As the first cryptocurrency, Bitcoin remains the market leader, with high liquidity and widespread recognition. Its scarcity (total supply of 21 million) and status as 'digital gold' make it optimistic for the long term.

2. **Ethereum (ETH)**

Ethereum is the leading platform for smart contracts and decentralized applications (DApps). With the advancement of the Ethereum 2.0 upgrade, its performance and scalability are expected to improve further, potentially driving its price up.

3. **BNB (Binance Coin)**

BNB is the native token of the Binance exchange, with various uses such as paying trading fees and participating in Launchpad projects. The ongoing expansion of the Binance ecosystem may bring appreciation potential for BNB.

4. **Cardano (ADA)**
