Disadvantages of Decentralized Exchanges
- High Fees: Ethereum network congestion inflates costs.
- Scam Risks: No vetting for fraudulent tokens.
- Limited Features: No fiat support or advanced charting tools.
When to Use CEX and DEX?
| Use Case | CEX | DEX |
|---------------------|-----------------------------------------|-----------------------------------------|

| Privacy | KYC required | Anonymous trading |
| Tokens | Established coins (BTC, ETH) | Low-cap "gems" |
CEX Best For: Beginners, fiat conversions, high liquidity trades.
DEX Best For: Privacy-focused traders, early-stage token investments.
