Ethereum has played a central role in the cryptocurrency market for many years. As the world's second-largest cryptocurrency after Bitcoin, Ethereum leads the industry by providing various utilities such as DeFi (Decentralized Finance), NFTs (Non-Fungible Tokens), and gaming as a smart contract platform. As of April 2026, Ethereum continues to solidify its position as the 'undisputed king of altcoins' and is once again drawing significant attention. Ethereum's current market capitalization stands at $279 billion, with its price hovering around $2,318. This represents a robust 21.87% increase year-to-date, demonstrating strong growth. Notably, Ethereum maintains its dominant position in the smart contract platform sector, accounting for approximately 14% of the total cryptocurrency market capitalization. Currently, over 3,000 dApps (decentralized applications) operate on the Ethereum network, illustrating that Ethereum functions as a core infrastructure for a broad blockchain ecosystem, beyond just being a cryptocurrency. Now, Ethereum is ushering in new changes to the cryptocurrency market with a major upgrade called 'Glamsterdam'. This update focuses on significantly reducing gas fees for Layer-2 networks, which is expected to provide direct economic benefits to users and developers while stimulating overall market activity. The Glamsterdam upgrade specifically aims to substantially enhance the performance of major Layer 2 solutions such as Arbitrum and Base. Layer 2 is a technology developed to process transactions faster and more affordably on top of the Ethereum mainnet. Layer 2 solutions, gaining prominence as a key method to address Ethereum's scalability issues, facilitate faster processing of more transactions and reduce costs on the network. This allows Ethereum to overcome its long-standing weaknesses of 'slow and expensive transactions,' laying the groundwork for both expanding its user base and attracting institutional investors. Currently, the Total Value Locked (TVL) in Layer 2 networks exceeds $42 billion, and the market capitalization of the entire Layer 2 altcoin sector has surpassed $100 billion. This clearly indicates that Layer 2 is one of the fastest-growing sectors in the overall cryptocurrency market. Popular Layer 2 altcoins like Arbitrum, Optimism, and Polygon have already achieved significant success, attracting numerous developers and users. Creating New Opportunities in the Korean DeFi and NFT Markets These Layer 2 networks offer an attractive environment for developers building DeFi applications, NFT platforms, and gaming experiences. The Glamsterdam upgrade is expected to help these Layer 2 altcoins generate more real-world utility. Reduced gas fees will encourage users to participate in more transactions, creating a virtuous cycle that improves the overall user experience and expands the ecosystem. Layer 2 altcoins are particularly important as they offer an opportunity to gain exposure to Ethereum's growth without the participation limitations previously imposed by high transaction fees. The increase in institutional investment is also highlighted as a significant outcome of this upgrade. In the past, the high volatility of the cryptocurrency market made it a difficult area for institutional investors to access easily. However, in recent years, with the increased stability and practicality of Ethereum and other major cryptocurrencies, institutional investors are observed to be entering the market more actively. Technological advancements like the Glamsterdam upgrade are paving the way for institutional investors to participate in the Ethereum ecosystem on a larger scale within a regulated environment. Notably, global banks and asset managers have begun adopting Ethereum as a trading and settlement system within an enhanced regulatory and secure environment. As Ethereum further solidifies its role as a primary settlement layer for global DeFi, institutions are recognizing the reliability and scalability of the Ethereum network. These changes contribute to the overall maturation of the cryptocurrency market and act as factors that enhance its long-term stability. These shifts in the global cryptocurrency market are expected to impact national markets as well. Countries with high internet penetration and tech-savvy populations are rapidly adopting cryptocurrencies and blockchain-related technologies. The DeFi sector is one area of increasing interest among many investors, and the NFT market is also gaining attention through unique content and artworks. Here, Ethereum is utilized as a major means of payment, and the gas fee reduction brought by the Glamsterdam upgrade will offer significant opportunities for both individual investors and businesses. The advancement of Layer 2 technology is a critical factor determining the future of the Ethereum ecosystem. Layer 2 solutions are pursuing independent innovations while maintaining compatibility with the existing Ethereum mainnet. Th
