Back in November it wasnt a recent announcement BTX has been around since APRIL  of last yr and is the oldest of all the BTC forks. However it is not a hardfork, but rather a hybrid or soft fork. Currently in February even with the rise of the difficulty its still one of the most profitable coins to mine with an Nvidia card, Amd arent recommended but can be used. 2 good pools to look at are Bitcorepool.cc or Omegapool.cc both run by ppl very close to the BTX devs.
