Twitter's mMAUs (monthly Monetizable Active Users) stands at 450 million. If they pay $8 per month, that gives Elon $3.6B per month. It will take 13 months to make $44B - the purchase price QED. Elon Musk is a genius.
Of course he is a businessman, he still need to get his money back, but then if these changes are being implemented I wonder how far can we use Twitter, we all know that we used Twitter in our crypto life everyday, all of the crypto projects uses Twitter to create announcements and reach people that's why even though Twitter will soon have a subscription price I believe many will still purchase it.
