Now that we've established that going from WhatsApp to Telegram is a move that makes no sense at all: it's not safe, as discussed at UnhandledExpression, its "challenge" to hack it is no more than a publicity stunt for the ignorant masses, as Moxie sarcastically states, not to mention that if your reasoning is "I don't want Facebook to have all my data", switching to Telegram just means you can now worry about whether your contact info and that of all your friends went to the Russian big competitor VK, as your address book's numbers are saved onto their server, maybe it's time to shed some light on an alternative that does check all the right boxes, is as easy to use as WhatsApp, open source, and has people working on it that in fact know about encryption.
When having a get-together with some friends, one of us was anxious to show us a specific movie. None of us, however, were in the mood for a movie, being sure that we'd fall asleep. Nevertheless, we gave in and watched the movie. It was utter brilliance that reached us. Don't get fooled by the typical prejudices about films marked as 'science fiction', it simply doesn't apply to this movie. Furthermore, don't try to read anything about the movie before you see it, just watch it, it'll take only 80 minutes of your precious time, and it'll be well worth it. Jerome Bixby's The Man from Earth was the best movie I saw in 2007, without a doubt.
