You keep seeing "digital currency" in the news, but what exactly is it? How is it different from the money in your WeChat or Alipay? Today we'll explain it in the simplest terms possible. If you're interested, register an account to experience it firsthand — APP download here.
What Digital Currency Actually Is
In the broadest sense, digital currency is any currency that exists in digital form. But in everyday discussion, it usually refers to two things:
The first is cryptocurrency — like Bitcoin, Ethereum, and others. These are based on blockchain technology, not issued or controlled by any government or bank. They're decentralized. This is what most people mean when they say "digital currency."
The second is Central Bank Digital Currency (CBDC) — like China's digital yuan (e-CNY). This is legal digital currency issued by a country's central bank — essentially still the same currency, just in digital form.
Though both are called "digital currency," they're fundamentally different. This article mainly discusses the first type — cryptocurrency.
How Crypto Differs from WeChat/Alipay Money
Your WeChat balance is essentially still yuan in a bank, just using a different medium for payment. It's backed by the central bank's credit and cleared through the banking system.
Cryptocurrency is different. Bitcoin doesn't depend on any bank or government. It's maintained by thousands of nodes across the blockchain network, with all transactions transparently recorded on-chain and immune to tampering.
A simple analogy: WeChat/Alipay is like bank money with a new interface; cryptocurrency is an entirely independent monetary system.
Why Cryptocurrency Has Value
This is the most common question from beginners. Bitcoin is intangible and invisible — why is it worth so much?
Scarcity — Bitcoin's total supply is only 21 million, forever. This scarcity is similar to gold.
Network effect — The more people use and accept it, the more valuable it becomes. Over 100 million people globally now use cryptocurrency.
Practical utility — Beyond investment, cryptocurrency has real applications in cross-border transfers, decentralized finance, NFTs, and more.
Market consensus — When enough people believe it has value, it genuinely does. Currency itself is a social contract.
Common Digital Currencies
Bitcoin (BTC) — The first and most famous cryptocurrency, largest by market cap, called "digital gold."
Ethereum (ETH) — Not just a currency but a platform for smart contracts, with many decentralized applications built on top.
USDT and USDC — Stablecoins pegged to $1, serving as intermediary currencies in trading.
BNB — Binance's native token, used for fee discounts and platform activities.
Solana, Cardano, Polygon — Next-generation blockchain projects, each with unique innovations.
How to Get Started with Digital Currency
Step 1: Build basic knowledge. Understand the basics of Bitcoin and blockchain — no need to go deep, just know what it's about.
Step 2: Register an exchange account. Sign up on Binance and complete verification — the whole process takes under ten minutes.
Step 3: Make a small purchase. Buy some USDT through C2C, then try buying a tiny bit of Bitcoin to feel the process.
Step 4: Keep learning. Follow market developments and learn basic technical analysis and risk management.
Know the Risks
Digital currency price volatility far exceeds stocks — 10% or even 20% swings in a single day are common. So only invest money you can afford to lose entirely without affecting your life.
Also, there are many scams using the digital currency label. Trade on legitimate major platforms, don't believe any "guaranteed profit" claims, and don't transfer coins to strangers.
With this foundational knowledge, you have a general understanding of digital currency. Whether to participate and how much is your own choice.
