I am still not sure if this is good news or bad news...
While Tron have it's merits, this kind of means that the Steem blockchain will cease to exist (unless there is a hardfork creating two STEEMs) and will be part of the Tron blockchain.
Also, Tron and Justin sun have some image problems...
I honestly don't know.
I guess we will have to wait and see, especially how the current witnesses will position themselves about this...
