A Bitcoin miner appears to have secured a major reward after earning a block incentive worth around US$266,000, or more than Rp4.4 billion, upon successfully mining block number 924,569 on the Bitcoin network on Friday (Nov 21, 2025).

According to data from CKPool, the solo miner—believed to be using a hobby-grade device with a speed of roughly 1.2 terahashes per second—managed to earn a total of 3.146 BTC. This amount includes the standard block reward of 3.125 BTC plus transaction fees generated from 1,351 transactions included in the block.

Such an achievement is extremely rare, considering the miner’s chances were only a fraction compared with the major players in the industry.

The Nearly Impossible Odds of a Solo Miner

The miner is estimated to have used a small device such as the Bitaxe Gamma, a compact mining machine for hobbyists priced at around US$100 or less. Statistically, the likelihood of such a low-powered device mining a block in a single day is only around 0.00068390%, or less than 1 in 100,000.

However, in this instance, luck was on their side, resulting in a reward worth hundreds of thousands of dollars.

Most large mining entities combine their computational power in mining pools to increase their chances of discovering blocks. In contrast, solo miners operate independently without joining others, resulting in significantly lower odds—often compared to winning a lottery.

Even so, each time a victory like this occurs, the Bitcoin community celebrates it as proof that the network continues to offer opportunities for smaller miners.

Throughout 2025, successful solo-mined blocks have become more frequent. Mempool data shows that at least 13 blocks have been mined solo this year—averaging slightly above one successful block per month. Still, the numbers affirm that such events remain exceptionally rare amid the dominance of major mining pools.

Beyond chasing rewards, solo miners are also considered to strengthen Bitcoin’s decentralization. As more diverse participants help secure the network, the community believes Bitcoin’s security structure will remain more resilient in the long run.
