Quote from: AbraCadaver on June 22, 2012, 03:40 pmDepends entirely on what one would like to achieve by purchasing "clean" coins. Even if you purchase your Bitcoins on Mt. Gox with 100% legitimate money, you could expect persecutory behaviour from some financial regulation authorities. It has not started in earnest as of yet, but there are some small signs of it beginning (cash deposits to some exchanges through certain banks have become more difficult as I understand) An excellent point AbraCadaver, many thanks - what difference does it make even if Bitcoins can be said to be "clean" - all this would mean is that there's no definitive proof they've been used for a specific crime, this wouldn't necessarily stop Financial Regulatory Authorities in your home country from trying to clamp down on them!V.
