, they don’t make money. This is a higher risk approach (especially when the lease capacity), but the potential payment is significantly larger.
In this case, the approach succeeded. By incorporating the targeted timing, rented infrastructure and a solo reward model, the miner has become a narrow statistic opportunity with a successful block confirmation of six numbers.
CKPool Mining Success: Why is it important today
When the block 899,826 is resolved, bitcoin mining difficulty is at high height. That’s what makes this case, and the others are like that, so it’s noteworthy.
This was not the only success of Solo in 2025. Similar wins took place in February. 10 and April 10, each time with block rewards of over $ 300,000.
While rarely, these events suggest a pattern: solo mining remains possible, especially if supported by short -term explosions of rented hash strength.
Implications extend beyond the headlines:
- For small miners, these examples show that temporary access to high performance infrastructure can offer a viable path to I -block rewards (Although it requires capital, timing and technical coordination).
- For Mining poolsThe approach can introduce a hybrid approach in which miners turn between stable pools rewards and occasional solo attempts when conditions are aligned.
- For cloud mining services, the racing points in growing demand from users seeking on-demand, high-capacity rentals aimed at short-term solo techniques.
While large-scale operations are still dominant in the network, strategic plays of solo have carved the space, proving that even under the difficulty of the record, individual actors can still produce an effect.
What is Solo Bitcoin Miner’s win about Bitcoin Mining
Events like this feature increased flexibility of bitcoin mining.
While increasing difficulty suggests a mature and highly safe network, the ongoing possibility of solo mining shows how new tools and tactics are reshaping to participate.
Platforms like Solo Ckpool, previously seen as a niche lottery-miner plaything, support now rare but significant Lock the win.
At the same time, cloud-based power-based power markets enable miners without a wide infrastructure to engage in targeted, short-term techniques that can result in returning returns.
If these solo wins become more usually remains unsure. They rely on a mix of timing, accessing capital and technical implementation that is difficult to copy. However, their existence is noteworthy, which offers a counter to the narrative that mining can only be accessible to industrial players.
In the bigger picture, what is used to be a matter of raw computational power also becomes a question of approach, flexibility and access to infrastructure.
The odds remain long, but this case shows that they are not zero. That’s just the one who will keep others try.
