I think I've come to the conclusion that it is an illegal currency that would greatly benefit blackmarketing, fraud, money laundering, and potentially other forms of manipulation. I am still very intrigued and fascinated with the idea, but I get the feeling that this is ultimately a very bad idea. It's utility would be most useful in the worst possible ways. I can't decide as to what degree and/or magnitude these might be possible, but I'm thinking it should be avoided at all costs.
