I have a little warning for the people who use any coin that implementing Zerocoin 
Zerocoin's technology require generation of "initial parameter", you can think about it as a "master key". This master key need to be deleted right after it was used and nobody should know about it. Technically, whole security of the currency depend on this "master key". Anyone who gained access to it would have ability to control double spend (i.e. he can create infinite amount of coin, another kind of premine).
The creation and destruction of this initial parameter need to be performed in a trusted way to make sure that nobody can know it, include the developer.
So, if you guy believe that dev is honest, you can use the coin. If you don't trust him, stay away from that.
That's my warning, i'm not trying to spread FUD, but this is some technical information people should know about Zerocoin
