How to Profit in Web3.0 and Key Points to Watch Out For

What Is Web3.0?

Web3.0 refers to a decentralized internet designed to address challenges in the current online landscape. Traditional Web2.0 models saw large corporations centrally managing user data. In contrast, Web3.0 uses blockchain technology to give individuals control over their own data and assets.

Web3.0 offers several advantages, including enhanced security, greater service stability, and direct transactions between businesses and users. Built on public blockchains, this decentralized architecture has enabled use cases such as NFT and crypto-based financial transactions and autonomous organizational management.

Also known as the decentralized internet, Web3.0 is an innovative concept that aims to distribute data ownership through blockchain technology. This enables a move away from the dominance of major corporations, allowing for a more democratic and transparent online environment through decentralized information management.

The main benefits of Web3.0 include:

Enhanced Security: Blockchain technology prevents data tampering and leaks. Decentralized data management eliminates single points of failure, significantly reducing hacking risks. Individuals can manage their own data, strengthening privacy protection and preventing unauthorized third-party data usage.

Greater Service Stability: Decentralized networks help avoid outages caused by server failures or censorship. Without dependence on central servers, there’s no risk of unilateral service suspension by specific companies or governments. Incentive mechanisms for network participants also drive autonomous service maintenance and improvement.

Direct Transactions Between Businesses and Users: By removing intermediaries, transaction costs and fees can be significantly reduced. Smart contracts automate and increase transaction reliability, ensuring contract execution. This creates a fairer and more transparent environment for transactions.

How to Earn in Web3.0

Web3.0 enables diverse monetization methods that traditional internet models never offered. Below are six representative ways to earn in the Web3.0 ecosystem.

Earning Through Cryptocurrency Investment

Cryptocurrencies (also known as virtual currencies) are digital assets traded online. Unlike fiat money, cryptocurrencies have no fixed price—they fluctuate constantly according to market supply and demand. The basic investment strategy is straightforward: buy low and sell high, but success depends on market analysis and timing.

Cryptocurrency investment is attractive due to 24/7 trading, the ability to start with small amounts, and the potential for significant short-term gains because of high volatility. However, this volatility also means higher risk, so caution is essential.

Key Tools and Services

Coincheck: One of Japan’s largest crypto exchanges, Coincheck offers around 20 cryptocurrencies, including Bitcoin and Ethereum. It features a beginner-friendly interface and lets you start investing with as little as ¥500. Its mobile app is robust, making trading easy from anywhere.

SBI VC Trade: Operated by the SBI Group, this trusted exchange offers about 10 cryptocurrencies, including Bitcoin and Ripple. You can start investing from just ¥100, and the backing of a major financial group ensures strong security and reliability.

bitFlyer: Japan’s first crypto exchange, with a long operating history. It supports about 10 cryptocurrencies, such as Bitcoin and Litecoin, with investments starting from ¥100. Users benefit from a fast trading system and multiple payment options.

Earning Through NFT Investment

NFTs, or Non-Fungible Tokens, are unique digital assets recorded on the blockchain. NFTs are used in digital art, music, video, game items, and more, with blockchain technology providing verifiable proof of ownership and copyright.

NFT investment is appealing because you can own rare digital items, support creators directly, and potentially benefit from future value appreciation. The NFT market has grown rapidly, with art pieces sometimes selling for hundreds of millions of yen. Investors buy NFTs anticipating value growth, then sell at higher prices when the timing is right.

Key Tools and Services

OpenSea: The world’s largest NFT marketplace, supporting a range of categories such as digital art, game items, and domain names. It supports multiple blockchains including Ethereum and Polygon, making it popular with both beginners and advanced users.

Rarible: An NFT marketplace built on Ethereum, where you can trade digital art, music, video, and more. Creators can mint and sell their own NFTs, and the platform features its own governance token, RARI.

Earning Through DeFi

DeFi, or Decentralized Finance, is a collective term for decentralized financial ecosystems built on public blockchains. There are no central management entities—DeFi services are provided automatically via smart contracts.

DeFi’s innovative qualities include open, equal access to financial services, 24/7 operation, and potentially higher yields than traditional financial institutions. Services like lending, borrowing, investing, and currency issuance—previously managed by centralized entities—are now accessible without intermediaries.

