The models don't give anybody a show until they've got paid just like they would any other way. In fact with CC they do because they wont receive the money instantly unless anyway. You send BTC to the models then when they receive either the first confirmation or them all - doesn't really matter - you get your show. Simple. You're making this more complicated than it already is with your limited understanding of Bitcoin and how it works.
Why on my link they talking about 12-24 hours for confirmation??
Sure, i have no clue, how it work for instant services. I only listen, that is recommended to wait some 12 hours for cheap items to deliver and more, if items are expensive.
