This is crazy. How can an exchange exist without anybody knowing where it is? Wouldn't credit card payments or bank transfers create a money trail? Has nobody decided to do detective work to figure this out? I never knew this was possible to create a website and be able to anonymously collect money without a trail. I remember somebody recommending Hitbtc has a secure exchange. I don't remember ever hearing anything bad about it, but now it seems everywhere.
You would really be surprised by the number of exchanges that people don't know where their offices are located.
AFAIK, Hitbtc doesn't provide any fiat-related services. They do accept credit card payments but they're doing it through Changelly which is just another shady exchange. Either way, I doubt it would be easy to track them down, not for the average joe anyway.
