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?
If it really exists and the price is lower than normal, P2P wallet transfer is supported, and can exchange it for cash in my country
Money is money and bitcoin is bitcoin.
I have never really heard or seen anyone avoid “dirty” bitcoin because illegal activities may be linked to them but this is actually just a misconception of most people. The price of bitcoin is the price of bitcoin everywhere no matter where it was used or who previously had it.
