Introduction

Cryptocurrency security is unforgiving - lost passwords mean lost funds forever, and compromised accounts result in irreversible theft. Unlike traditional banking, there's no customer service to reverse fraudulent transactions. This guide provides comprehensive security practices for protecting your digital assets.

Why Crypto Security Is Different

Irreversible Transactions

Key differences from traditional finance:

• No chargebacks or reversals
• No fraud protection
• No FDIC insurance
• No customer service recovery
• You are your own bank

Consequences:

• Lost password = lost funds permanently
• Stolen crypto = gone forever
• Wrong address = funds lost
• Compromised seed phrase = total loss

High-Value Targets

Why attackers target crypto:

• Instant, irreversible transfers
• Anonymous transactions
• High value concentration
• No recovery mechanisms
• Global accessibility

Common attacks:

• Phishing for seed phrases
• Exchange account takeovers
• SIM swapping for 2FA
• Malware (clipboard hijacking)
• Social engineering
• Physical threats
