Before you have anything to do with GRAM coins you should know what rules they have.
They can turn off your account whenever they want!
I guess same thing we can expect from Libra and others...
Use of the Services.
4.2. Termination. We reserve the right to close, terminate or disable any or all of the Services, your user account, or your access to the Services at any time and for any reason.

Maybe they will ask for personal data in the future.
But i really like Telegram, that is can upload high res image and can make private chat.
I am still looking forward, is TON comfortable or not in the future.
