## Introduction
In the volatile world of cryptocurrencies, stablecoins like **USDT (Tether)** and **USDC (USD Coin)** provide crucial price stability by pegging their value to the US dollar. With over $110 billion combined market cap, these giants dominate the stablecoin landscape. But how do they differ? This comprehensive guide examines their security, transparency, use cases, and risks to help you decide which suits your crypto strategy.
## What Are Stablecoins?
Stablecoins are blockchain-based tokens designed to maintain a consistent value, typically 1:1 with fiat currencies like the USD. They enable:
– Low-volatility crypto trading
– Efficient cross-border payments
– DeFi lending/borrowing
– Hedging against market swings
Unlike Bitcoin or Ethereum, stablecoins avoid extreme price fluctuations while leveraging blockchain’s speed and security.
