Seriously, I would have just walked away at that point. In all my years of F2F exchanges I have only had 1 person ever ask for ID, and due to the amount I could not blame him totally.
Didn't give it, pointed out we were in a casino with about a million cameras and that was the point. He was just worried that since it was over $10K that it was some sort of entrapment thing. I just didn't want to fly with that much cash, and hey.... it was in Vegas. We made the deal. So it was all good in the end.
If you are passing that much cash in a coffee shop I can see it being a different story.
How do you guys perform Face to Face exchange? How does the process go?
I mean, you have to check whether cash is fake or not, then that person has to be sure that you are really sending coins and aren't going to cancel your transaction and both of you should wait for at least for one confirmation. I mean, if you don't do a deal in a public place in front of cameras or near police, there is a chance that one of you will quickly run away. If you do it in front of cameras, I think it will look suspicious for everyone. I have only exchanged iPhone in real life and I know I can block iCloud and feel safe but once bitcoins are gone, they are gone forever.
By the way, it looks logical to ask for an ID during exchange because what if the coins that you sent me are from dark web? And I am the only one who will experience problems when I decide to deposit coins from this wallet to casino/exchange?
