The owner of Twitter, Elon Musk, has said that the management of the social network is “quite painful” and “turbulent” and that he will sell the company if he finds the right person, the BBC reports.

Musk, who still heads carmaker Tesla and rocket company SpaceX, bought Twitter for $44 billion in October, and his personal fortune is estimated at nearly $190 billion, making him the second-richest person, according to a list of Forbes billionaires in the world.

In an interview with the BBC, which has attracted more than three million followers, when asked if he regrets buying Twitter, he said “the pain level is extremely high, and it’s not any fun”.
