At the beginning of 2018, WeChat reached an important milestone. Over a billion people use the app every month. Started as a messenger, the service, which belongs to Tencent, can now also be used for mobile payment or online shopping, among other things. The majority of WeChat users live in China. Attempts to gain a foothold in other countries have so far been limited to reaching Chinese tourists. Although the app can also be downloaded in Germany, its competitor, especially WhatsApp, does not seem to be able to take any significant market share.