Ways to earn with DeFi include:

Lending: Lend your cryptocurrencies to other users to earn interest. Borrowers can obtain crypto by providing collateral.

Staking: Deposit certain cryptocurrencies into a network to help maintain it and earn new tokens as rewards.

Liquidity Mining: Provide crypto pairs to decentralized exchanges and receive a portion of transaction fees as rewards.

Key Tools and Services

Uniswap: One of the largest decentralized exchanges (DEX) in the world. Crypto assets are exchanged directly between users—no centralized intermediaries or market makers. Swap rates are set automatically based on liquidity pool balances.

Earning Through NFT Games

NFT games—sometimes called blockchain games or GameFi—are built on blockchain technology. Their standout feature is that in-game characters and items you create, develop, or acquire are minted as NFTs with real-world value.

In traditional games, companies managed in-game items, and players lacked true ownership. In NFT games, players genuinely own in-game assets and can freely buy, sell, or trade them. This enables the "Play to Earn" model—a new way to earn by gaming.

Ways to earn in NFT games include:

Collecting In-Game Rewards: Play games to earn crypto or NFT items as rewards.

Selling Characters or Items: Sell developed characters or rare items on NFT marketplaces for profit.

Renting Out Characters: Lend your characters to other players for rental fees.

Key Tools and Services

Axie Infinity: A leading NFT game on Ethereum. Players breed and battle cute "Axie" characters and can create new ones through breeding. Axies and virtual land can be traded on the marketplace, and the game features its own governance token, AXS.

The Sandbox: An Ethereum-based metaverse platform where you can create and share virtual worlds. NFTs such as virtual land and avatars can be traded, and the in-game economy runs on the SAND utility token.

CryptoKitties: The original NFT game on Ethereum, where you create, collect, and breed unique "CryptoKitty" cats. Each has unique genes, and rare traits can fetch high prices.

Earning by Working at Web3.0 Companies

Web3.0 companies operate businesses in decentralized internet domains, including blockchain development, NFT platforms, crypto exchanges, and DeFi protocol development.

Working for a Web3.0 company offers many advantages. You’ll work with advanced technologies like blockchain and NFTs and develop valuable technical skills. Many companies offer part of your pay in crypto or NFTs, and as the company grows, so may the value of your compensation.

The Web3.0 industry is expanding rapidly, with strong demand for engineers, marketers, designers, community managers, and more. Career opportunities abound.

Ways to get hired by Web3.0 companies include:

Earning by Working in a DAO (Decentralized Autonomous Organization)

DAOs, or Decentralized Autonomous Organizations, are new community and organizational structures built on blockchain technology. DAOs have no central decision-makers; members govern democratically through voting and governance tokens.

Traditional organizations are hierarchical, with executives and shareholders making decisions and employees following instructions. In DAOs, all participants can contribute equally to decision-making and help set the organization’s direction.

DAO participation offers exposure to cutting-edge technology and global collaboration. Members earn rewards—crypto or NFTs—based on contributions, and reward values may grow as the DAO succeeds.

DAO work is usually project-based, not governed by traditional employment contracts. You can join multiple DAOs at once and allocate your time and skills flexibly.

Major Global DAOs

MakerDAO: A leading DAO that issues and manages the DAI stablecoin. DAI is pegged to the US dollar and managed autonomously on-chain. MKR token holders vote on key issues like DAI issuance conditions and collateralization ratios.

NounsDAO: A unique DAO that raises funds by auctioning a newly generated NFT artwork (Noun) each day. The community votes on funding allocation, and NFT holders automatically become DAO members with voting rights.

Major DAOs in Japan

Ninja DAO: The official DAO for the Japanese NFT collection "CryptoNinja" and one of Japan’s largest. Projects span derivative works, game development, and education. Anyone can join for free and earn rewards based on their contributions.

Kunimitsu DAO: Founded by Hirotake Kunimitsu, CEO of "FiNANCiE" (Crowdfunding 2.0), this DAO aims to grow globally competitive Japanese unicorns in Web3 and the metaverse, supporting entrepreneurs and investing in new ventures.

