Ethereum has rapidly evolved from a niche blockchain project into a global digital innovation powerhouse. As the backbone of decentralized applications, it powers everything from financial platforms to digital art ecosystems. But what exactly makes Ethereum so powerful? In this guide, we’ll break down the core concepts—smart contracts, DeFi, and NFTs—in plain language, inspired by insights from Raymond Wu, co-founder of Asia’s leading NFT community, FOMO Dog Club.
Whether you're new to crypto or looking to deepen your understanding, this article will help you grasp why Ethereum is often seen as the next-generation internet protocol—and why so many investors, developers, and creators are betting big on its future.
Understanding Ethereum: More Than Just a Cryptocurrency
At its core, Ethereum is not just a digital currency like Bitcoin. It’s a decentralized computing platform that enables developers to build and deploy applications that run without interference, censorship, or third-party control.
While Bitcoin functions primarily as digital gold—a store of value—Ethereum acts as a programmable blockchain. This means it can execute complex logic through code, opening doors to entirely new digital economies.
What Are Smart Contracts?
A smart contract is self-executing code stored on the Ethereum blockchain. Think of it as a digital agreement that automatically fulfills its terms when predefined conditions are met—no lawyers, no intermediaries.
For example:
- If Alice sends 1 ETH to a smart contract, she automatically receives a digital collectible (NFT) in return.
- If Bob repays a loan with interest by a certain date, the collateral he locked is instantly released.
Smart contracts eliminate trust issues because the rules are transparent and enforced by code. Once deployed, they cannot be altered or tampered with.
Raymond Wu likens smart contracts to vending machines: "You put in money, make a selection, and get your item—no cashier needed." This automation is the foundation for DeFi, NFTs, and more.
DeFi: Decentralized Finance for Everyone
Decentralized Finance (DeFi) refers to financial services built on blockchain technology—without banks, brokers, or centralized institutions.
With DeFi, anyone with an internet connection can:
- Lend or borrow assets and earn interest
- Trade cryptocurrencies instantly
- Provide liquidity to trading pools
- Access insurance and derivatives
All of this happens through smart contracts on Ethereum. For instance, instead of depositing money into a bank savings account at 1% interest, users can lend their crypto via platforms like Aave or Compound and potentially earn higher yields—sometimes over 5%.
But DeFi isn’t risk-free. Smart contract vulnerabilities, market volatility, and impermanent loss are real concerns. That’s why education and caution are essential before diving in.

NFTs: Beyond Digital Art
Non-Fungible Tokens (NFTs) are unique digital assets verified on the Ethereum blockchain. Unlike cryptocurrencies such as ETH (which are interchangeable), each NFT has distinct properties and cannot be replaced by another identical item.
Originally popularized by digital art and collectibles—like Bored Ape Yacht Club or CryptoPunks—NFTs now represent:
- Virtual real estate in metaverse worlds
- In-game items and characters
- Music rights and royalties
- Event tickets and memberships
- Identity verification and credentials
Raymond Wu emphasizes that NFTs are not just speculative assets—they’re tools for ownership and community building. As co-founder of FOMO Dog Club, one of Asia’s most active NFT communities, he’s seen firsthand how NFTs create loyal, engaged groups around shared interests.
“An NFT isn’t just a JPEG,” Wu says. “It’s access, identity, and belonging—all secured by blockchain.”
Why Ethereum Stands Out
Ethereum’s dominance in the blockchain space comes down to network effects. With thousands of developers building on it, millions of users interacting daily, and billions of dollars locked in protocols, it has created a robust ecosystem that’s hard to replicate.
As Wu puts it:
“Trying to replace Ethereum is like trying to build another metro system in Taipei to compete with the existing MRT—it might be possible, but the cost, coordination, and user adoption would be enormous.”
Even major institutions like Amazon and Wall Street firms are exploring Ethereum-based solutions. High-profile figures such as Elon Musk and NBA star Stephen Curry have publicly supported or collected NFTs on Ethereum, further boosting its credibility.
Can You Invest With Limited Capital?
Absolutely. One of Ethereum’s strengths is accessibility. You don’t need thousands of dollars to get involved.
Here’s how to start small:
- Buy a fraction of ETH through exchanges
- Stake ETH to earn passive income (with minimums as low as 0.01 ETH via liquid staking)
- Participate in micro-investment DeFi pools
- Collect affordable NFTs from emerging artists
The key is understanding the technology behind your investment—not chasing hype.
Frequently Asked Questions (FAQ)
What’s the difference between Bitcoin and Ethereum?
Bitcoin is primarily a decentralized digital currency designed as a store of value. Ethereum is a programmable blockchain that supports smart contracts, enabling DeFi, NFTs, and other decentralized applications.
Is Ethereum safe to invest in?
Like all investments, Ethereum carries risks due to price volatility and regulatory uncertainty. However, its strong developer community, widespread adoption, and continuous upgrades (like the transition to proof-of-stake) make it one of the most resilient projects in crypto.
How do I buy Ethereum?
You can purchase ETH through regulated cryptocurrency exchanges using fiat currency (like USD or TWD). After buying, store it securely in a wallet you control—not just on an exchange.
What are gas fees on Ethereum?
Gas fees are transaction costs paid in ETH to process actions on the network (e.g., sending tokens or minting NFTs). Fees vary based on network congestion but have decreased significantly after recent upgrades.
Can NFTs make money?
Some NFTs appreciate in value and can be resold for profit. Others generate income through royalties when resold or unlock benefits like exclusive content or event access. However, many NFTs lose value—research is crucial.
What does the future hold for Ethereum?
Ethereum continues to evolve with upgrades focused on scalability, security, and sustainability. Future improvements aim to increase transaction speed and reduce costs, making it more accessible globally.
Final Thoughts: Don’t Miss the Next Wave
If Bitcoin was the first act of the crypto revolution, Ethereum is the second—and possibly more transformative—chapter. From redefining finance with DeFi to empowering creators through NFTs, Ethereum is laying the groundwork for a decentralized future.
As Raymond Wu discovered after his journey from skepticism to advocacy: understanding the technology is the first step toward meaningful participation.
Whether you’re investing, creating, or simply curious, now is the time to learn about Ethereum’s ecosystem.
