Nah, it is used by the likes of my 87yo mother who wouldn't recognise a crypto if it landed in a tree nearby and doesn't speak a word of Russian (she's Dutch). It is used by those who shun anything MetaFacebook and as such won't install Whatsapp. As such I have used it in the past but now mostly use my own XMPP server although I still have it installed on several devices to keep in touch with those who remain on the platform. I do know a few words of Russian but that is unrelated to my (mostly former) use of Telegram.
