How to Create a Private or Public Channel on Telegram? Earlier, crypto enthusiasts had created a self-described โmeme appโ dubbed โgmโ app wherein users would greet each other with โgmโ or โgood morningโ messages. However, in September 2021, the gm app was down after a hacker reportedly gained access to the user data. The optimal dimension of the avatar on Telegram is 512px by 512px, and itโs recommended to use PNG format to deliver an unpixelated avatar. In 2018, Telegramโs audience reached 200 million people, with 500,000 new users joining the messenger every day. It was launched for iOS on 14 August 2013 and Android on 20 October 2013. Telegram offers a powerful toolset that allows businesses to create and manage channels, groups, and bots to broadcast messages, engage in conversations, and offer reliable customer support via bots.
