This is just a reminder that Telegram bots, group chats and standard chats DO NOT HAVE ANY END-TO-END ENCRYPTION which makes all the chat logs stored on their servers and available to the Telegram law enforcement compliance team for further extraction any time later, without a need of employing any additional decryption.
This is correct, telegram only provides option for secret chats on mobile devices, but it's questionable how good that encryption really is.
If using telegram than it's better to use custom telegram numbers for registration, they can be purchased with crypto payments now.
I think more people should move from telegram to open source SimpleX chat, they have groups now, and maybe there is a way to create similar bots there.
