The cryptocurrency mining industry is experiencing unprecedented demand, driven by soaring Bitcoin and Ethereum prices. From sold-out mining rigs to repurposed gaming laptops, miners are scrambling to secure hardware—reshaping supply chains and fueling a global chip shortage.
Surging Demand for Mining Hardware
The Miner's Gold Rush
- Case Study 1: Miner "Li Wen" purchased 10 used M20S rigs for ¥70,000 in June 2020. These machines now yield over ¥300,000 annually in Bitcoin (1 BTC/year at current prices), while the hardware itself appreciated 200–300%.
- Case Study 2: Early adopter "Peter" invested ¥2M in 200 M20S rigs in 2019, generating 50+ BTC (worth ~¥16M). After deducting ¥150,000/month electricity costs, his net profit exceeds ¥10M.

Industry-Wide Shortages
| Hardware Type | Price Increase (2020–2021) | Lead Time |
|---|---|---|
| Antminer S19 95T | 150% (¥20K → ¥50K) | 8+ months |
| NVIDIA RTX 3060 GPU | 120% | Out of stock |
Manufacturers like Bitmain and Canaan report:
- Complete sell-out of inventory
- Pre-orders backlogged through Q3 2021
- Secondary market prices at 2–3x MSRP
Ethereum's GPU Crisis
The Graphics Card Gold Rush
- Miners are dismantling gaming laptops for GPUs, with some factories purchasing 10,000+ units to repurpose into mining rigs.
- NVIDIA implemented hash rate limits on RTX 3060 cards to prioritize gamers, while launching dedicated CMP mining chips.
Key Mining Hardware Alternatives
- ASIC Miners (Bitcoin-dedicated)
- GPU Rigs (Ethereum-compatible)
- FPGA Devices (Flexible but complex)

Understanding Crypto Mining Fundamentals
The Computing Power Race
- Bitcoin: Network hash rate grew 35.91% in 2020 (112.93 → 153.48 EH/s)
- Ethereum: Hash rate surged 98.78% (141.55 → 281.37 TH/s)
Mining Pool Dominance
| Cryptocurrency | Top 3 Pools | Market Share |
|---|---|---|
| Bitcoin | F2Pool, Poolin, BTC.com | 55.61% |
| Ethereum | SparkPool, Ethermine, F2Pool | 75.51% |
Mining vs. Trading: Risk Profiles
| Factor | Mining | Trading |
|---|---|---|
| ROI Timeline | 8–12 months (current) | Immediate |
| Volatility Risk | Lower (hardware hedge) | Extreme |
| Technical Skill | Medium (hardware setup) | High (market analysis) |
| Capital Outlay | High (equipment costs) | Flexible |
The DeFi Disruption
Decentralized Finance (DeFi) introduces "liquidity mining":
- Requires cryptocurrency deposits instead of hardware
- Total Value Locked (TVL) grew from $14B to $55B (Oct 2020–Mar 2021)
- Complements traditional mining by broadening crypto adoption
FAQ: Crypto Mining Essentials
Q: How long does a mining rig typically last?
A: Most ASIC miners remain profitable for 3–4 years before becoming obsolete.
Q: Can I mine Ethereum with a regular PC?
A: While possible, standalone GPUs or dedicated rigs yield better returns due to higher hash rates.
Q: What happens when all Bitcoin is mined?
A: Miners will transition to earning transaction fees (estimated post-2140).
Q: How does China's mining crackdown affect global markets?
A: It accelerated migration to North America and Central Asia, redistributing hash power globally.
Q: Is cloud mining a viable alternative?
A: Generally less profitable than owning hardware due to service fees and limited transparency.
Q: What's the environmental impact of crypto mining?
A: Many operations now use renewable energy, with some networks transitioning to less energy-intensive consensus mechanisms.
