Some of the exchanges outside of the USA with all it's KYC/AML regulations will be in a better position to answer this, but I doubt that they will... basically because it will put them in the spotlight and if
other people knows how, they will become the competition. I would like to see some sort of decentralized exchange, but I guess that will be even more difficult.. because you have to deal with the fiat
side of things. I have to agree with one of the previous posters... this is a good question, and I would like to see the answer to this too.
