Aug. 27 (NBD) -- Chinese technology giant Baidu has blocked a number of forums related to digital currency on its online community Baidu Tieba, following Tencent's block on blockchain media accounts.

Alibaba Group's online payment app Alipay has also closed around 3,000 accounts that were engaged in virtual currency trade. 

According to a statement of Ant Financial, the financial unit of the Group, online stores which are involved in virtual currency trading will be shut down and Alipay accounts suspected of such trade will be banned from money collection. 

In addition, Chinese authorities released Friday a warning for illegal fund-raising in the blockchain sector. Some individuals are found to raise money in ways such as issuing virtual currency or virtual assets.

Lei Kai, associate professor at Beijing University Shenzhen Graduate School, told NBD that there exists information asymmetry among digital currency trading. Investors are unaware of the risks behind the investment in digital currency. A great deal of currencies actually didn't apply blockchain technology, Lei revealed.

Lei introduced that blockchain technology now is not mature but it boasts a broad prospect. 

He also noted the regulation of the activities relevant to digital currency involves efforts from different parties including media, exchanges and project sponsors.
