Introduction
Cryptocurrency exchanges have revolutionized digital asset trading, offering decentralized features and diverse functionalities. But how safe is your money on these platforms? Let's explore the security track records of major exchanges through their rankings—both red and blacklists.
Blacklisted Exchanges: Major Security Failures
1. Mt. Gox (2014)
- Incident: Hackers stole 850,000 BTC (worth ~$500B today).
- Lesson: Centralized single-key storage is high-risk; user funds depend entirely on platform security.
2. Coincheck (2018)
- Attack: 550M NEM tokens ($550M) stolen.
- Flaw: No cold wallet support + lax hot wallet key management.
3. Bitfinex (2016 & 2022)
- Breaches: 120K BTC ($72M) stolen in 2016; $200M lost in 2022 due to chain bridge exploits.
- Controversy: Mingled user/platform funds; questionable token-based compensations (e.g., LEO).
4. Smaller Exchanges (2023 Case)
- Risk: Insider collusion, fake withdrawal approvals.
- Warning: Lack of audits/transparency enables self-orchestrated theft.
