I don't think it matters to ordinary users. They will have 0-conf instant transactions with Bitcoin Cash. The block can take hours to be mined but the transaction will not be in risk
Financial credibility requires the transaction to be already searchably verifiable inside a credible block of the chain. This is serious problem for paying travel expenses.
No, its not. A broadcasted transaction can be seen in a block explorer as "unconfirmed". BCH does not have RBF, so DS attack is close to impossible after 2 seconds.
That does not stop purchases being cancalled by vendors due to "confirmation delays". This is real and it happens to me a lot and probably many others. These are facts not 'hopium'.
I dare not name them, they are very good mostly, I still use them a lot. they sell airline tickets, My bookings were cancelled and thereafter unavailable. I rescheduled the trip.
