What do you mean stop trading? They’re actually rumoured to implement trading on their platform as Elon Musk’s goal is likely have X to be a “super app” of some sorts. Elon seems to be a sort of “freedom” type of guy — with him being more lax with Twitter’s policies; this is evident with having the likes of Andrew Tate and Donald Trump unbanned.
Twitter was not a crypto trading platform so I think what he mean to stop the post about those but I'm not sure if I'm going to be impressed if they will implement trading there. I think I will still prefer Twitter to remain as social media site only because this makes them unique. He don't need to copy Facebook or to try harder to overcome it because he is still more superior than mark with all his business combined. If he want to, maybe he can acquire another website which is a trading platform.
I know it's another expense but he can surely gain the money that he used after some time because his many followers are going to support him by using the trading platform.
