Telegram has made it easier for its users to communicate, as it has introduced a feature that allows more than 200,000 users in a group chat. However, if the users in a group chat move past 200,000, it changes into "Broadcast Group", but the feature comes with a restriction. Groups with close to 200k members can be converted to a Broadcast Group that allows unlimited members. Only admins can post in Broadcast Groups, but everyone can read along and participate in group Voice Chats," Telegram added.
Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoinβs creator, Satoshi Nakamoto, originally described the need for βan electronic payment system based on cryptographic proof instead of trust.β Each and every Bitcoin transaction thatβs ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. Thatβs by design: Core to their decentralized nature, Bitcoins arenβt backed by the government or any issuing institution, and thereβs nothing to guarantee their value besides the proof baked in the heart of the system. βThe reason why itβs worth money is simply because we, as people, decided it has valueβsame as gold,β says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
