Banking analogy:

Traditional banks: Centralized ledger → Charge fees.
Bitcoin network: Miners compete to validate transactions → Earn Bitcoin rewards.

Why Proof-of-Work (PoW) is core:

Trust via math & energy:
- Hash computations consume real energy (~10²² attempts per transaction), converting physical energy expenditure into immutable trust.
- Example: Altering a single Bitcoin block requires redoing the network’s total hash rate (~500 EH/s as of 2025). Attacking for 1 hour would consume over 130,000 MWh (more than Sweden’s daily usage)
Decentralized equilibrium:
- Block time self-adjusts (e.g., Bitcoin’s 10-minute blocks). Miner profits depend on hardware efficiency, electricity costs, and coin prices, creating a global, competitive ecosystem

Revenue sources:

Block rewards:
- Miners earn newly minted coins (e.g., 6.25 BTC per block as of 2025, halving every 4 years)
- Transaction fees will dominate as block rewards diminish
Energy arbitrage & optimization:
- Off-peak mining (e.g., 22:00–8:00 reduces electricity costs by 30%)
- Heat recycling: Icelandic farms save $3M/year using geothermal heat

Method	Startup Cost	Risk	Best For	Platform Recommendations
ASIC Rigs	¥20,000+	Medium	Long-term investors	Antminer S19 Pro (subsidies available)
Cloud Mining	¥500+	Low	Beginners/short-term	[Starter packs] (with $10 trial)
GPU Mining	¥10,000+	High	Tech enthusiasts	(Caution: Refurbished GPU scams)
Pooled Mining	¥0	Very High	Not recommended	❗ Avoid "guaranteed returns" scams
Mobile Mining	¥0	Scams	None	❌ 100% fraudulent

Choose coin & pool:
- Bitcoin vs. Ethereum Classic vs. altcoins (https://www.coingecko.com).
- Recommended pool: F2Pool (low fees, Chinese support)
Setup hardware/cloud:
- ASIC rig wiring guides or cloud mining one-click purchases.
- ⚠️ Avoid "zero-configuration" rig scams
Monitor & withdraw:
- Use real-time dashboards to track hash rate, electricity costs, and profits.
Security setup:
- PIN: 8+ characters (mix letters, numbers, symbols). Avoid birthdays.
- Randomized keypad layouts to prevent tracking
Seed phrase backup:
- Write 24-word BIP39 phrases on fire/waterproof media (e.g., titanium). Never digitize or share
Withdraw to exchange/cold wallet:
- Tools: F2Pool https://www.f2pool.com/calculator(auto-updates prices & difficulty)

Trap 1: Electricity costs devour profits

Formula: Daily net profit = Mining income - (Rig power × Electricity rate × 24h)
Case: A user lost ¥8,000/month ignoring electricity costs.
Solution: Use calculators with global rate data (300+ cities)

Trap 2: Refurbished rig scams

Detection:
- Check solder points, firmware logs, and noise levels
- Compare components:

Component	Genuine Rigs (e.g., Antminer S19 Pro)	Refurbished Scams
Motherboard	Clean PCB, no oxidation (e.g., TSMC 5nm chips)	Rough soldering, rewired traces
Power Supply	≥94% efficiency (e.g., Bitmain APW12)	Swapped capacitors, unstable

Trap 3: Chasing "get-rich-quick" coins
