The gold standard of encryption, known as end-to-end encryption, where only the sender and person who receives the message are able to see it, is available on Telegram only when the Secret Chat function is enabled.

They commonly offer unrealistic returns of as high as 1,000% within 24 hours or even within a few hours.
