Dude, wakeup, there is no TRB fork.
for want of a better term, there are two coins existing in the current core chain. legacy coins (trb/satoshi/whatever you want tot call them) and segwit coins. sooner or later there will be a split to separate legacy coins out.
It is absolutely nonsense! Why should anybody suggest such a two-in-one perception at all? Why not n-in-1?.
And why should such a split occur at all and how is it going to convince people, economic majority or even a noticeable economic minority about stealing funds from SW transactions by miners for the god sake?
I'm smelling kinda conspiracy or something here: spreading words to run another ridiculous fork.
Am I right?
If so, why don't guys like you consider a meaningful, real fork to support a more ambitious and equally useful agenda?
Just leave SegWit and its junior hackers alone.
Think bigger. Segregated Witness is a joke, a trick, kinda cobbling up heterogeneous things, I admit, but just leave these guys alone with their lifetime achievement, build yours.
