Why would anyone even contemplate doing that, in the first place? The reason we don't know who Satoshi is till date should hit anyone why they shouldn't compromise their privacy. That's one. The second thing why I wouldn't touch the F2F thing, even with a long pole, is the lack of convenience it provides. Leaving my home to meet up with anyone for business transactions is a stress to me. I can only indulge such when it's the last resort. I like online transactions. I can't even remember the last time I walked into a bank to do my transactions. ATM transactions are also beginning to bore me too. So, with one trying to get all of that out of the way, why would one then subscribe to a face to face crypto deal that preaches much privacy? It doesn't make sense at all.
