What Is Ethereum (ETH)?

Ethereum is more than just a cryptocurrency—it’s a decentralized platform that enables smart contracts and decentralized applications (dApps). These self-executing contracts run exactly as programmed without downtime, fraud, or third-party interference.

The native cryptocurrency of the Ethereum network is called Ether (ETH). It ranks as the second-largest cryptocurrency by market capitalization after Bitcoin and is widely traded and accepted globally.

With major companies like Microsoft, Toyota, and Intel participating in the Enterprise Ethereum Alliance (EEA), Ethereum continues to gain traction as a foundational technology for future digital innovation.

Why Buy Ethereum? 3 Key Benefits

Before jumping into how to buy ETH, let’s explore why so many people are adding it to their portfolios.

1. Strong Growth Potential

Ethereum powers thousands of decentralized finance (DeFi) platforms, NFT marketplaces, and blockchain-based games. As adoption grows across industries—from finance to supply chain management—the demand for ETH increases.

The transition to Ethereum 2.0, which improves scalability and energy efficiency, has further strengthened investor confidence. With institutional interest rising and real-world use cases expanding, ETH’s long-term value outlook remains positive.

2. Invest with Small Amounts

You don’t need thousands of dollars to get started. Most exchanges allow fractional purchases, meaning you can buy a portion of one ETH—ideal for beginners testing the waters.

For example:

This flexibility makes Ethereum accessible to anyone, regardless of budget.

3. Trade Anytime, Anywhere

Unlike traditional stock markets, cryptocurrency markets operate 24/7, 365 days a year. Whether you're a busy professional or a student with limited daytime availability, you can buy or sell ETH whenever it suits your schedule.

This round-the-clock access allows traders to react quickly to market movements and capitalize on opportunities as they arise.

Frequently Asked Questions (FAQ)

Q: Can I buy Ethereum with a credit card?
A: While direct credit card purchases are not supported on most Japanese exchanges, you can deposit Japanese yen via internet banking or quick transfers and use those funds to buy ETH.

Q: Is it safe to buy Ethereum on overseas exchanges?
A: Due to stricter regulations from Japan’s Financial Services Agency (FSA), many international platforms like Binance and BitMEX have discontinued services for Japanese users. For security and compliance, domestic exchanges are currently the safest choice.
