Chain split tokens on BFX.
I don't think I have any of those. They were gifted to you at the time of the not-fork?
There was supposed to be a hard fork for S2X at blockheight 494,784 which had no replay protection and was supposed to stir panic among the natives. But the fork broke because of shitty coding so this weekends Bcash epic pump and dump never got off the ground. So there hasnt been a fork and now almost certainly wont be because the main chain is too far ahead.
So you wont have any because they dont exist. The BFX 2X tokens are futures for delivery of a currently non-existent coin that you can buy and sell on BFX before the fork. Leaving some rather unhappy bag holders today.
Eventually people will learn not to trust Chinese miners but probably not yet.
