A solo Bitcoin miner beat all the odds and won the massive $349k jackpot. Notably, the winning against bigger institutions requires too much precision and some even say luck, as his odds of winning were just 0.004%. On the other side, the crypto market is also witnessing some uptrend following Trump’s Big Beautiful Bill and other milestones.
Solo Bitcoin Miner Mines 903883 Block Winning $349k
The anonymous Bitcoin miner succeeded in mining an entire block number 903883. The reward for mining this entire block was 3.173 BTC, resulting in the individual making $349,028 at the current BTC price of $108.4k.
Crypto analysts, the Bitcoin Historian notes this epic milestone as it’s a rare event since bigger corporations and groups succeed with most due to high computation power and other factors. Notably, the miner used only 2.3 peahashes per second (PH/s) of hash power, and the mining occurred through the CKpool solo mining pool.
CoinTelegraph noted that the miner of this size has only 1 in 2,800 chances of solving an entire block by himself. That means it happens only once in 8 years on average, making the odds of the Solo miner winning just 0.004% (1 in 375,300).
Besides, winning an entire block would require the miner to have 166,000 TH/s of hash power, equivalent to 500 Antminer S21 Hydro units. This would cost the individual millions of dollars in upfront investment alone. Not to forget the high electricity charges and limitations.
Other Solo Bitcoin Miner Milestones
Although the odds of a solo BTC miner winning are quite low, many such milestones have been noted in the past. In June 2025, a miner succeeded in mining the 899,826 block and earned $330,000 in reward. Before this, another miner mined 883,181 block in February 2025, earning nearly $300,000.
Talking about the individual BTC trader milestone, JohnGalt has also made big on this digital asset. With the Bitcoin Gold bar bought in 2012, he turned a $500 investment into $10 million after redeeming it this year. During this period, the token’s worth grew from a few dollars to six figures.
