Everyone uses WhatsApp. But some use it better than the others. They know it in a better way, they know its hidden codes, and the settings that aren't obvious. They know about its less-known features. And not only they know about the ways that are not so common, they also use this knowledge to put to use WhatsApp in a way that is more efficient, safer and at times more fun.
That is unlike how most of the people use. Since its introduction in 2009, WhatsApp has grown into an app that allows users to do much more beyond, in various ways. It wasn't always like this. There was a time when WhatsApp used to be much more simpler. But since 2014 or so, almost every month WhatsApp has acquired new features and new settings. These have changed it from a mere chat app to a versatile app that can not only also make calls but nowadays even allows people to exchange money.
