Some messages arenтАЩt supposed to last forever. There are some Telegram groups and conversations where itтАЩs best if messages are automatically deleted in a day or a week. HereтАЩs 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 wonтАЩt affect the messages that were sent before enabling the feature.
How Does Bitcoin Work?
Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. тАЬOnce a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,тАЭ says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means itтАЩs not controlled by any one organization. тАЬItтАЩs like a Google Doc that anyone can work on,тАЭ says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. тАЬNobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.тАЭ
