A solo miner found a Bitcoin block spending just $75 on rented computing power, pocketing over 3.125 BTC.
A solo miner earned a reward of over 3.125 BTC, equivalent to approximately $200,000, after finding block 938,092 in the morning of Tuesday, February 24. To do so, they spent just 119,000 satoshis (approximately $75) renting computing power through Braiins‘ hash power marketplace, which allows users to lease mining capacity directly from the company without having to install or manage any physical hardware.
The miner rented the minimum amount available on the platform: 1 Petahash per second (PH/s). Based on the current Bitcoin network hash rate, this level of computing power would statistically yield a successful block find approximately once every 1.1 million blocks — or roughly every 21 years of mining — according to estimates from SoloChance.com.
Solo mining is widely considered by experts to be the equivalent of “playing the lottery.” The vast majority of Bitcoin blocks are found by large mining pools, which concentrate enormous amounts of computational power to solve the cryptographic puzzles that underpin Bitcoin’s public ledger and network. Nevertheless, several similar cases have been reported in recent months: in January, two solo miners each earned rewards exceeding 3.125 BTC, worth approximately $300,000 at the time of discovery. In December, another miner beat the odds to claim a reward worth over $282,000 at Bitcoin’s price at the time.
These events are unfolding against the backdrop of an increasingly powerful network. The overall hash rate currently exceeds a daily average of 1.1 ZH/s, according to data from Bitinfo. During the same period last year, the network’s total computational power stood at around 730 EH/s — approximately 61% of its current capacity.
