1. The volatility problem will still be there yes, but still way more manageable than it was in 2013 lol. In the future we will create pricing algorithms on the site so that the global payout rate is always in line with dollar value. For now the rate is set manually by us.
2. I do believe Elon has a serious commitment to free speech. Otherwise, why would he overpay $44 billion for a money losing company? I am following the money on this one... The free speech updates will take time, and have to be implemented in a controlled fashion. Many free thinkers are already being let back on the platform with many more to come.

4. Thank you so much for your support and interest!
