The essence of Bitcoin mining is: miners use hashrate to keep track of the network, and the system rewards them with BTC as an incentive mechanism.
Simply put, miners are like accountants distributed worldwide, automatically recording all transactions with mining machines (specialized computers). When a mining cycle is successfully completed, they receive a certain amount of BTC as a reward.
How Does Mining Work? Core Mechanism Breakdown
Bitcoin uses a mechanism called “Proof-of-Work”(Proof-of-Work, PoW). The process is as follows:
Step 1: Transaction Packaging — All transactions on the Bitcoin network are collected and packaged into a “block”
Step 2: Competitive Calculation — Miners worldwide compete to perform complex cryptographic computations to find a hash value that meets certain criteria. This process is similar to repeatedly trying password combinations until the correct one is found
Step 3: Verification and Broadcast — The miner who first finds the answer broadcasts the new block to the entire network, and other nodes verify it
Step 4: Reward Collection — Once most nodes confirm, the block is added to the blockchain, and the successful miner receives the reward
This process is extremely difficult, which is why it can ensure network security. Currently, the total network hashrate exceeds 580EH/s, making it nearly impossible for a single device to mine successfully.
Where Do Miners’ Profits Come From?
Bitcoin miners’ income consists of two parts:
Income Source
Block Reward
Transaction Fees
Meaning
BTC earned for successfully verifying a block
Fees paid by users when making transactions
Paying Party
Automatically generated by the Bitcoin system
Paid by transaction initiator
Amount Variation
Halves every 4 years: 50→25→12.5→6.25→3.125 BTC
Variable, depends on network congestion
Importance Change
Decreases year by year
Increases year by year
Early on, mining was highly profitable relying on block rewards, but as halving cycles progress, transaction fee income accounts for an increasing proportion. Especially after 2023, with increased on-chain activity, fee income has become a significant part of miners’ total revenue.
What Has Changed in the Mining Industry Since 2023?
Evolution of Mining Machines: From CPU to ASIC
2009-2012: CPU era, ordinary computers could mine
First half of 2013: GPU mining rose
Second half of 2013 to present: ASIC professional miners dominate, Avalon, AntMiner, etc., become mainstream
Currently, mainstream mining machines cost between $1,000 and $2,000, with newer models offering higher hashrate but at higher prices.
Evolution of Mining Modes
Mode
Period
Features
Solo Mining
2009-2013
Individuals or small organizations operate alone, rewards are exclusive
Mining Pool Collaboration
After 2013
Multiple miners join forces, rewards split according to hashrate
Cloud Mining
After 2015
Mining farms built in the cloud, users rent hashrate
Well-known pools include F2Pool, Poolin, BTC.com, AntPool, etc.
Industry Centralization Trend
The most obvious feature of mining in 2023 is increased monopoly by large capital. High costs of mining machines and huge electricity consumption mean only large-scale mining farms with economies of scale can be profitable. The survival space for individual miners has been greatly squeezed.
Impact of the 2024 Halving Event
In April 2024, Bitcoin will complete its fourth halving, reducing the block reward from 6.25 BTC to 3.125 BTC. This will have a significant impact on the entire mining ecosystem:
Short-term Impact
Miners’ income will be cut in half (if the price remains unchanged)
Miners with low efficiency or high electricity costs face exit, triggering a “wave of surrender”
Short-term network hashrate drops, but is later replenished by more efficient large-scale farms
Long-term Adaptation
Miners rely more on transaction fee income
Push for mining machine upgrades, phasing out old equipment
Mining activity shifts to regions with lower electricity costs
Can You Still “Mine” Bitcoin for Free?
The answer is: Basically impossible.
Comparison: Early vs. Now
Dimension
2009-2012
2023-2025
Mining Hardware
Personal computers
Professional ASIC devices
Cost
Several hundred USD
$1,000–20,000+ USD
Mode
Solo mining
Must join mining pools
Difficulty
Low, individual can mine
Extremely high, fierce competition
Expected Returns
High and stable
Low and unstable
Even if you buy mining machines and join pools, the BTC mined often cannot cover electricity, depreciation, and operational costs. According to statistics, by May 2025, the cost to mine one BTC is about $108,256, making it nearly impossible for individual miners to achieve this efficiency.
Do Individuals Still Have a Chance to Participate in 2023 Mining?
Three Traditional Paths for Mining
1. Self-purchase and operation of mining machines
Requires sufficient capital (starting from 100,000–500,000 RMB)
Needs access to cheap electricity regions
Requires professional maintenance skills
Suitable for: investors with capital and technical expertise
2. Purchase machines and entrust third-party hosting
Reduces operational complexity
But hosting fees are high, profits are shared
Must choose reputable hosting providers carefully
3. Rent hashrate
Platforms like NiceHash, Genesis Mining offer rental services, but yields are not ideal, often resulting in losses.
Key Points to Note
Legality check: Different regions have varying regulations on mining; confirm local policies
Identify scams: Be cautious of platforms promising high returns; choose well-known industry solutions
Electricity costs: Critical factor; profit is feasible only if electricity is below $0.05 per kWh
Complete List of Mining Costs
The cost to mine one Bitcoin includes:
Hardware investment: Cost of mining machines, largest component
Electricity costs: Daily consumption to run the machines, usually the second-largest expense after hardware
Cooling systems: Heat dissipation, air conditioning, liquid cooling, etc.
Infrastructure: Venue rental, network maintenance
Labor and operations: Monitoring, repairs, management costs
Mining pool fees: Usually 1-4% of profits
Simplified formula: Total Cost = Hardware + Electricity + Other Operating Expenses
Does Mining Revenue Really Make Money?
Profitability depends on:
Current BTC price
Network difficulty (higher hashrate means higher difficulty)
Personal hashrate
Local electricity costs
Using online calculators (like MacroMicro), you can estimate earnings by inputting parameters. But the key point is: Most individual miners have struggled to achieve positive returns after 2023.
Future Trends of Mining in 2023
Industry Landscape
Small miners gradually exit, with hashrate concentrated in large farms
Farms rely on economies of scale (low electricity costs, new models, automation) to compete
Industry automation and institutionalization continue to deepen
Possible New Opportunities
Green energy mining: Using wind, hydro, and waste energy
Hybrid farms: Combining AI computing power rental to improve equipment utilization
Multi-coin mining: Automatically switching to other coins when BTC difficulty is high
Conclusion
From 2023 to 2025, Bitcoin mining has evolved from a side hobby for individuals to an industry dominated by institutions. The era of “free mining” in the traditional sense has ended.
