(Image credit: Shutterstock) A solo miner running just 6 terahashes per second of computing power has overcome odds of about 1 in 180 million to mine a full Bitcoin block via the CKpool pool. According to CoinDesk , the miner secured 3.146 BTC plus transaction fees — a payout worth around US$270,000 at current rates , despite commanding only about 0.0000007% of the network’s estimated 855.7 exahashes/sec of hash‑rate.
The figure was confirmed by CKpool creator Con Kolivas, who said that the miner only had “a one in 180 million chance” of solving a block on any given day. The miner employed an older‑generation ASIC capable of roughly 6 TH/s, submitted shares to CKpool’s solo‑mining infrastructure, and retained the full block reward minus CKpool’s 2% pool fee.
Congratulations to extremely lucky miner 3K99~Ct8M with only SIX TH for solving the 308th solo block at https://t.co/UWgBvLkDqc. A miner of this size has only a a in 180 million chance of solving a block each day! https://t.co/Jx3fTUlaIe pic.twitter.com/F5CKVrEfYt November 21, 2025
Headline‑grabbing payout aside, the miner’s win shows how rare solo mining has become for small operators. With network difficulty and aggregate hash‑power climbing steadily, the chance of a tiny miner solving a block without significant scale is vanishingly small. In practical terms, operating at 6 TH/s in a sea of hundreds of exahashes is akin to buying one lottery ticket in a contest where billions of tickets are already in play.
