If Twitter prohibits cryptocurrency advertising, I don't think it will have a major impact on the continuity of cryptocurrency, but instead I see that it will be detrimental to Twitter. restrictions on the use of cryptocurrency advertisements will be made by Twitter to prevent misuse of cryptocurrency.
this previously happened with google and facebook yet the community don't bother if they ban it and recently FB and google remove the banning because they see the profitability of crypto now I think twitter will soon realize it too.
