Telegram is riding high, adding tens of million of users this year. Now the bill is coming due.Telegram is one of the few significant social-media challengers to Facebook Inc., FB -1.90% on a trajectory toward one billion users active each month by the end of 2022, up from roughly 550 million today.
Telegram has made it easier for its users to communicate, as it has introduced a feature that allows more than 200,000 users in a group chat. However, if the users in a group chat move past 200,000, it changes into "Broadcast Group", but the feature comes with a restriction. Groups with close to 200k members can be converted to a Broadcast Group that allows unlimited members. Only admins can post in Broadcast Groups, but everyone can read along and participate in group Voice Chats," Telegram added.
