Winning odds are only 0.00357%! “SOLO miners” hit the block with incredible luck, making a cool profit of 3.139 bitcoins

This is probably the most envied “little shrimp beats the big whale” story in recent times. A lone “SOLO miner” managed to win the “once in a century” jackpot by relying on its minuscule computing power and a 0.00357% chance of hitting the winning lottery, successfully mining Bitcoin block #943,411, and pocketing 3.139 BTC (about $210,000) all by itself. According to data from the blockchain explorer Mempool, this lucky miner on April 3 successfully mined a block via the solo mining platform CKpool, earning a block reward of 3.125 BTC, plus transaction fees of 0.014 BTC ($940), bringing total payouts to 3.139 BTC (approximately $210,108). CKpool is an established anonymous solo mining pool founded in 2014. It allows individual miners to keep the full block reward after deducting a 2% service fee. In response, CKpool developer Con Kolivas also posted on the community platform X to congratulate: “Congratulations to the miner at address bc1q~lun3, who mined the 312th solo block with only 230 TH/s of hash rate!” He added that for miners of this size, the chance of successfully mining a block each day is only about 1/28,000 (0.00357%). As of April 2, the estimated total network hash rate for Bitcoin is 1 ZH/s. By comparison, this lucky miner has only 230 TH/s, accounting for about 0.00002% of the network hash rate. Judging from the data performance, it looks more like a few home-grade ASIC mining machines set up under someone’s own roof. According to data from the solo miner tracking platform Bennet, this is the first time CKpool has seen a solo miner successfully mine a block since February 28, ending a drought period lasting 33 days. Over the past 12 months, solo mining pools have mined only 20 Bitcoin blocks in total, producing 62.96 BTC combined. On average, a solo block appeared every 18.7 days, and the longest gap reached 58 days. Why do some people still choose “SOLO mining”? In the vast Bitcoin network, because the chance of solo mining successfully winning the block reward is extremely low, smaller miners typically choose to join a “mining pool.” The goal is to pool computing power to mine together, then share rewards according to contribution ratio, trading off for stable and predictable income. Even so, there are always some miners who prefer going it alone. They take a gamble through solo mining pools, all for that “winner takes all” block reward. This model avoids the pool’s fee cut. Although the odds of success are slim, once you hit the jackpot, it’s equivalent to winning a life-changing lottery ticket.
