Bitcoin (BTC): The basis of each cryptocurrency portfolio

? Bitcoin is often known as "digital gold" as the earliest and most widely known cryptocurrency. Entering 2025, its market performance once again amazed the world, with prices breaking through the $123,000 mark, setting a new record of historical highs. With a fixed supply cap of 21 million coins, a decentralized architecture and a powerful cybersecurity mechanism, Bitcoin has become a popular store of value in the digital age.

Institutional interest in crypto assets continues to heat up, and more and more companies and even national entities are beginning to include Bitcoin in their asset allocation. The official approval of spot Bitcoin ETF further lowered the entry threshold for ordinary investors and injected a lot of liquidity and confidence into the market. The reason why Bitcoin has been prosperous is its resilience after multiple rounds of bull and bear cycles, and its unique position as an anti-inflation tool and "anchored asset" in the field of crypto. For any investor who wants to build a solid portfolio, Bitcoin remains an indispensable core position, with stability, wide recognition and long-term value-added potential.

Ethereum (ETH): Smart Contract Power

? Ethereum has firmly ranked second largest cryptocurrency in the world and has become the backbone of the decentralized application ecosystem. As of July 2025, the ETH transaction price was approximately US$3,700, and it is the core platform for smart contracts, decentralized finance (DeFi), NFT and various blockchain innovations. Since its successful shift to the Proof of Stake (PoS) mechanism, Ethereum has greatly improved energy efficiency and network scalability, paving the way for wider application implementation.

The real advantage of Ethereum lies in its versatility and continuous evolution. Most DeFi protocols, NFT trading platforms and Layer-2 solutions are built on or integrated with Ethereum to promote the continued prosperity of the ecosystem. The network is regularly upgraded, such as sharding technology and data availability improvements, effectively alleviating congestion and controlling transaction costs. For investors, Ethereum integrates first-class security guarantees, practical application scenarios and huge growth space brought by the expansion of the Web3 ecosystem. Its huge developer community and emerging real-life use cases make ETH the first choice for crypto investments pursuing long-term value and technological influence.

Ripple (XRP): Fast and cost-effective global payments

?XRP, a digital asset designed specifically to optimize cross-border payments, has established a solid position in the financial field. In July 2025, the price of XRP was about US$3.5. With its second-level settlement speed and extremely low handling fees, it has become an ideal choice for financial institutions to achieve efficient capital flow. The technical characteristics of XRP ledgers are significantly better than traditional banking systems, and even surpass most mainstream cryptocurrencies in performance.

The important driving force for XRP in 2025 comes from the clarification of the legal environment – a settlement with long-term litigation with U.S. regulators has cleared key uncertainties. This progress has rekindled interest from banks and payment institutions around the world in Ripple technology, and has promoted the rapid expansion of partnerships and practical application cases. Ripple's growing network of financial partners is accelerating the penetration of XRP in the global payment system. For investors, XRP not only has the stability of leading crypto assets, but also provides a unique window to participate in the integration process of traditional finance and blockchain, and is a high-quality option to diversify its investment portfolio.

Solana (SOL): High-speed blockchain for decentralized applications

? Solana has rapidly grown into an important platform for decentralized applications with its amazing transaction processing capabilities and low fees. In July 2025, the SOL price was close to US$200, reflecting its continued strong momentum as on-chain activity surged. By combining the Proof of Stake (PoS) and Proof of History (PoH) mechanism, Solana achieves high-performance outputs of thousands of transactions per second, especially suitable for high frequency and low latency application scenarios.

The Solana ecosystem is booming, bringing together a large number of DeFi, NFT, GameFi and payment projects. Its ability to maintain smooth operation under high loads has become a key advantage in attracting developers and users. Recent network optimization has significantly enhanced system stability and scalability, making up for some of the problems exposed in the early rapid growth stage. As the demand for blockchain applications continues to rise, Solana has become a leader in smart contract platforms with its leading technical strength and active community ecosystem. For investors seeking a combination of high growth potential and technological innovation, Solana is undoubtedly an attractive component of the portfolio.

Chainlink (LINK): The basic infrastructure of smart contracts

? Chainlink has become the key infrastructure of the blockchain ecosystem, seamlessly connecting smart contracts with off-chain data through a decentralized oracle network. As of July 2025, LINK is priced at about US$20 and is widely used in DeFi platform and enterprise-level blockchain projects. The network provides secure and trustworthy external data sources, such as market prices, interest rates, event results, etc., which is the basic guarantee for the normal operation of many decentralized applications.

With the continuous implementation of new cooperative projects, including deep integration with large financial institutions and technology companies, Chainlink's application scope continues to expand. Its exploration in cross-chain interoperability is also becoming increasingly in-depth, helping to achieve efficient communication between different blockchains. As the industry's dependence on reliable data increases, Chainlink's technical value is becoming increasingly prominent. For investors, LINK represents an opportunity to participate in the construction of underlying infrastructure. It can not only share the dividends of DeFi ecological growth, but also benefit from its continuous innovation in pledge services, advanced data markets, etc. In the future, Chainlink's strategic position in the crypto world is expected to be further consolidated.
