N.V. = naamloze vennootschap and this literally means "nameless partnership" or "anonymous venture" and comes from the fact that the partners (the shareholders) are not directly known.
If this is a fact, nice fact for this. Do you have source of it or link so that we can base from it? Surely they want to remain anonymously if that is true, venture that wants to hide its identity but I guess it is better if they are going to let their gamblers who they are, the people behind the operation of satoshidice. But whatever it is, as long as they are going to fix their issues that will be better.
What issues has satoshidice?
If you guess it is better to let their gamblers know who the owner is, why do you promote betcoin.ag who even do not state the operator and make false and misleading statements about the applicable jurisdiction?
