I have predicted that since Justin Sun has been active on Twitter to voice trading with TRON on various exchanges.
Because TRON was able to continue to be blown up by Justin Sun, I think the CEO of Twitter, Jack Dorsey, gave a prize of something valuable, the Emotion for the TRON logo.
Or maybe Justin Sun gave a little TRON to JAck Dorsey so that the TRON emotion could appear on Twitter, we don't know it will be happen !
