China has blocked access to the two most popular Crypto market data sites- CoinGecko and CoinMarketCap. Both the sites are currently blocked by China's internet firewall. As per the search on Greatfire.org, the two sites are 100% blocked in China. However, it's not clear exactly when these sites became inaccessible to users. It was China's internet censorship agency that actively cut off Chinese IP access for CoinGecko and CoinMarketCap.
