Pros of Using USDT
| Advantage | Description |
|---|---|
| Low volatility | Ideal for hedging against crypto market fluctuations. |
| High liquidity | Dominates trading pairs; easy to buy/sell globally. |
| Payment utility | Accepted by merchants and DeFi platforms; faster than traditional banking. |
Risks and Challenges
- Counterparty risk: Reliance on Tether Limited’s transparency in USD reserves.
- Regulatory scrutiny: Past controversies over reserve audits; Japan classifies USDT as "digital money-like stablecoin" under strict electronic payment laws.
How to Use USDT in Japan
Japan’s 2022 Payment Services Act divides stablecoins into two categories:
- Algorithmic stablecoins (e.g., DAI).
- Asset-backed stablecoins (e.g., USDT).
Since USDT isn’t traded on licensed Japanese exchanges, users can:
- Swap via private wallets (MetaMask, Trust Wallet).
- Access DeFi platforms supporting USDT pairs.
⚠️ Note: Verify swap compatibility—some tokens lack trading pairs.
