Telegram Channels requirements & features Your posting frequency depends on the topic of your channel. If you have a news channel, it’s OK to publish new content every day (or even every hour). For other industries, stick with 2-3 large posts a week. The optimal dimension of the avatar on Telegram is 512px by 512px, and it’s recommended to use PNG format to deliver an unpixelated avatar. With Bitcoin down 30% in the past week, some crypto traders have taken to Telegram to “voice” their feelings. Polls
