But Elon Musk is a venture capitalist, he is someone who made his fortune doing these types of deals. He even said himself a few months before that buying twitter was a very bad idea. If you want to use hindsight had he taken a few months to do due diligence like he should have then he would have gotten it at a cheaper price. At the time when he made the bid it was a sensible one considering the stock price, I can't fault him for not timing the market but signing blindly that was utterly idiotic.
