USDT Tether is a stablecoin issued by Tether, ranking as the fourth-largest cryptocurrency by market capitalization with approximately $41 billion in circulation. Each USDT is pegged 1:1 to the US dollar, allowing users to exchange USD via SWIFT transfers or through cryptocurrency exchanges.
Why USDT Matters in Crypto Investing
USDT serves as a critical bridge in the crypto ecosystem. Due to regulatory restrictions, not all cryptocurrencies can be purchased directly with fiat currencies. Here’s why USDT is indispensable:
- Wide Acceptance: USDT supports over 100 trading pairs on exchanges like Binance.
- Stability: Acts as a safe haven during market volatility, allowing investors to park funds without converting back to fiat.
When Should You Use USDT Tether?
- Purchasing Unlisted Cryptocurrencies: Buy coins not available on local exchanges (e.g., MCO for Crypto Visa Cards).
- Asset Transfer: Move funds between international exchanges efficiently.
Types of USDT and How to Buy
USDT exists on multiple blockchains, each with unique features:
| Type | Blockchain Used | Transfer Speed | Common Use Cases |
|---|---|---|---|
| Omni | Bitcoin | Slow | Legacy support |
| ERC20 | Ethereum | Fast | Low-fee transfers |
| TRC | Tron | Instant | Zero-cost transfers |
