Yes, but not to the point of paranoia. While I understand people's sentiment about p-2-p encryption, some people really do overreact about the lack of it in Telegram atm.

If anybody really wants to hack you (you exatly) - p-2-p ecryption won't stop them, this is not some kind of absolute defence.

And if you are worried about FSB readin your messages - trust me, they don't, unless you are under suspection already. No organisation in Russian history ever worked this way, only selectively.

Facebook's acquired messenger product uses Signal Protocol for end-to-end encryption. From a security perspective, WhatsApp and Facebook Messenger are materially, categorically more secure than Telegram.

Hi, we've had this discussion before. You say the crypto is better, which is true, I say it's unverifiable and it has a company behind it with a bad track record for privacy, which is also true. Still we can't agree on which one to use.
