Solo Miner Makes $330K by Renting Hash Power on CKpool

• Solo Bitcoin Miner Earns $330K Per Block
• Rented hash rate increases chances of mining block
• CKpool reaches 300 blocks mined solo

A solo Bitcoin miner has surprised the community by successfully mining block 899.826 and securing a total reward of approximately $330.000. The feat was accomplished using CKpool's solo mining software, according to project developer Con Kolivas.

In the transaction, the miner received 3,15 BTC, totaling $327.625 in subsidy and about $2.761 in transaction fees, as per data from the Mempool explorer. The beneficiary address, identified as bc1qa8r4up9nchkvdnhcf9feexv2jfantrk48ef374, was publicly congratulated by Kolivas on X (formerly Twitter).

Congratulations to miner bc1qa8r4up9nchkvdnhcf9feexv2jfantrk48ef374 who recently ramped up hashrate for solving the 300th block solved at https://t.co/UWgBvLkDqc ! https://t.co/36sDX051fH pic.twitter.com/NY2KJUxlQQ

Data reveals that the account maintained a weekly hash rate of 6,11 PH/s, but temporarily increased this computational power to 261 PH/s. This indicates the likely use of hash rate rental services to significantly increase the chances of successful block mining.

“This hash rate was almost certainly a rent based on there being only one worker, even though the account had been mining for some time at a much lower hash rate,” Kolivas explained.

The probability of a solo miner succeeding under these conditions is extremely low. With the Bitcoin network’s global hash rate at 796 EH/s at the time of the event, the estimated chance of success was just 0,03%, which equates to one in 3.050 attempts.

Despite the improbability, this was the 300th block mined by users of CKpool, a platform aimed at solo mining enthusiasts. Similar cases, although rare, have occurred before. In April 2024, a solo miner won $218.544 by beating odds of 1 in 5.000. In another episode, the odds were 1 in 1,3 million, with a reward of $260.000.

Using solo mining, especially with rented hash rate, remains a risky bet, but in cases like this, it can result in significant profits for well-positioned miners.
