Are we supposed to be using BitCoinXT yet? I forgot when we are supposed to change, I'm lazy and haven't moved over or read about it.. I just don't want my 1 PH/s farm to abruptly work on the wrong chain.
No. That is never going to happen. Just keep mining with what you're used to.
I wonder why you didn't close this thread yet? XT is done, thus there is no need to discuss it.
