First and for all Ned didnt made much in the past 2 years. Steem didnt had any marketing to onboard new users. Plus they was keep selling they tokens.

Now lets talk about Justin. He is a investor. As a investor i dont think it makes sense to kill your investment straight after u bought it. If he put steemit on tron as far as i know there should be a fee for transactions. So i am asking who will post or make something if he have to pay for that. Even just a micro amount.
But Justin have money and team to make steemit better. He is good at marketing. What else we need?
Justin want profit so it means we steem holders should have also. So I think we dont need to overreact or worry.

Ok maybe i am mistake but these are my thoughts at the moment.
