I doubt Aliexpress will start accepting bitcoin payments.
Aliexpress.com is owned by the Alibaba Group, which also owns Alibaba.com. In January 2014 Alibaba banned accepting bitcoins on its online marketplace (Taobao), and banned the sale of bitcoin mining equipment there. Its actions were viewed as a response to the People's Bank of China (PBoC) crackdown on bitcoin.

Alibaba's actions are seen as a response to the People's Bank of China (PBoC) warning against the use of Bitcoin last month as it looks to IPO this year and attempts to rid its marketplace site of fake goods.