Key Considerations for Earning in Web3.0

Web3.0 holds tremendous promise, but also brings significant risks. To earn safely and sustainably, it’s essential to understand and address the following three points:

Beware of Fraudulent Services and Solicitations

Web3.0 remains new, with legal frameworks and regulations lagging behind. Malicious actors frequently attempt to deceive users. Common scams include:

High-Return Investment Schemes: Offers guaranteeing profits or "monthly returns of XX%" are almost always scams. All investments carry risk—there’s no such thing as guaranteed profit.

Fake NFT Projects: Impersonating well-known NFT projects using fake websites or social media accounts. Always verify official URLs and handles.

Phishing Scams: Fake emails or messages seek to steal wallet private keys or passwords. Never share your private key.

Ponzi Schemes: Early returns are paid from new investors’ money, but such schemes always collapse eventually.

To protect yourself, take these precautions:

• Always verify the project’s official website and whitepaper before investing
• Check reputations on social media and in communities
• Check the development team’s track record and transparency
• Never invest in schemes promising high returns
• Never share your private key or password
• Rely only on trustworthy information sources

Understand That Legal Frameworks Are Still Evolving

Web3.0, as a decentralized blockchain-powered internet, does not always fit into existing legal and regulatory frameworks, resulting in significant legal uncertainty.

Tax Issues: Profits from cryptocurrency or NFT trading are taxable in many countries, but tax rules can be unclear. It’s important to know the proper reporting methods. With crypto-to-crypto trades, NFT sales, and DeFi profits, each has unique tax implications.

Legal Status of DAOs: DAOs are a new form of organization, and most countries haven’t defined their legal status. Contracts and liability can be ambiguous.

Securities Law Implications: Some tokens may be classified as securities and become subject to securities regulations. Always understand the legal nature of a token before investing.

International Regulatory Differences: Web3.0 is global, so regulations vary by country. You may need to consider both your own country’s laws and those of your counterparties.

To address these challenges, follow these steps:

• Keep detailed records of all crypto and NFT transactions
• Consult a professional (such as a tax accountant) for tax matters
• Stay up to date on changes to laws and regulations
• Consult legal experts when in doubt
• Act responsibly and comply with all regulations

Be Prepared to Take Full Personal Responsibility

One of Web3.0’s defining features is decentralization—it gives users full control over their data and assets, but also full responsibility.

Wallet Management: If you lose your wallet’s private key or recovery phrase, it’s nearly impossible to recover your assets. Unlike banks, there’s no password reset or customer support. Wallet security is entirely your responsibility, with no recourse for loss or theft.

Hacking Risks: If your wallet is hacked or your private key stolen via phishing, recovery is extremely difficult. You must implement security measures such as two-factor authentication and hardware wallets yourself.

Project Failure Risks: If a project fails or the development team abandons it, you may lose your investment. Funds can also be lost due to smart contract bugs or hacks.

Market Volatility: Crypto and NFT prices fluctuate more than stocks. Asset values can halve in a short time. Only invest what you can afford to lose.

Regulatory Risks: Government regulation can render certain services unavailable or cause asset values to plummet.

To manage these risks, adopt these practices:

• Store private keys and recovery phrases in multiple secure places
• Invest only surplus funds—never your entire holdings
• Diversify your investments; don’t focus solely on one project
• Implement robust security (two-factor authentication, hardware wallets, etc.)
• Keep learning and stay informed
• Understand all risks and accept full personal responsibility

Web3.0 is highly promising, but also risky. To succeed, keep your knowledge current and proceed with caution and responsibility.

How Web3.0 Is Changing the Way We Work

Web3.0’s rise may fundamentally transform work and lifestyle. New paradigms are emerging, distinct from traditional employment and corporate structures. Below are three key ways Web3.0 is changing work:

Project-Based Work Unbound by Organizations

Web3.0 shifts work from "organization-based" to project-based. At the center of this shift are new structures like DAOs (Decentralized Autonomous Organizations).

Traditionally, people belonged to specific companies and fulfilled assigned roles. In Web3.0, DAOs—formed for individual projects, not as fixed organizations—become the main workplace.

