Just a technicality here, but it doesn't matter whether it got "cancelled." The forking client was in the wild; there are still btc1 nodes online as we speak. The reason that the fork didn't occur is that the btc1 client broke. All btc1 nodes apparently got stuck at height #494,782 - 2 blocks before the fork was supposed to happen. I'm not sure that a block would have been mined once the fork occurred anyway, given the high difficulty and lack of user/service support.

I actually got "YOB2X" tokens credited to my account at 1:1 to my BTC on Yobit. I'm assuming this is due to B2X. People are buying it at 0.03-0.04 BTC for some bizarre reason.
