Choosing a Bitcoin mining platform is like "opening a mystery box"—some strike gold, others lose everything. Here are 7 key indicators to avoid pitfalls.

1. Legality & Transparency: Verify "ID" Before Partnership
Legitimate platforms disclose licenses like banks, while fraudulent ones hide registration details.

• Action Steps:

• Check "About Us" on the website footer

• Verify licenses on regulators' portals (e.g., US NFA, UK FCA)

• Avoid platforms claiming "No KYC required"

2. Operational History: Avoid Being the First Tester
Scam platforms average 1.2 years lifespan, while veterans like AntPool thrive for 12 years.

• Key Data:

• 75% survival rate for platforms over 3 years

• 42% risk of new platforms collapsing within the first year

3. Fund Management: Cold Wallet Ratio is Critical
An exchange lost 120k BTC due to hot wallet hacks, whereas Gemini stores 98% assets offline.

• Metrics:

• Safe threshold: Cold wallet ratio >90%

• Bonus points for hardware wallet integration (e.g., Ledger/Trezor)

4. Profit Logic: Bitcoin Doesn’t Fall from the Sky
Platforms offering "3% daily ROI" (e.g., collapsed Maiduoduo) are Ponzi schemes. Real mining profits fluctuate with network hash rate.

Formula:
Your Profit = (Your Hashrate / Network Hashrate) * Block Reward - Electricity - Fees
Flee if "guaranteed returns" are promised!

5. Technical Security: Hackers Target Weak Links

• Must-Have Features:
  ✅ Two-Factor Authentication (2FA)
  ✅ SSL Encryption
  ✅ Regular Third-Party Audits

6. Community Reputation: The Crowd Sees Clearly
Red flags include delayed customer service, muted groups, and sudden high-yield products.

• Research Tools:

• Check Reddit/r/BitcoinMining complaints

• Use Whois for domain expiration checks

7. Exit Mechanism: Easy In, Hard Out?
Reliable platforms allow T+0 withdrawals (e.g., OKExPool), while risky ones impose "180-day lockups" or "10 BTC minimum withdrawal".

• Test Steps:

1. Deposit minimum amount (e.g., 0.001 BTC)

2. Withdraw within 24 hours

3. Verify speed and fees
