Bitcoin in/fiat out, or bitcoin in/bitcoin out?
By the looks of it, you put Bitcoin in and get credits. You spend the credits on the models and they get paid in fiat.
They missed a great opportunity to disrupt the web camming. They could have had the bitcoins flow from my pocket to the models pocket without any middle man. Then charge the model to use their services based on her income.
But then the couldn't exploit each model equally. No clue about how much of a cut they take, but I'm guessing they make a killing off of the models.
