It is possible , but I don't think it will be done . Twitter differs from facebook in their advertizing and security policies. For me it was clear , that crypto ban from facebook is just a time question , this is a very centralized social media network.
But Fb might also introduce their own crypto.
Interested to see how that goes.
If facebook try to make its own crypto so its not relevant with this decision.
Or they want only advertise their onw blockchain so thats why another advertise from crypto is not allowed anymore?
