This is something every person can decide depending on their needs. Many people use WeChat for business, but probably an equal amount doesn’t. There are nearly half a billion WeChat users in China alone. It’s the most popular social network in the country. If your business or studies are connected to the region, you'll like to find many benefits in using WeChat. The app will also be helpful if many people you know are already using it, so you want to make sure to keep up with their Moments and allow them to see yours. It's a versatile app that might prove to be fun or useful, or perhaps both.
