A second solo Bitcoin miner has struck gold this week, solving a full block on April 9, 2026 (block 944,306) and earning approximately 3.128 BTC—worth around $222,000–$225,000 at prevailing prices including the block subsidy and transaction fees.
This win came via CKPool’s solo mining service. The miner operated with just ~70 TH/s of hashpower—roughly equivalent to one older-generation ASIC miner like a 2019-era Antminer S17+. That’s a tiny fraction of the Bitcoin network’s total hashrate around 950 EH/s at the time. Estimates put the probability at roughly 1 in 100,000 per block for that hashrate level, or something akin to a once-in-300-years event on average. Yet it happened.
This marks the second solo win in about 10 days on CKPool. The prior one around April 2, block ~943,411 delivered ~3.139 BTC worth roughly $210,000 with ~250 TH/s. These back-to-back events highlight Bitcoin’s mining lottery nature: even in a network dominated by industrial-scale pools, individual or small-scale miners can still get extraordinarily lucky and claim the entire reward without sharing it.
Solo mining successes remain rare overall—only a couple dozen full blocks per year in recent periods despite thousands of blocks mined daily. Earlier 2026 examples included wins worth ~$300,000 each in January, and smaller setups even as low as a few TH/s have hit before. These stories often go viral in the Bitcoin community as proof that decentralization isn’t dead, even as large operations control most hashpower.

The back-to-back solo Bitcoin mining wins in early April 2026 have sparked discussions across the crypto community about several key impacts. These events serve as powerful, real-world proof that Bitcoin’s proof-of-work system still allows individual or small-scale participants to compete successfully, even against industrial giants.
With the winning miner operating just ~70 TH/s roughly one outdated ASIC like an Antminer S17+ and ~0.000007% of the network’s ~950 EH/s–1 ZH/s hashrate, the win underscores that no single entity or pool fully controls block production. They counter narratives of extreme centralization, where a few large pools dominate. Solo successes, though rare only ~20–22 verified solo blocks in the prior 12 months out of ~52,000+ total blocks, act as health indicators for the network’s openness.
Platforms like CKPool see renewed interest. Some view solo mining as a fun, sovereign alternative to pools, despite the high variance. A few even argue it’s better than pool mining for those chasing full rewards, especially with accessible hardware or short-term hashrate rentals.
Large pools and industrial operations still command the vast majority of network power. Solo wins represent a tiny fraction of blocks overall. However, repeated small-scale victories including multiple in short periods slightly diversify block producers and reduce reliance on any one operator for transaction selection. Mining has trended toward consolidation due to economies of scale, high energy costs, and post-halving economics.
Yet these outliers show that luck can occasionally trump size. Some analysts note that temporary hashrate dips can mathematically increase solo odds slightly, but this is more a symptom of profitability challenges than a deliberate decentralization win. The ~3.128 BTC reward delivered ~$222K at ~$71K BTC prices—far exceeding the cost of a single older machine or even short-term rental setups.
These demonstrate extreme ROI potential but remain statistically improbable (1-in-100,000 daily odds for 70 TH/s equates to once every ~300 years on average). Highlights the high-risk, high-reward nature of solo vs. pooled mining. Pools offer predictable payouts; solo offers full upside with near-zero expected value for small operators.
It may encourage experimentation with tools like hashrate rentals or home setups, though most serious miners stick to pools for cash flow stability. No negative impact—Bitcoin’s difficulty adjustment currently ~139T, with a slight drop expected mid-April keeps the chain secure regardless of who finds blocks. Solo wins don’t weaken security; they affirm the protocol’s design.
Some ask if solo mining is still worth it in 2026’s high-difficulty environment. Great for lottery-ticket enthusiasts or ideological purists, but not a reliable business model. Over the past year, solo miners collectively earned ~60–70 BTC across wins, averaging one every ~15–18 days across tracked setups.
