I am imagining this is what jbreher meant by "bcash has 0 confirmation transactions".
Hmm. I don't remember saying anything of the sort. I do remember confirming your suspicion that zero conf were once again usable under BCH. But that's a horse of a different color.
I mean, any crypto "has 0 confirmation transactions". Many cryptos, however, make them less than usable. Bitcoin Segwit, for example, goes above and beyond to eliminate the possibility with RBF.
