3. **Stablecoins (e.g., USDC, USDT):** Pegged to the US dollar to minimize volatility but require careful consideration of regulatory compliance.
4. **Binance Coin (BNB):** Used within the Binance ecosystem for various purposes, though it faces some regulatory scrutiny.
5. **Cardano (ADA) and Solana (SOL):** Known for advanced technology and fast transactions, but carry higher risk compared to Bitcoin or Ethereum.
