Remarkable Solo Mining Success
In a remarkable display of luck, a cryptocurrency miner turned a modest $75 investment in mining power into a substantial reward by discovering a rare solo block, yielding over 3.1 BTC, valued at approximately $200,000, early Tuesday morning. This individual utilized Braiins, a platform that enables users to lease Bitcoin mining capacity without the need for personal hardware installation or operation, to acquire the minimum rental of 1 Petahash/s (PH).
Challenges of Solo Mining
The odds of success at this level of mining power are daunting, with estimates from SoloChance.com suggesting that finding a block would typically occur only every 1.1 million blocks, equating to an arduous 21 years of mining. Solo mining rewards are particularly rare, given that most Bitcoin network rewards are captured by large mining pools that deploy extensive computational resources to address the cryptographic challenges integral to Bitcoin’s operational framework.
Experts often liken the chance of success in solo mining to a lottery, yet recent months have produced several unexpected winners.
Notably, two solo miners in January managed to secure rewards exceeding 3.1 BTC, valued at around $300,000 during that time, while another miner in December claimed a prize of over $282,000.
Increasing Network Hash Rate
This sporadic success is highlighted against the backdrop of a steadily increasing network hash rate, which has surpassed 1.1 Zhash/s on average daily, according to statistics from Bitinfo. Just a year ago, the total hash power of the network was significantly lower at around 730 Ehash/s, marking a 61% increase in computational capacity.
Shifts in Mining Focus
The surge in mining power could be influenced by a shift in the geography of miners, with a notable decrease in North American mining pool contributions as of 2025. Many miners, previously focused on Bitcoin, are pivoting their efforts toward meeting the burgeoning demands of AI computational power. For example, companies such as Bitfarms are phasing out their Bitcoin mining activities, while others like Riot Platforms are being encouraged by shareholders to explore opportunities within the AI sector.
A spokesperson from Braiins was not available for comment at the time of this report.
