Introduction to Ethereum: Benefits of Using ETH for Fan Activities

Introduction: Why Ethereum for OSHI-Katsu Activities Now?

The world of oshi activities (supporting your favorite artists/idols) is about to change dramatically. Where cash and credit cards have been the mainstream payment methods for fan activities, a new option has emerged: payments using Ethereum, the world's most trusted blockchain.

What is Ethereum? A Beginner's Guide for Fans

The World's Second-Largest Cryptocurrency

Ethereum is the world's second-largest cryptocurrency after Bitcoin. Since its launch in 2015, it has been used worldwide as more than just a currency – it's "programmable money."

Example:

• Bitcoin = Like physical cash
• Ethereum = Like a rechargeable transit card (Suica) that automatically adds rewards and points

The ETH Currency

The currency used on the Ethereum network is called "ETH" (Ether). While 1 ETH is approximately 640,000 yen (as of September 2025), you can use small amounts like 0.001 ETH, making it perfect for small fan-related purchases.

5 Benefits of Using ETH for Oshi Activities

1. 🌍 Global Accessibility

When your oshi is an international artist, ETH becomes your powerful ally.

Specific Examples:

• Purchase K-pop idol goods directly from fan sites
• Acquire exclusive NFT content from American artists
• Buy concert tickets from European venues

You can engage in oshi activities worldwide without worrying about foreign exchange fees.

2. 🎫 Perfect Compatibility with NFTs

Ethereum is the birthplace of NFTs (digital collectibles).

Fan Activity Applications:

• Limited edition digital photo cards of artists
• Special seat concert tickets (with anti-scalping features)
• NFT-based fan club memberships
• One-on-one online call rights with your oshi

OSHIPay's GENESIS NFT is also issued on Polygon (Ethereum's Layer 2), making it part of the Ethereum ecosystem.

3. 💎 Asset Value Potential

ETH is not just a payment method but an asset with fluctuating value.

Benefits:

• Your oshi activity funds might grow unexpectedly
• Potential for long-term asset building

※ Note: Prices can also decrease, so we recommend using only funds you can afford to risk

4. 🔒 High Security and Transparency

Ethereum is one of the world's most robust blockchains.

Peace of Mind Features:

• Transaction history cannot be tampered with
• All oshi activity expenses are recorded (convenient for tax filing)
• OSHIPay's non-custodial approach means you control your own assets

5. 🚀 Cutting-Edge Fan Experiences

Using Ethereum enables unprecedented oshi activities.

New Experiences:

• Automatic reward distribution via smart contracts
• Participation in fan community governance through DAOs
• Oshi activity fund management through DeFi integration
• Interactions with your oshi in the metaverse
