You are wrong, Telegram is one of the most safest channels to discuss about cryptos because no one is tracing your messages.
They are 100% encrypted, a lot of goverments, specially the US tried to compromise Telegram in order to see people's messages, but telegram denied it.
And seriously, email? are you paying attention to what you are writing in there? The emails are the most compromised channel that we have right now.
That is why a lot of people are now using protonmail, because it is descentralized.
Telegram is not a safe channel to discuss Bitcoin and future projects. The safest way would be through email.
If you actually read my post you would see that email means decentralized email because that is the closest to anonymity as it gets when sending messages. I just didn't name a source. ProtonMail is fine.
If you are suggesting that Telegram is the safest chat then you might be right.
