Bitcoin mining has become an incredibly competitive and specialized field. Here’s a breakdown of whether it’s possible to mine 0.1 BTC with the equipment you described and how long it would take:
Bitcoin Mining: Is It Possible with 2 PCs, 10 Mobiles, and How Long Will It Take to Mine 0.1 BTC?
The Short Answer: Highly Unlikely and Not Recommended for Profitability
While theoretically, any device with processing power can participate in Bitcoin mining, the reality of the current Bitcoin network makes it practically impossible to mine a significant amount like 0.1 BTC using only 2 PCs/laptops and 10 mobile phones.
Here’s why:
- The Evolution of Bitcoin Mining Hardware:
- ASICs Dominate: Bitcoin mining is dominated by Application-Specific Integrated Circuits (ASICs). These are specialized machines designed solely for Bitcoin mining and are incredibly efficient at solving the cryptographic puzzles required. They offer hash rates (the speed at which calculations are performed) that are orders of magnitude higher than general-purpose computers or mobile phones.
- CPU/GPU Mining is Obsolete for BTC: In the early days of Bitcoin, it was possible to mine with CPUs (Central Processing Units) and then GPUs (Graphics Processing Units) found in regular PCs. However, as the network grew and more powerful ASICs were developed, the “difficulty” of mining Bitcoin increased dramatically.
- Mobile Phone Mining: Not for Bitcoin: Mobile phones have very limited processing power compared to even a basic PC. While some apps claim to “mine crypto” on mobile, they often engage in cloud mining (where you pay for hash rate on remote servers), mine altcoins (different cryptocurrencies) that are less computationally intensive, or are simply not legitimate. Directly mining Bitcoin on a mobile phone is not feasible and would likely damage the device due to overheating and excessive resource usage.
- Bitcoin Network Difficulty and Hash Rate:
- High Difficulty: The Bitcoin network automatically adjusts its mining difficulty every 2,016 blocks (roughly every two weeks) to ensure that a new block is found, on average, every 10 minutes. As more powerful miners join the network, the difficulty increases, requiring even more computational power to earn rewards.
- Massive Network Hash Rate: The global Bitcoin network hash rate is enormous, measured in exahashes per second (EH/s). Your 2 PCs and 10 mobiles would contribute a negligible fraction of this, essentially a drop in the ocean.
- Power Consumption vs. Rewards:
- Electricity Costs: Even if your devices could mine, the electricity consumed by running them 24/7 would far outweigh any potential Bitcoin earnings. Regular PCs and laptops are not optimized for continuous, high-load computational tasks like mining, and they would consume significant power without yielding much.
- Diminishing Returns: The current block reward for Bitcoin (as of the April 2024 halving) is 3.125 BTC per block. This reward is split among all miners in a pool (if you join one) proportional to their contributed hash rate. With minimal hash rate from your setup, your share of any block reward would be infinitesimally small.
How Much Time It Would Take (Hypothetically, and Extremely Long):
Given the current Bitcoin network difficulty and the extremely low hash rate of 2 PCs and 10 mobile phones (even high-end ones), it would realistically take many, many years, likely decades or even centuries, to accumulate 0.1 BTC. You would almost certainly spend far more on electricity than the value of the Bitcoin you might hypothetically mine.
Conclusion:
Attempting to mine 0.1 BTC with 2 PCs/laptops and 10 mobile phones is not a viable or profitable strategy in 2025. Your resources would be better spent: - Purchasing Bitcoin directly: This is the most straightforward and efficient way to acquire BTC if you believe in its value.
- Exploring other cryptocurrencies: Some less-known altcoins are designed to be mineable with CPUs or GPUs, but even these often require dedicated hardware to be truly profitable.
- Learning about cloud mining services: While these come with their own risks (scams, high fees), they allow you to rent hash rate from large mining farms, potentially offering a more realistic path to earning some crypto without owning expensive hardware.
For serious Bitcoin mining, the only practical approach is to invest in dedicated ASIC miners and join a reputable mining pool.
