Yes, as stated above, I hope everything will be of legal character and also how to find ways not to attract the darker elements in society like drugs, porn, guns etc. Will there be a way to attract anonymous buyers without attracting the worst elements of our society at large?  . Just a question that is on my mind, of course even with fiat there has always been criminal activity, but with anonymous transactions, that could perhaps increase or drive the criminals more underground? Just a thought. The technology though is very interesting.
