The summer of 2025 has brought renewed optimism to the crypto space. Following Bitcoin’s halving, the market has strengthened, and BTC has surged past $115,000. Naturally, interest in mining is picking up again. But is it actually profitable today? And is now the right time to invest in mining hardware?
Start Smart : Don’t Rush into Buying ASICs
In a post-halving market, caution and analysis are key. Instead of jumping into equipment purchases, take the time to do your homework. Speak with experienced miners, compare the performance of different models, evaluate hosting options, and most importantly, calculate your payback period.
When estimating profitability, it’s best to prepare for multiple scenarios:
- Baseline: Profitability remains stable
- Bearish: Revenue drops by 10% per month
- Bullish: Revenue increases by 2–3% per month
To make accurate forecasts, tools like ViaBTC’s Revenue Ranking and Mining Calculator can help. Input your miner model and electricity rate to get a clear picture of your potential earnings.
The Market in 2025: A Return to Bitcoin
Following last year’s altcoin boom, with notable projects such as Kaspa and Alephium, the mining spotlight has shifted back to Bitcoin and the SHA-256 algorithm. This segment now offers the best balance between risk and return, especially for miners seeking a stable, long-term strategy.
Top Mining Machines in 2025:
- Antminer S21+ – Industry leader in energy efficiency and ROI
- WhatsMiner M60 / M61 – Reliable and high-performance workhorses
- Avalon Q Series – Quiet and compact, ideal for home mining
Hardware prices have remained stable since the halving, while efficiency has improved. The S21+ stands out, as older machines went offline and network difficulty adjusted-creating stronger profitability potential for newer, high-efficiency models.
That said, electricity costs remain a critical factor. If your rate exceeds 8 RUB/kWh, your profits may be quickly eroded.
Why SHA-256 Remains the Smart Choice
Bitcoin mining offers unmatched stability. The algorithm has remained unchanged for over a decade, ASICs last for years, and institutional investment continues to grow.
Compare that to the altcoin market: Kaspa’s hashrate is dropping, older miners (KS1–KS3) are being retired, and even the newer KS5M/KS5L models are struggling to generate worthwhile returns under current hosting costs. The same applies to many altcoins: unpredictable rewards, highly volatile revenues, and extended payback periods.
For miners focused on risk management and sustainability, SHA-256 remains the gold standard.
Altcoin Mining: Scrypt Still Has a Niche
While SHA-256 is the top choice for most, Scrypt-based mining (e.g., LTC/DOGE) continues to show strong post-electricity returns. However, this sector requires more patience, especially during market downturns.
Choosing the Right Pool Matters
Choosing the right pool is just as important as choosing the right machine. For SHA-256 miners, ViaBTC is a top-tier choice:
- Over 14% of global BTC hashrate
- Top 3 Bitcoin mining pool worldwide
- Built-in analytics tools and full ecosystem: CoinEx Wallet, CoinEx Exchange, and ViaBTC Pool
With integrated tools for earnings tracking, payout flexibility, and network insights, it’s built to support miners aiming for consistent, optimized performance.
Final Thoughts
In today’s market, Bitcoin mining via SHA-256 remains the most balanced and future-proof option. With stable algorithms, robust institutional backing, and proven hardware, it’s a strategy built for long-term success.
For those exploring altcoins, Scrypt devices continue to perform well, particularly for miners who are patient and electricity-savvy.
Whichever path you choose, the keys to success remain the same: invest in energy-efficient hardware, calculate your ROI carefully, and work with trusted pools like ViaBTC, a name backed by years of proven performance.
