Twitter will let its users access stocks, cryptocurrencies and other financial assets through a partnership with eToro, a social trading company. Starting Thursday, a new feature will be rolled out on the Twitter app. It will allow users to view market charts on an expanded range of financial instruments and buy and sell stocks and other assets from eToro, the company told CNBC exclusively. This is apparently part of Elon Musk’s plan to turn Twitter into a “super app” that offers payments and banking. The entity formerly known as Twitter Inc. now seems to be named X Corp., reviving the name of Musk’s early online bank that eventually became part of PayPal.
