Do you often hear people talking about Web3, NFTs, and blockchain, but feel completely confused and unsure where to start? You are not alone. Many people want to seize Web3 investment opportunities, yet worry that the risks are too high and the concepts too complex. This Web3 beginner’s guide is designed specifically for newcomers. It will gradually introduce you to the core concepts of Web3, teach you how to invest in Web3, and provide the most practical Web3 wallet recommendations, allowing you to master all the fundamental knowledge in one article and take your first step into Web3 investing.
Simply put, Web3 is the next evolutionary stage of the internet. If Web1 was “Read-Only”, such as browsing news websites, and Web2 is “Read-Write”, such as creating content on Facebook and Instagram, then Web3 is “Read-Write-Own”, emphasizing the return of data and asset ownership from large corporations back to individual users.
To help you understand more clearly, the table below allows you to quickly grasp the core differences among the three generations of the internet:
| Characteristics |
Web1 (Approximately 1990–2004) |
Web2 (Approximately 2004–2020) | Web3 (Approximately 2020–Present) |
| Core Concept | Information Connectivity | Social Connectivity & Platform Economy | Value Connectivity & Ownership Economy |
| User Role | Information Consumer (Read-Only) | Content Creator (Read-Write) | Network Owner (Read-Write-Own) |
| Data Ownership | Controlled by Website Owners | Controlled by Large Technology Companies | Controlled by Users Themselves |
| Representative Applications | Yahoo, Netscape | Facebook, Google, YouTube | Bitcoin, Ethereum, Uniswap |
| Key Technologies | HTML, HTTP | Social Media, Cloud Computing | Blockchain, Cryptocurrency, AI |
After understanding the basic concepts, the most practical question is: how should ordinary individuals invest in Web3? Currently, there are three mainstream methods, each with different approaches and risks. Choosing the path that suits you is extremely important.
Investing in cryptocurrencies is the most direct way to enter Web3. Just like buying stocks means purchasing shares of a company, buying cryptocurrencies is equivalent to being optimistic about the future development of a blockchain ecosystem (such as Bitcoin or Ethereum). Bitcoin (BTC) is regarded as “digital gold” and serves as a store of value, while Ethereum (ETH) is a smart contract platform on which many Web3 applications (dApps) are built.
How to Get Started?
NFT (Non-Fungible Token) is a unique digital asset that can represent anything: artwork, music, in-game items, memberships, and more. Each NFT has a unique code recorded on the blockchain, proving your ownership of that digital item. Investing in NFTs is not only about their artistic value, but more often about the community value behind them, the utility they provide (such as event access or in-game privileges) and their potential for appreciation.
Sources of NFT Value:
DeFi (Decentralized Finance) refers to a financial system built on blockchain technology, aiming to replace intermediaries such as traditional banks and brokerages. Through DeFi, you can conduct lending, trading, and earn interest, with greater transparency and efficiency.

Web3 is full of opportunities, but the risks should not be ignored. Beginners must be mentally prepared and implement proper risk management before entering the market.
To truly “own” your Web3 assets instead of storing them on an exchange, you need a Web3 wallet. This wallet serves as your identity and vault in the decentralized world, and all operations must go through it.
A Web3 wallet does not store “money”, but rather a pair of “keys” (private key and public key), which authorize you to control assets on the blockchain. Wallets are mainly divided into two categories:
For beginners, it is recommended to start with a user-friendly hot wallet. After becoming familiar with the operations and as assets increase, consider purchasing a cold wallet to enhance security.
There are many different Web3 wallets on the market. The following are some of the most popular and comprehensive options:
| Wallet Name | Type |
Main Features |
Supported Networks | Suitable Users |
| MetaMask | Hot Wallet (Browser Extension/Mobile App) | Has the largest user base and the broadest ecosystem, and is almost the standard wallet for EVM chains | Ethereum, BNB Chain, Polygon and other EVM-compatible chains | All Web3 users, especially DeFi and NFT users |
| Binance Web3 Wallet | Hot Wallet (Built into the Binance App) | Seamlessly connects to the Binance exchange, simplifies transfers, and enhances security with MPC technology | Multi-chain support | Binance exchange users, beginners seeking convenient operations |
| OKX Web3 Wallet | Hot Wallet (Built into the OKX App) | Powerful features, integrates DEX, NFT marketplace, and earning platforms for a one-stop experience | Multi-chain support, supports the BTC ecosystem | Advanced users seeking integrated functions and a one-stop experience |

MetaMask is currently the most widely used Web3 wallet. Follow the steps below to complete the setup in just a few minutes:
A: Very high. The Web3 sector is still in its early stage of development, with significant market volatility and a high project failure rate. Beginners should adopt a learning mindset and only invest funds they can afford to lose (such as 1 to 5 percent of their total portfolio). Never put all your funds “All-in”. It is recommended to start with mainstream cryptocurrencies such as Bitcoin and Ether, and then gradually explore other areas.
A: If you lose your seed phrase, it essentially means you have permanently lost all the assets in your wallet. No one (including the wallet developer) can help you recover them. This is the cost of decentralization. You have 100 percent control over your assets, but you must also bear 100 percent responsibility for safeguarding them. Therefore, physically backing up and securely storing your seed phrase is of utmost importance.
A: It depends on your situation. Most exchanges have very low minimum transaction amounts, and you can purchase cryptocurrencies with just dozens to one hundred Hong Kong dollars. The key is not the amount, but the process of beginning to learn and gain experience. It is recommended to start with a small amount, personally complete the process of buying coins and transferring them to your Web3 wallet, and accumulate experience rather than investing a large amount at the beginning.
A: This depends on the regulations in your jurisdiction. Tax policies on crypto assets vary significantly across countries and regions. For example, some jurisdictions treat them as capital gains, which may require paying capital gains tax. It is recommended to consult a local tax professional to clearly understand your legal responsibilities and avoid unnecessary trouble.
Congratulations! By reading this far, you have already mastered the basic concepts of Web3, the mainstream investment methods, and how to choose and set up a Web3 wallet.
