A group of miners questions the profitability of using 100 S19j Pro Bitcoin mining machines in June 2025. Recent discussions on forums reveal varying insights, with some claiming they earn significantly less compared to previous months. The sharp drop in profitability has raised concerns among those in the crypto community.
Mining operations have faced backlash amid recent changes in earning potential. Discussions have intensified on multiple platforms following the April 2024 halving event, which many believe affected earnings drastically. As one participant remarked,
"Before April 20, 2024, I got about BTC/day, why now I have about BTC/day?"
Key Insights from Mining Discussions
Here are the main points gathered from user comments:
Profitability Concerns
Several users report earnings around $25 per day, far less than anticipated.
One miner shared insights about electric costs affecting overall revenue, stating, "510 dollars but after electric around Kw/h. It’s like negative a month."
Calculation Challenges
A user clarified:
"(your_hashrate/network_hashrate)* = daily_BTC"
This formula points to the necessity of recalculating potential daily earnings regularly.
Criticism of Methodology
There are claims of unsustainable operational costs. A comment mentioned: "Nobody is running on 7-8 Kwh. That’s crazy."
Community Sentiment
The sentiment across forums has been mixed. While some remain hopeful about their setups, many voice frustration over decreasing returns.
Key Takeaways
△ Profit margins shrinking: Many miners report a loss of daily income per machine.
▽ Operational costs rising: Higher electricity costs impact net earnings.
※ Growing call for clarity: Users demand better explanations from manufacturers about performance.
As bitcoin miners adapt to fluctuating profitability, one question lingers: will the influx of advanced machines improve daily earnings, or are miners facing a tougher landscape ahead?
What Lies Ahead for Bitcoin Miners
There’s a strong chance that without adjustments to overhead costs, many bitcoin miners may find themselves re-evaluating their operations. As operational expenses rise, especially with fluctuating electricity prices, experts estimate around a 20% decline in profitability for most miners using older models like the S19j. Furthermore, advancements in mining technology could help newer machines improve efficiency, but these innovations often come at a steep price. It’s likely we’ll see a shift in focus towards newer, more energy-efficient machines, while older setups could face obsolescence in the coming months, reshaping the landscape of profitability in the mining sector.
Reflecting on Past Industries
This situation resembles the early days of the automobile industry when mass production met rising material costs. Much like miners grappling with earnings, early manufacturers had to adapt quickly to a changing marketplace; many went under, while others innovated with more sustainable practices. The parallels between these industries continue to unfold. Just as automakers learned to optimize production methods and pivot away from costly materials, today’s bitcoin miners might need to rethink their strategies. This metamorphosis could redefine the industry, with lessons from history reminding us that adaptation is crucial for survival.
