That's an interesting question. How did you come up with that idea and why exactly would you like to buy it, if it existed?

There are no such dirty BTC, BTC is a fungible coin where every coins is same without any exception. Don't listen to those bullshit i.e. centralized exchanges who're make Bitcoin become non fungible coin since they didn't treat every coins in a same way.

So, you must avoid to use those bullshit, choose the exchange from kycnot.me.
