I just came across a story about a solo miner who simply mined a Bitcoin block by himself. Cal Kolivas from CKPool mentioned that the guy received a reward of 3.13 BTC, plus an additional 0.004 BTC in fees. Block 913,593 with 593 transactions is quite an achievement. The equipment was running at 200 TH/s, and the probability of such an event happening with this power is roughly once every 100 years. Crazy odds, honestly. Interestingly, administrator Cal Kolivas noted that this is already the 307th block confirmed by solo miners through the platform. CKPool operates differently from regular pools. Here, mining power isn't shared; each miner mines independently, and the entire reward goes to whoever finds the block first. Since September, network competition has increased sharply, making such events even more rare. Cal Kolivas has previously talked about similar cases—another miner received 3.125 BTC. It’s probably like winning the lottery, but with computational power instead of a ticket.