The impacts are primarily narrative and inspirational rather than structural. They don’t overhaul mining economics or hashrate concentration but vividly illustrate Bitcoin’s core promise: anyone with electricity, hardware, and extraordinary luck can still participate at the highest level. For most, joining a pool remains the practical path; for a few dreamers, these wins keep the solo dream alive.
Congrats to the lucky miner(s)—a real David-vs-Goliath moment. If you’re solo mining yourself, these wins are inspirational but statistically closer to winning the actual lottery than a reliable strategy. Most participants join pools for steadier payouts. Bitcoin’s price has been hovering in the $70K–$72K range recently, making these full-block rewards land in the low-to-mid six figures USD.
Bithumb In Chase to Recover ~7 BTC from Massive February Payout Error
Bithumb, South Korea’s second-largest cryptocurrency exchange, has initiated legal action to recover the remaining ~7 BTC worth roughly $500,000 at current prices from a massive February 2026 payout error that briefly distributed about 620,000 BTC—valued at around $40–44 billion—due to a staff input mistake.
On February 6, 2026, during a promotional event, Bithumb intended to reward 249 users with a small amount in Korean won (KRW)—totaling roughly 620,000 KRW; a few hundred USD overall, or about 2,000 KRW/~$1.40–$1.50 per winner in some reports. A staff member accidentally entered BTC instead of KRW in the system, causing the platform’s internal ledgers to credit users with 620,000 Bitcoin instead.
This created the appearance of enormous balances; far exceeding Bithumb’s actual holdings—reportedly over 13 times more BTC than the exchange owned. The error briefly triggered a ~10–17% drop in Bitcoin’s price on the platform and raised systemic concerns. Bithumb quickly noticed the mistake, apologized, reversed most of the erroneous credits on its books, and recovered the vast majority reportedly 99.7% of the Bitcoin.
However, a small portion—initially around $9 million worth, now narrowed to about 7 BTC—remained with users who either sold, transferred, or refused to return the funds. South Korean regulators including the Financial Supervisory Service urged users to return the unjust gains, warning of potential catastrophe and possible legal consequences for those who didn’t comply.
Bithumb has filed for a provisional seizure; a court-approved asset freeze targeting accounts holding the remaining ~7 BTC. This is a pre-lawsuit measure to secure the assets while a formal civil suit proceeds. The exchange is focusing on a small group of users who have not voluntarily returned the Bitcoin. Most users reportedly cooperated and returned the funds.
Bithumb prefers voluntary returns to avoid full civil litigation, partly because Korean civil law might require returning the original asset (BTC) rather than just its cash equivalent at the time of the error—which could complicate things if prices have moved or coins were sold and spent. The exchange has cited internal system flaws that allowed the error, and it faces separate regulatory scrutiny and potential sanctions over inadequate controls.
The incident highlighted operational risks in centralized crypto exchanges, including human error, weak input validation, and the challenges of reversing on-chain or ledger entries once funds move. It also sparked discussions in South Korea about tighter regulations for exchanges and whether keeping mistaken funds could lead to civil or even criminal liability in some cases.
Bithumb emphasized that customer assets were never actually at risk of loss beyond the accounting error, and it moved quickly to contain the issue. Still, the case serves as a reminder of the differences between centralized platforms; where operators can often reverse or freeze entries and decentralized systems, where fat-finger mistakes are irreversible without user cooperation or smart-contract safeguards.
695 accounts were temporarily credited with massive balances. Most cooperated with reversals. Users who sold before the freeze faced obligations to return equivalent value—sometimes requiring repurchase at current potentially higher BTC prices under unjust enrichment principles. Bithumb offered compensation, including 110% reimbursement for panic sellers in some cases, plus fee waivers. Estimated direct user losses from selling were small ~?1 billion or $760K.
The exchange covered shortfalls from its reserves initially ~1,788 BTC sold, later narrowed. No customer funds were permanently lost, and deposits and withdrawals continued for unaffected users. However, the incident damaged trust and exposed internal control weaknesses.
