With the state of the world's financial systems as is we are not very far from being right back to this....
Many years ago people used to pay for escort services with livestock. Yes, you could barter for the company of a high-class escort with a couple of sheep and some goats.
And for those who cringe when people say bitcoin is anonymous, here it is again...
We recommend Bitcoin, because when compared to other methods of payment, it is anonymous and easy to use.
and again....
Your payment is rapid, secure, and anonymous.
On a serious note though, I think their prices is way to high. But then again, never paid for an escort before so will not really know.
