The 5 Best Cryptocurrency Investments Aside from Bitcoin for the Remainder of 2025

While Bitcoin continues to dominate headlines and portfolios with impressive institutional adoption, investors are shifting their focus to promising altcoins that may provide significant returns over time. If you're looking to diversify your cryptocurrency portfolio, here are some of the best altcoins to consider for the remainder of the year.

Ethereum (ETH) Ethereum remains the second largest cryptocurrency by market capitalization. While the rate of ETH holdings decreased earlier this year, it has recovered, signaling renewed interest. The continuous upgrades of the network and its dominance in DeFi, NFT, and decentralized applications (dApp) make it an attractive alternative. With the potential for Layer 2 scaling solutions, Ethereum may see increased interest from institutions. Solana (SOL) Although the investment portfolio has recently decreased from 2.72% in November 2024 to 1.76% in May 2025, Solana remains an attractive long-term investment. Solana's ability to handle high-volume applications while keeping costs low continues to attract developers to build DeFi projects and NFT platforms. Although some institutional capital has shifted from SOL to XRP, this decline may present a buying opportunity for long-term investors looking for better entry points. Ripple Ripple is attracting a lot of attention this year. The percentage of XRP held in portfolios has doubled from 1.29% in November 2024 to 2.42% in May, as investors believe that an exchange-traded fund (ETF) for XRP may soon be approved, which could drive the price up. XRP is also attracting attention for its fast and low-cost cross-border payment capabilities, making it a serious candidate for real-world financial use cases, especially in global remittances. Chainlink (LINK) Chainlink continues to expand its role as a leading decentralized oracle network, connecting blockchain applications with real-world data. As DeFi and Web3 applications grow, the demand for reliable oracles also increases. This alone makes Chainlink worth considering for your cryptocurrency investment portfolio. Tron (TRX) TRON does not receive as much attention as Ethereum or Solana, but it has quietly become one of the most widely used blockchains, especially for sending stablecoins like USDT. Its network supports smart contracts and applications, similar to Ethereum, but is cheaper to use. Additionally, Canary Capital has filed for a TRON ETF with staking features in April 2025, which could attract institutional investors if approved by the SEC.
