A solo Bitcoin miner overcame staggering odds to claim a $349,000 jackpot. Competing against major institutions typically demands extreme precision and, some argue, a fair amount of luck, especially when the odds of success are just 0.004 percent. Meanwhile, the broader crypto market is showing signs of an uptrend, spurred by Trump’s Big Beautiful Bill and other key developments.
Solo Bitcoin Miner Mines Block 903883 and Earns $349,000
An anonymous miner successfully mined block number 903883, earning a reward of 3.173 BTC. At the current Bitcoin price of $108,400, that translates to a payout of $349,028.
According to the Bitcoin Historian, this is a rare achievement, as most blocks are mined by large corporations with significant computational resources. Remarkably, the solo miner achieved this feat using just 2.3 petahashes per second of hash power through the CKpool solo mining pool.
It was highlighted that a miner with this level of power has only a 1 in 2,800 chance of solving a block alone. That equates to a 0.004 percent probability or roughly once every eight years.
To put this in perspective, mining a block typically requires around 166,000 terahashes per second, equivalent to operating 500 Antminer S21 Hydro units. Such an operation would cost millions of dollars upfront, not to mention the ongoing electricity expenses and logistical challenges.
Other Notable Solo Miner Wins
Despite the slim odds, solo miners have occasionally struck gold. In June 2025, one mined block 899826 and earned $330,000. Earlier, in February 2025, another solo miner earned nearly $300,000 by mining block 883181.
In a separate milestone, individual trader JohnGalt turned a $500 investment in a Bitcoin Gold bar purchased in 2012 into $10 million after redeeming it this year. Over that time, Bitcoin’s value surged from just a few dollars to over six figures.
