Introduction
Bitcoin has once again captured global attention, with media hype and even central banks weighing in on this digital phenomenon. Despite a recent 35% price drop, Bitcoin's value remains significantly higher than earlier this year, tempting many newcomers to try their hand at "mining." However, today's Bitcoin mining landscape has drastically changed—here's why amateur miners face steep losses and how the industry's hidden mechanisms work against individual participants.
Understanding Bitcoin and Mining Basics
What Is Bitcoin?
Bitcoin is a decentralized digital currency built on peer-to-peer (P2P) technology. Designed to be inflation-resistant, its supply is capped at 21 million coins, with transactions verified by a distributed network of computers.
Key attributes:
- Decentralized control: No central bank governs issuance.
- Dual role: Functions as both a currency and a speculative asset.
- Price volatility: Values fluctuate wildly (e.g., dropping from ¥7,050 to ¥4,521 in weeks), creating opportunities—and risks—for traders.
How Does Mining Work?
Mining involves using hardware (CPUs, GPUs, or specialized ASICs) to solve complex mathematical problems, generating new Bitcoins as rewards.
Critical shift:
- Early days: GPUs (especially AMD cards) were efficient for mining.
- Now: ASIC miners dominate, offering speeds hundreds of times faster than top-tier GPUs, rendering consumer hardware obsolete.
The Dark Side of Bitcoin Mining
1. The Illusion of "Easy Money"
- Misleading claims: Some miners boast earnings like "¥140,000 daily," but these figures ignore rising computational difficulty and hidden costs.
- Reality check: Today’s mining requires industrial-scale operations; individual miners face slim-to-negative margins.
2. The Scam Behind Mining Hardware Sales
- Pre-order traps: Manufacturers hype next-gen miners while using them to mine themselves. By delivery time, the hardware is outdated, and difficulty has surged.
- Example: Buyers of Avalon chip miners faced delays and reduced profits due to withheld shipments and escalating competition.
3. Centralization Threats
- Pool dominance: Two largest mining pools control >51% of Bitcoin’s hash rate, undermining decentralization.
- Market manipulation: "Whales" (large holders) manipulate prices, squeezing out small players.
4. Regulatory and Corporate Backlash
- Government bans: China, South Korea, and others restrict Bitcoin’s use as currency.
- Corporate bans: Apple, Baidu, and telecom giants block Bitcoin-related services.
Alternatives and Risks
Litecoin: A Bitcoin Alternative?
- GPU-minable: Unlike Bitcoin, Litecoin resists ASIC dominance—for now.
- Improved features: Faster transactions, but likely to face similar centralization issues long-term.
Why PC Gamers Should Avoid Mining
- GPU mining is dead: With ASICs achieving 1000x GPU speeds, even high-end rigs can’t compete.
- Energy costs: Electricity expenses often exceed earnings for amateur miners.
Conclusion: A Bubble Waiting to Burst
Bitcoin’s original vision as a decentralized currency has collapsed under speculation, centralization, and regulatory pressure. Today, it operates as a high-risk investment—akin to gambling.
Final warnings:
- Early adopters profited; latecomers risk heavy losses.
- Mining hardware sales often prey on uninformed buyers.
- The market resembles a "greater fool" scheme—profits depend on finding new buyers to offload risks onto.

FAQ
Q: Can I still mine Bitcoin with my gaming PC?
A: No. ASIC miners have made GPU mining unprofitable.
Q: Is Litecoin a better option?
A: Temporarily, but expect similar centralization issues as adoption grows.
Q: Why do governments oppose Bitcoin?
A: Concerns over financial stability, tax evasion, and illicit activities.
Q: Are mining hardware sellers trustworthy?
A: Many delay shipments or sell obsolete gear—research thoroughly before buying.
