In 2018, Russia banned Telegram although it reversed the prohibition two years later. Individual messages can be fully encrypted. But the user has to turn on that function. It's not automatic, as it is on Signal and WhatsApp. Also in the latest update is the ability for users to create a unique @username from the Settings page, providing others with an easy way to contact them via Search or their t.me/username link without sharing their phone number. Messages are not fully encrypted by default. That means the company could, in theory, access the content of the messages, or be forced to hand over the data at the request of a government. The regulator said it has been undertaking several campaigns to educate the investors to be vigilant while taking investment decisions based on stock tips.
