Crypto Ch8: Risk & Survival
Chapter 8. Risk, scams, and survival
8.1 Why survival matters more than speed
Crypto contains many irreversible failure modes.
Examples include:
- Seed phrase compromise
- Malicious approvals
- Extreme leverage wipeout
- Exchange failure
- Protocol exploits
- Bridge failures
A major part of crypto risk is not “being wrong” but “being permanently out.”
8.2 Main classes of risk
- Market risk
- Custody risk
- Protocol risk
- Counterparty risk
- Operational risk
- Oracle risk
- Bridge risk
The value of this classification is practical: before taking any opportunity, you should know which family of risk you are actually taking.
8.3 Custody risk
If someone else controls the withdrawal path or the keys, your assets are subject to their policies, solvency, and integrity.
8.4 Protocol risk
Code can fail. Governance can fail. Upgrade authority can be dangerous. Mechanism design itself can be fragile.
8.5 Bridge risk
Bridges connect systems and therefore often create concentrated technical and trust assumptions.
8.6 Oracle risk
A protocol that relies on bad external data can fail even if its own code is otherwise sound.
8.7 Operational risk
Many catastrophic losses come from user actions:
- Sending to the wrong address or chain
- Signing a malicious transaction
- Entering a seed phrase into a fake website
- Running large balances through unsafe hot-wallet workflows
8.8 Common scam patterns
- Rug pulls
- Fake airdrops
- Fake wallets and browser extensions
- Fake support staff
- Pump-and-dump groups
- Urgency-driven phishing
8.9 A practical risk checklist
Before entering any position, protocol, or platform, ask:
- What exactly am I doing?
- Where is the yield coming from?
- What class of risk am I taking?
- What is the worst-case outcome?
- Through what path would that worst case happen?
- If it happens, how much do I lose?
- Is the position size appropriate for that risk?
Key takeaway
Risk management in crypto is not about never making mistakes. It is about ensuring that mistakes do not become terminal.
