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. There have been several contributions to the group with members posting voice notes of screaming, yelling, groaning, and wailing in different rhythms and pitches. Calling out the “degenerate” community or the crypto obsessives that engage in high-risk trading, Co-founder of NFT renting protocol Rentable World emiliano.eth shared this group on his Twitter. He wrote: “hey degen, are you stressed? Just let it out all out. Voice only tg channel for screaming”. A new window will come up. Enter your channel name and bio. (See the character limits above.) Click “Create.” Matt Hussey, editorial director of NEAR Protocol (and former editor-in-chief of Decrypt) responded to the news of the Telegram group with “#meIRL.” With Bitcoin down 30% in the past week, some crypto traders have taken to Telegram to “voice” their feelings.
