Yes, that's just proving the point. Not the opposite.
Did your brain roll out of your ear during your sleep last night? They just proved you were talking crap and don't know what you are talking about. You are a liar. The blockchain confirmed your transaction in under 45 minutes and you claim you sent it over 45 minutes ago. Don't even try to argue it is on the blockchain.
Well, he was "expecting" it to confirm in 25 minutes based on some fee estimate/confirm time estimate web site. Since reality didn't meet that estimate he concluded it took to long so no one would use bitcoin.
I still say that is faster than a Visa transaction and millions of those happen every day. No one complains that they are too slow since people use Visa constantly.
