The likelihood of such an event for a miner with similar capabilities is estimated to be approximately one in 100,000 per day, or once every 300 years, according to the developer.
According to blockchain analyst Mempool, the miner received a total of 3.128 BTC for mining block number 944,306. The reward consisted of a block subsidy of 3.125 BTC and transaction fees amounting to 0.003 BTC. The miner utilized CKpool’s software for solo mining.
A hash rate of 70 TH/s is comparable to that of a single Bitmain Antminer S17+ from 2019. Mempool reports that the fortunate miner’s hash rate represents about 0.0000069% of the total Bitcoin network hash rate.
Last week, another miner using CKpool in solo mining mode earned approximately $210,000 for mining block number 943,411. This ended a 33-day stretch without successful finds in the CKpool. At that time, the probability of finding a block for a miner was about one in 28,000 per day.
In September, a solo miner received a reward of $350,000 for a block, which is believed to occur once every 100 years. In December, another miner earned $285,000, with a similar chance occurring once every 82 years.
Previously, CoinShares analysts reported that the cost of mining 1 BTC for individual market participants exceeded $100,000. They estimate that the share of revenue from mining for large data centers (DCs) could drop from 85% to less than 20% by the end of the year.
