Cash is more often used in money laundering and do you think that cash isn't even used for illegal activities? It's even the most used currency for those methods and this taboo about bitcoin must be changed.

Bitcoin is very much welcome in commercial use and from the perspective of being used illegally, that's changing into the mainstream day by day. It doesn't mean you use bitcoin because you are into illegal activities. You use bitcoin because you know that it's a good investment and a good alternative payment method.
