Exchanges already said that they will BTU as an alt coin and now
with current happenings like another recent attack occured in BU nodes
I guess there will a dump and most likely BTU will fail if a hardfork happens. Well let's just wait and see.
I'm searching the forum for weeks now, but I haven't found any particular thread about the timing of the fork.
I can have a look at nodes and can compare the charts of BU, Core, etc supporter nodes. but that say nothing about fork and timing.
As I understood, it's not neccessary to do any communication before the fork, because it's just a software update on nodes. So it's possible that you will have only information that the fork has happened (but in that case all the bitcoin news sites will list it immediately)
