Elon Musk bought Twitter for $44 billion and plans to increase the value of the social network to $250 billion by turning the platform into a digital bank.

Last week, the company’s CEO told his employees about his plan to 10x Twitter’s current value (about $20 billion), and at the heart of his plans is financial activity of millions of users.

This is a “remake” of Musk’s first steps with startup X.com, now famous for Paypal. The rapid success of Musk’s internet trading company earned him his first big fortune, which he then invested in Tesla and then founded SpaceX, which now has contracts with NASA.
