Telegram all the way. They have proven not to be scared to fight against governments. Russia didn't kill Telegram but the US could potentially kill Facebook.
I like Facebook more. Because in my country, 100 people will have only a few telegram accounts, but 90% will have a facebook account.
Facebook will be a more popular electronic currency, and will be a more effective advertising tool for crypto than telegram. more people will know crypto and the 4.0 era will come faster.
