Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoinâs creator, Satoshi Nakamoto, originally described the need for âan electronic payment system based on cryptographic proof instead of trust.â Each and every Bitcoin transaction thatâs ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. Thatâs by design: Core to their decentralized nature, Bitcoins arenât backed by the government or any issuing institution, and thereâs nothing to guarantee their value besides the proof baked in the heart of the system. âThe reason why itâs worth money is simply because we, as people, decided it has valueâsame as gold,â says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
Telegram Auto-Delete Messages in Any Chat
Some messages arenât supposed to last forever. There are some Telegram groups and conversations where itâs best if messages are automatically deleted in a day or a week. Hereâs how to auto-delete messages in any Telegram chat. You can enable the auto-delete feature on a per-chat basis. It works for both one-on-one conversations and group chats. Previously, you needed to use the Secret Chat feature to automatically delete messages after a set time. At the time of writing, you can choose to automatically delete messages after a day or a week. Telegram starts the timer once they are sent, not after they are read. This wonât affect the messages that were sent before enabling the feature.
