Solo Miner Earns 3.125 BTC for Mining Bitcoin Block

A solo miner using CKpool mined block #912632 and earned 3.125 BTC ($338,000) plus 0.022 BTC in fees. A rare case of profitable solo Bitcoin mining in 2025.

Solo Mining Still Brings Surprises

In a rare event for the Bitcoin mining industry, CKpool administrator Con Kolivas announced that a solo miner successfully mined block #912632. The reward amounted to 3.125 BTC worth $338,000, along with an additional 0.022 BTC ($2,400) from transaction fees.

This was the 306th block mined through CKpool, a platform where miners work independently. Unlike traditional mining pools, CKpool does not redistribute rewards—only the miner who finds the block gets paid.

Mining Power and Rare Luck

According to Kolivas, the miner’s hash rate at the moment of success was 61 Ph/s, but at times it reached 240 Ph/s. This equals roughly 1,200 ASIC devices, each with 200 Th/s capacity.

CKpool only charges fees for network support and fast block inclusion. Success depends on network difficulty and mining hardware power. In theory, even weaker devices can mine a block, but the chances are extremely low.

Why This Matters for Miners

This case shows that solo Bitcoin mining is still possible, though highly unlikely without vast resources. With rising network difficulty, the probability of success decreases, but rare victories like this one keep the solo mining dream alive and inspire enthusiasts around the world.
