โBanโ on Telegram A vandalised bank during the 2019 protest. File photo: May James/HKFP. The optimal dimension of the avatar on Telegram is 512px by 512px, and itโs 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 โvoiceโ their feelings. Members can post their voice notes of themselves screaming. Interestingly, the group doesnโt allow to post anything else which might lead to an instant ban. As of now, there are more than 330 members in the group.
