Bitcoin miner mined 3.3 BTC alone! Has the "Lotto Mining Machine" had 4 miracles since July?

According to data from mempool, an independent miner through the Solo CKPool mining pool mined the Bit Block 867118 on October 24 at 17:18, earning 3.329 BTC (block reward + fees), worth approximately $222,000. It is worth noting that this is the fourth time an independent miner has mined a block reward since July (the first time, second time, third time), earning a substantial return from the Bit network. The first occurrence was on July 24 this year, when Altair Technology, a lottery mining machine manufacturer, claimed that an independent miner using their Bitaxe series model, through Solo CKPool, mined Bit worth about $210,000 at the time, with a return on investment much higher than the machine's price of $135 to $265. According to the official website, Solo CKPool uses a "solo mining" model, unlike traditional mining pools that concentrate computing power and distribute rewards proportionally. In Solo CKPool, each participant mines independently, and if a block is mined, the miner can obtain the entire block reward without sharing with other miners.

How low are the odds of winning?

The current network hash rate of Bit is 677.32 EH/s, but the CKPool hash rate is only 332 PH/s, accounting for only 0.049% of the entire Bit network hash rate. Furthermore, the pool may consist of hundreds of thousands to millions of mining machines, so the probability of a single mining machine successfully mining a block is extremely low. The miner who mined Bit Block 867118 on the 24th was extremely lucky. It is unclear what model and hash rate the miner used, but if the miner used an Antminer S19 XP with a hash rate of 140 TH/s, the network hash rate would be 4,838,000 times that of the miner's machine, meaning the machine would only have a 0.0000206% chance of successfully mining a block every 10 minutes (every block). If the miner used a Bitaxe lottery mining machine with a hash rate of only 500 Gh/s, the odds of winning would be even lower at 0.0000000738%, which is even more difficult than winning the lottery, where the odds of winning the grand prize are about 1 in 1.398 million, or 0.00000715%. While the "luck-based" solo mining model has seen an increase in winning frequency recently, for the average person interested in Bit mining, joining a traditional mining pool is generally more prudent, as it combines computing power with other miners to steadily earn a portion of the rewards.