Individuals join DAOs based on their interests and skills. This is fundamentally different from traditional employment; DAO members contribute as part of a community and are rewarded based on contribution, not by employment contract.

This new work style offers these advantages:

Freedom from Geography: DAOs exist online, so you can work from anywhere. No office commute—work wherever you want.

Flexible Scheduling: Most DAOs don’t set strict hours, so you can work around your lifestyle.

Project Choice: Choose only projects that interest you and add value—no more unwanted assignments.

Transferable Skills: Experience and skills from one project can be applied to others.

Diverse Use of Your Skills and Abilities

Because DAOs often don’t require employment contracts, it’s common to join multiple DAOs at the same time. This is a new paradigm, distinct from the traditional "one-company" model.

Your skills aren’t limited to one role. For example, as a designer, you could:

Create NFT Art: Mint and sell your art as NFTs.

Design Metaverse Spaces: Build immersive virtual experiences.

Brand DAOs: Design logos and visual identities for DAOs.

Design NFT Game Characters: Create game characters and items.

Web3.0 UI/UX Design: Design user interfaces for decentralized apps.

Engineers can develop smart contracts, build DeFi protocols, or create NFT marketplaces. Marketers can manage communities and develop strategies for multiple projects.

Benefits of this work style include:

Diversified Income: Multiple projects mean multiple income streams, protecting you from any single project’s failure.

Broader Skill Application: Use all your skills across diverse projects for maximum impact.

Continuous Learning: Involvement in various projects expands your knowledge and experience, supporting ongoing growth.

Expanded Network: Work on multiple projects and build a wide professional network.

Choosing Work That Aligns with Your Values and Purpose

Web3.0 empowers you to choose work that reflects your values and purpose—enabling meaningful careers that were difficult under traditional employment models.

Conventional jobs often prioritized salary, stability, or career path, making it hard to pursue values-driven work. In Web3.0, you can choose work that matches your values, such as:

Social Contribution and Environmental Protection: Join projects addressing issues such as climate change, poverty reduction, or education. For example, tokenizing carbon credits as NFTs or supporting education in developing countries through DAOs.

Arts and Culture: Support artists or preserve cultural heritage digitally.

Open Source Development: Contribute to freely accessible software and protocols.

Decentralization and Democracy: Join projects that challenge centralized power and promote fairness and democracy.

Web3.0 also provides reward mechanisms for your contributions, such as:

Token Rewards: Receive governance or utility tokens for your work. If the project succeeds, token value may rise.

NFT Rewards: Earn commemorative or utility NFTs for achievements.

Profit Sharing: Share project profits based on your contribution.

Voting Rights: Gain voting power in project governance based on your contributions.

Benefits of this work style include:

Increased Motivation: Work on projects you care about, boosting engagement and results.

Long-Term Satisfaction: Experience deeper fulfillment from social impact and personal growth—not just financial rewards.

Community Connection: Collaborate with like-minded people for a strong sense of belonging.

Visible Growth: See your contributions directly impact project success.

Web3.0’s impact on work extends beyond technology, shaping our values and perspectives. Free from organizational constraints, you can apply your skills broadly and choose work that matches your values—offering a new path to a more rewarding life.

Summary

Earning with Web3.0 increases your freedom and opportunities, but also brings significant risks and responsibilities. There are many ways to earn—crypto investing, NFT investing, DeFi, NFT gaming, working at Web3.0 companies, and participating in DAOs—each with unique benefits and risks.

Web3.0 remains an emerging field, with incomplete legal frameworks and limited social awareness. Blockchain technology also faces technical challenges and limitations, and the risks of fraud and misconduct are real.

With the right knowledge and caution, Web3.0 can provide new sources of income and work. The key is to keep learning, understand the risks, and act responsibly.

To succeed in Web3.0, keep these points in mind:

• Be vigilant for scams—only join trusted projects
• Learn about law and taxes and manage them properly
• Implement strong security and protect your assets
• Diversify your investments and manage risk wisely
• Continuously learn and stay updated on technology and trends
• Engage in communities to share information and network

Web3.0 is a revolutionary technology creating a new internet era. By maximizing its potential and managing risks, you can achieve greater freedom and a more fulfilling career and lifestyle.
