## Introduction: Why USDT Security Can’t Be Ignored
As the world’s largest stablecoin with over $110 billion in circulation, Tether (USDT) has become foundational to crypto trading and DeFi. But its popularity makes it a prime target for hackers. This comprehensive guide reveals actionable strategies to keep your USDT secure against evolving threats – because in crypto, security isn’t optional; it’s survival.
## What Makes USDT Vulnerable? Key Threat Vectors
