A solo Bitcoin miner operating through CKPool solved block 943,411 on April 3 and earned 3.139 BTC, worth about $210,000, from the 3.125 BTC block subsidy and roughly 0.014 BTC in transaction fees. The miner’s setup ran at about 230 TH/s while Bitcoin’s network hashrate was near 1 zettahash per second, giving the operation only a tiny share of global hashpower. CKPool developer Con Kolivas said the miner’s odds were about 1 in 28,000 per day, while Bitcoin Archive analyst Archie said a miner at that level would statistically win about once every 76 years. The block was the 312th solo block mined through CKPool and ended a 33-day stretch since the previous solo success on February 28. The report also noted other recent low-probability solo mining wins and said major public miners including Riot Platforms and MARA Holdings have recently sold large amounts of BTC to raise cash.
