If you work with cryptocurrency via Twitter, you will not be anonymous. The main question is, why would you work with cryptocurrency via Twitter if you have DEX? It's just that you'll have extra eyes following you - and there may be some problems that are not yet being talked about.
That's not a new concern, working on a centralized application will never be anonymous, and I think the "oversight" will be mostly done by eToro since they must have had such terms of use in place before the partnership happened. But don't worry, real traders don't play with their time using integrated trading apps that are not their thing.
Well, we all saw Elon's movement coming with twitter and Doge, now what Elon wants to do is seek to get Etoro afloat, for me it is a new platform but it is not yet crowded, what saves this broker is that it can do operations with bitcoin and some crypto, and now this will make it one of the brokers with the most searches and new registrations that will join them, because Elon is a great influencer here,any change he makes for his followers will always be the best , then this Movement Elon knew how to do.
