Top 5 Altcoins To Buy Today As Altcoin Season Heats Up (16 -17July 2025)

Altcoin season is potentially underway as Bitcoin dominance has decreased and Ethereum has shown strength. The total crypto market cap excluding Bitcoin has reached $1.34 trillion, signaling a rotation into altcoins. Five altcoins are highlighted as potential buys due to bullish signals and catalysts: Sui (SUI), Arbitrum (ARB), Avalanche (AVAX), Hedera (HBAR), and Chainlink (LINK). Sui's Total Value Locked hit a new high of $2.326 billion, boosted by a partnership with Google Cloud and institutional validators. Arbitrum's Timeboost system has generated over $2 million in fees, making it a self-sustaining ecosystem. Avalanche was chosen by FIFA to power the FIFA+ collectibles platform. Hedera saw increased institutional interest following its inclusion in Grayscale's Smart Contract Platform Fund. Chainlink's role has deepened through its involvement in tokenized funds and the launch of its Cross-Chain Interoperability Protocol.
