Regulatory Status of Cryptocurrency Trading in Mainland China
Since 2017, mainland China has implemented increasingly stringent regulatory measures on cryptocurrency trading and mining activities. Initially, seven departments, including the People's Bank of China (PBOC), jointly issued an announcement in September 2017, prohibiting initial coin offerings (ICOs) and requiring domestic Bitcoin trading platforms to cease operations. Affected by this, major domestic trading platforms at the time, such as Bitcoin China (BTCChina), stopped all trading operations by the end of September 2017. This move led to a short-term correction in Bitcoin's price, falling from approximately $4800 to $3655, with its market capitalization shrinking by nearly $20 billion.

Regulatory efforts further escalated in 2021. In September of that year, ten departments, including the People's Bank of China (PBOC), jointly issued a notice explicitly defining virtual currency-related business activities as illegal financial activities. This ban not only comprehensively prohibited the trading and speculation of virtual currencies but also explicitly covered the provision of services by overseas virtual currency exchanges to residents within China via the internet. Subsequently, several mainstream cryptocurrency exchanges, including HTX, OKEx, and Gate.io, announced the delisting of mainland Chinese users and ceased providing services to mainland Chinese residents.
The main reasons for the Chinese government's strict ban include: maintaining financial stability, preventing capital outflow risks, combating illegal fundraising, fraud, money laundering, and other criminal activities related to cryptocurrencies, and controlling high-energy-consuming mining activities. Additionally, the ban is also seen as conducive to promoting the digital yuan (e-CNY).
Despite the strict regulatory policies, market analysts point out that demand for cryptocurrencies still exists in mainland China, with some users participating in trading through alternative channels such as overseas exchanges or P2P markets. However, rumors about mainland China potentially lifting the cryptocurrency ban in the near future currently lack reliable basis, and it is generally believed that a significant relaxation of regulations in the short term is highly unlikely.
CoinMarketCap: A Leading Global Cryptocurrency Data Platform

In stark contrast to mainland China's trading platforms, CoinMarketCap (CMC) plays a completely different role in the global cryptocurrency ecosystem. It is important to clarify that CoinMarketCap is not a trading platform, but a leading global cryptocurrency price tracking website and data provider.
CoinMarketCap was founded in May 2013 by Brandon Chez with the aim of providing users with comprehensive, reliable, and real-time cryptocurrency market data. It quickly became one of the most popular and trusted data sources in the cryptocurrency space, with its data frequently cited by mainstream financial media such as CNBC and Bloomberg, as well as government agencies.
In April 2020, CoinMarketCap was acquired by Binance (Binance Capital Mgmt), the world's largest cryptocurrency exchange, but it continues to operate independently, committed to providing objective and impartial market data. As of the time of writing, CoinMarketCap includes data for tens of thousands of crypto assets and lists nearly a thousand exchanges.

CoinMarketCap provides core data including:
- Real-time prices: Tracks the latest prices of thousands of cryptocurrencies.
- Market capitalization: Displays the total market capitalization of each cryptocurrency, reflecting its market size.
- 24-hour trading volume: Measures the trading activity of cryptocurrencies within a specific period.
- Circulating supply: Shows the number of tokens currently available for trading in the market.
- Exchange rankings: Ranks major global cryptocurrency exchanges by comprehensively considering factors such as traffic, liquidity, trading volume, and confidence.
In addition to basic data tracking functions, CoinMarketCap also offers a range of value-added services, such as a learning section (CoinMarketCap Alexandria), crypto news, event calendars, portfolio tracking, price alerts, and API interfaces, to help users better understand the market and make decisions.
Summary

Mainland China's cryptocurrency trading market has largely ceased domestic operations under strict regulation, and users must strictly abide by local laws and regulations. CoinMarketCap, on the other hand, serves as a crucial data infrastructure for the global cryptocurrency market, providing transparent and comprehensive market information to users worldwide. The two play distinctly different roles in the crypto ecosystem.
