Data from website traffic metric provider Similarweb shows that Deribit and OKX continue to attract significant traffic sources from China despite a blanket ban on crypto transactions and foreign exchanges last year.China has banned the use of cryptocurrencies more than a dozen times in the last decade. However, the one imposed in September last year was considered the harshest one. Several crypto exchanges including Huobi and Binance had shut doors for the Chinese traders in fear of regulatory action. The strict regulatory reforms ensured that Chinese traders mainly shifted their focus to decentralized exchanges (DEXs) and protocols.Chinese crypto traders have always found a way to bypass strict crypto regulatory measures imposed by the government. While many believed the blanket ban on crypto use would be a death sentence for the largely underground crypto market in China, geographical traffic data shows otherwise.A Cointelegraph exclusive report highlighted the rise in the use of VPNs among Chinese traders after the blanket ban. Recent data from Similarweb verifies that Chinese traders are still flocking to centralized derivatives platforms such as OKX and Deribit.Related: Residents of 3 Chinese cities paying taxes and charges with digital yuanHuobi was the primary choice of Chinese crypto traders as they accounted for more than 30% of the trading volume on the exchange before the blanket ban. However, now Deribit leads the chart in terms of Chinese traffic with a 12% share, followed by OKX with 9.6%.Another prominent reason for the rise in traffic on derivative exchanges could be the lack of strict Know Your Customer (KYC) measures when compared to the likes of Huobi and Binance.The geographical data shows that Russia, South Korea, the United States and Turkey were the biggest traffic source on centralized exchanges like Binance and Coinbase. Bybit and FTX were the most visited crypto exchanges in the month of April.
