Cryptocurrency mining has often been dubbed the new "gold rush" — a process that creates and processes digital currencies. Unlike traditional mining, it doesn't involve handheld tools but requires computer processors to solve complex mathematical problems.
How Does Cryptocurrency Mining Work?
Cryptocurrency mining is the process of adding new coins to circulation. Miners use powerful computer hardware to solve intricate mathematical problems. The first miner to solve the problem receives cryptocurrency rewards, stored in their digital wallet. While profitable, mining consumes significant energy.
Blockchain Technology
Cryptocurrencies operate without central banks, relying instead on blockchain technology. A blockchain is a database that groups information into blocks. Once a block is filled, it closes and links to the previous block, forming a chain. Due to its linear design, miners can only add information to the latest block, not edit or delete existing data.
Proof-of-Work (PoW) Mechanism
Cryptocurrencies like Bitcoin and Ethereum use PoW algorithms to confirm transactions and track new coin creation. Miners compete to create blocks containing verified data. Successful miners earn cryptocurrency rewards.
Personal Mining vs. Cloud Mining
Miners can choose between two approaches:
- Personal Mining: Requires specialized hardware (e.g., high-end GPUs or ASIC chips for Bitcoin).
- Cloud Mining: Easier entry; rent mining capacity from cloud providers, ranging from small services to entire networks.
Mining Pools
Due to the high computational and energy demands, individual miners with limited resources often join mining pools — groups that combine computing power to solve problems and share rewards.
Energy Consumption
Cryptocurrency mining is energy-intensive. Cambridge University’s Centre for Alternative Finance estimates Bitcoin mining consumes 0.55% of global electricity — comparable to Malaysia or Sweden’s annual usage.
Is Cryptocurrency Mining Legal?
Legality varies by country. Some nations permit virtual currency use, while others ban it entirely. Always verify local regulations before starting.

Cryptocurrency Mining Malware Threats
Cybercriminals target miners with custom malware that hijacks computer resources, crippling performance and accelerating hardware wear. Common infection methods include:
- Malicious email attachments
- Bundled software downloads
- Potentially Unwanted Applications (PUAs)
Example Attacks:
- Fileless mining malware hidden in legitimate apps
- Monero mining viruses exploiting zero-day vulnerabilities
Can You Profit from Mining? How to Start
Mining can be lucrative but requires careful planning:
Cost Factors:
- Electricity expenses
- Equipment acquisition/pricing
Risks:
- Market volatility
- Scams, theft, and hacking
Profitability depends on cryptocurrency value exceeding operational costs. Lower expenses mean higher income. However, increased mining difficulty or price drops can reduce earnings.
FAQ
Q: Is home mining still viable in 2025?
A: Yes, but profitability depends on hardware efficiency and electricity costs. Cloud mining may be more accessible.
Q: How do I choose a mining pool?
A: Look for low fees, transparent payout structures, and reliable uptime.
Q: What’s the most energy-efficient cryptocurrency?
A: Coins using Proof-of-Stake (PoS) algorithms (e.g., Ethereum 2.0) consume less energy than PoW-based currencies.
