Cryptocurrency has become one of the most talked-about topics in finance and technology over the past decade. Despite its growing popularity, many people still ask: What exactly is cryptocurrency? This guide breaks down the fundamentals of digital currencies, how they work, their benefits and risks, and the evolving regulatory landscape—especially in regions like China.
Understanding Cryptocurrency Basics
At its core, cryptocurrency is a type of digital or virtual currency that uses cryptography for security. Unlike traditional money issued by governments (like the U.S. dollar or euro), cryptocurrencies operate on decentralized networks based on blockchain technology—a distributed ledger enforced by a network of computers (nodes).
The first and most well-known cryptocurrency is Bitcoin, introduced in 2009 by an anonymous entity known as Satoshi Nakamoto. Since then, thousands of alternative cryptocurrencies—such as Ethereum, Dogecoin, and USDT (Tether)—have emerged, each with unique features and use cases.

Key Features of Cryptocurrencies
- Decentralization: Most cryptocurrencies aren’t controlled by any central authority, making them resistant to government interference or manipulation.
- Transparency: All transactions are recorded on a public ledger, visible to anyone on the network.
- Immutability: Once a transaction is confirmed, it cannot be altered or deleted.
- Security: Advanced cryptographic techniques protect funds and ensure transaction integrity.
How Does Cryptocurrency Work?
Cryptocurrencies rely on blockchain technology to function. Each time a user sends or receives digital coins, the transaction is grouped with others into a "block." This block is then verified by network participants (miners or validators) and added to the existing chain of blocks—hence the term blockchain.
Two common consensus mechanisms used to validate transactions are:
- Proof of Work (PoW): Miners solve complex mathematical puzzles to add new blocks (used by Bitcoin).
- Proof of Stake (PoS): Validators are chosen based on the number of coins they "stake" as collateral (used by Ethereum 2.0).
These systems ensure trust without relying on banks or financial institutions.
Popular Types of Digital Currencies
While all cryptocurrencies are digital, they serve different purposes:
- Bitcoin (BTC): Often seen as "digital gold," primarily used as a store of value.
- Ethereum (ETH): Supports smart contracts and decentralized applications (dApps).
- Stablecoins (e.g., USDT): Pegged to real-world assets like the U.S. dollar to reduce volatility.
- Meme Coins (e.g., Dogecoin): Originally created as jokes but gained significant followings.
Cryptocurrency in China: Legal Status and Risks
In China, the regulatory environment around cryptocurrency is strict. While owning digital assets isn’t explicitly illegal, trading and mining cryptocurrencies are banned. The People’s Bank of China has repeatedly warned citizens about the risks associated with crypto investments.
Moreover, foreign exchanges are prohibited from offering services to Chinese residents. This includes platforms facilitating Bitcoin, Ethereum, or USDT transactions.
Despite these restrictions, interest remains high. Some investors attempt to access offshore platforms, but this carries legal and financial risks. Legal experts emphasize that while holding crypto may not be criminal, facilitating large-scale trading or operating exchanges within China can lead to serious consequences.
“The Chinese government prioritizes financial stability and capital control,” says a financial analyst familiar with regulatory trends. “Cryptocurrencies challenge both, which explains the tight oversight.”
Common Misconceptions and Scams
Many beginners confuse digital currency with cryptocurrency. It's important to note that China is developing its own central bank digital currency (CBDC)—the e-CNY or digital yuan—which is fully backed by the government and operates under strict regulation. This is not the same as decentralized cryptocurrencies like Bitcoin.
Unfortunately, scams involving fake investment schemes, Ponzi structures, and fraudulent exchanges are widespread. Stories abound of individuals losing tens of thousands due to promises of high returns from so-called “virtual currency” projects.
One viral video recounts a trader who lost over 100,000 RMB playing volatile altcoins—calling it “worse than gambling.” These cautionary tales highlight the importance of education before investing.

Frequently Asked Questions (FAQ)
Q: Is buying cryptocurrency legal in China?
A: Owning cryptocurrency isn’t explicitly illegal, but trading, mining, and using it for payments are prohibited. Financial institutions cannot provide crypto-related services.
Q: What’s the difference between blockchain and cryptocurrency?
A: Blockchain is the underlying technology—a secure, transparent ledger system. Cryptocurrency is one application of blockchain, though the tech also powers supply chains, identity verification, and more.
Q: Can I invest in crypto through Chinese securities firms like Tianfeng Securities?
A: No. While companies like Tianfeng Securities analyze blockchain trends or数字经济 (digital economy) policies, they do not offer direct crypto investment products due to regulatory bans.
Q: Are stablecoins like USDT safer than other cryptos?
A: Stablecoins aim to reduce price swings by pegging to assets like the U.S. dollar. However, they still carry counterparty risk—if the issuer lacks sufficient reserves, the peg can fail.
Q: Will cryptocurrency be regulated more in 2025?
A: Global regulators are moving toward clearer frameworks. In China, further restrictions are likely rather than liberalization, especially concerning cross-border transactions.
The Future of Digital Finance
While China maintains a firm stance against decentralized cryptocurrencies, it actively promotes blockchain innovation within regulated boundaries. Reports from financial institutions like Tianfeng Securities highlight growth potential in areas such as:
- Artificial intelligence integration
- Virtual reality/augmented reality (VR/AR)
- Digital economies and元宇宙 (metaverse)
These developments suggest that while speculative crypto trading faces hurdles, the broader digital transformation of finance continues to advance.
