Elon have been trying to make good revenue through the Twitter acquisition. His plans didn't work, as he keeps making changes to the terms on the usage. Over the days after the acquiring the market of Twitter keeps decreasing due to the firing of staffs followed by the profile verification as premium services. Hate speech and eye same have made advertisers move out of Twitter causing major revenue loss. Even if the verified users prefer the blue tick service then it might bring another $400 - $500 million in revenue every year. The first loan settlement will give the outlie of his further plans for selling of his alternate stocks or had some other plan.
