With Bitcoin down 30% in the past week, some crypto traders have taken to Telegram to “voice” their feelings. When choosing the right name for your Telegram channel, use the language of your target audience. The name must sum up the essence of your channel in 1-3 words. If you’re planning to expand your Telegram audience, it makes sense to incorporate keywords into your name. Choose quality over quantity. Remember that one high-quality post is better than five short publications of questionable value. Those being doxxed include outgoing Chief Executive Carrie Lam Cheng Yuet-ngor, Chung and police assistant commissioner Joe Chan Tung, who heads police's cyber security and technology crime bureau. For crypto enthusiasts, there was the “gm” app, a self-described “meme app” which only allowed users to greet each other with “gm,” or “good morning,” a common acronym thrown around on Crypto Twitter and Discord. But the gm app was shut down back in September after a hacker reportedly gained access to user data.
