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.

And it is very strange that they applied the same rule to wallets and the TON blockchain network.
It somehow does not fit well with the concepts of decentralization, do not you think?
